IMPORTANT Engine Change
From mid 2004 the Lister Petter TS2 and TS3 engines were replaced by the Lister Petter TR2 and TR3 engines. The TR range of engines is completely interchangeable with the TS range and consumable items such as filter elements are identical. There are some internal component differences and when ordering spares it is important to state whether it is a TS or TR engine.
Instructions and notes found throughout this manual which refer to TS engines are also applicable to the TR engine

Introduction
The following procedures should enable experienced service personnel to strip, repair and rebuild Winget 300R and 400R Reversing Drum Concrete Mixers in a safe and competent manner. The procedures are not intended to be used by personnel who are unfamiliar with the product nor mechanically inexperienced.
It is assumed that personnel are aware of Health and Safety Regulations which should be applied to all working practices, but the following should act as a reminder.
Ensure all work tools are in good condition.
Always wear Safety Spectacles when using Soft or Hard Faced Hammers, Chisels or when using Air Tools. Wear Safety Spectacles when cleaning hardened concrete or mortar off components.
Do not misuse Air Lines and be aware of the damage Compressed Air can cause if misused.
Always make sure lifting equipment is in good condition and the Safe Working load exceeds the weight of the components to be lifted.
Oils, Fuels, Silicone Sealers and Open Gear Lubricants can cause skin diseases if allowed to contaminate the skin. Always apply barrier creams, wear suitable protective clothing, or when contamination is unavoidable clean the area with soap and water as soon as possible. Do not use thinners or other solvents to clean skin.
Health and Safety is a matter of common sense. If common sense is applied correctly Health and Safety can be improved and the risk of accidents reduced.
Refer to the Parts Listings in Section 10 or the Parts & Operators Manual for a guide to the correct sequence for assembling components and sub assemblies.
It is assumed for the purposes of this manual that the machine is standing on firm level ground and is horizontal in both planes.

Lifting Points
Lifting Points capable of supporting the weight of the Mixer are incorporated in both of the Water Tank Supports just below the height of the Drum Top Guard.
The Lifting Points are highlighted with an ISO ‘Hook’ symbol adjacent to each Point.
On Military/Nato mixers the Lifting Points are also painted white.
The Hopper also incorporates Lifting Points to assist in removing the Hopper. The L/H Point is used to secure the Hopper Safety Chain which is attached to the raised Hopper during maintenance work. The Hopper Lifting Points are not highlighted to avoid confusion with the main lifting points. On no account must the Hopper Lifting Points be used to support the weight of the mixer.
Drawbars – Standard & Military/Nato
The Drawbars are retained to the Front axle by two ‘L’ shaped retaining pins which are in turn secured by two lynch pins c/w chains which are inserted through the retaining pins once the drawbar is in position. To remove the drawbar first remove the lynch pins, withdraw the retaining pins and lift the drawbar clear, refit the retaining pins and prevent their loss by refitting the lynch pins. Reverse the procedure to refit the drawbar.
Military/Nato Towing Eye (Used with Military/Nato Drawbars)
Remove the split pin, castle nut and flat washer retaining the eye in the drawbar. Remove the eye. To refit reverse the above procedure, do not fully tighten the nut, allow the eye to rotate in the drawbar. New eyes will require drilling for the split pin when fitted in place.
Jack Legs
To remove a Jack Leg either jack up and support the machine or using suitable lifting equipment lift the machine. Pull out the retaining pin remove the leg. Refit in the reverse order.

Gearbox from the Mainframe, using suitable slings and lifting equipment lift the Gearbox clear of the Mainframe .
Reassemble in reverse order ensuring the centreline of the Engine and Gearbox are in line by shimming as necessary to avoid straining the Couplings and Flanges.
Engine Removal
On Electrical Start Diesel and machines fitted with a Dragline and Alternator, isolate the Battery and disconnect the wiring. Split the Driveshaft between the Engine and Gearbox at either the Twiflex or toothed drive coupling. Unbolt the Engine from the Mainframe, disconnect the Air Cleaner pipework. Using suitable lifting equipment lift the Engine clear taking care not to lose the two engine packers. (Note later ‘CE’ machines are fitted with guarding over the propshaft.) Reassemble in the reverse order ensuring the centreline of the Engine and Gearbox are in line by shimming as necessary to avoid straining the Couplings and Flanges.
Air Filter
The Air Filter is located on the Engine/Fuel Tank Shroud on the R/H side of the mixer. During operation dust collected the body is ejected through the rubber valve in the side
of the filters cylindrical body. The Element, which should be removed daily for cleaning and replaced at least once every 300 hours or three months is retained in the main body by a large wing nut, which when released allows removal of the element for cleaning.
Hydraulic Tank
The Hydraulic Tank contains a Suction Filter suspended below the Tank Lid. To access, clean any debris from the top of the tank, disconnect the Hydraulic Pipework from the Tank Lid, plug all hoses and blank off all fittings, remove the screws and carefully lift off the Lid to avoid damaging the lid seal. Unscrew and clean the filter.

Controls. Stop the engine and allow the oil in the Tank to settle for approximately two minutes before rechecking the level.
Note:
The Hydraulic Systems holds approximately 22 Litres (5 gallons) of oil.
Located on the top of the tank is the Bleed Valve which allows oil discharged from the single Acting Hopper Ram (as the Ram lowers the Hopper) to bleed back into the tank.
If replacing the Bleed Valve body, ensure that the Ball in the Body forms a good seat by driving the Ball down on the seat using a soft faced punch.
The tank is retained in the Mainframe by three M10 setscrews, however it is not possible to remove the Tank unless the Gearbox is first removed.
Hydraulic Pump
The Hydraulic Pump is located on top of the Gearbox secured by four setscrews and is driven through the Gearbox Bevel Gears, via a Pump Mounted Bevel Pinion. If replacing a Bevel Pinion on the pump be aware that many pumps have more than one keyway cut into the tapered shaft, selecting the wrong keyway will result in premature shearing of the key.
Hydraulic pumps should be shimmed to give 5-8 Thou (0.02-0.20mm) gear backlash.
Place the Pump Assembly onto the Gearbox without any shims and measure the gap between the pump body and gearbox casting. Add 5-8 thou (0.02-0.20mm) to the measurement obtained and select the correct number of shims.
Hydraulic Control Valve
The Hydraulic Control Valve is mounted on the L/H side of the machine below the step being secured to its bracket by at least two bolts, nits and washers.
Lifting the control lever raises the Hopper whilst lowering the lever lowers the Hopper.
The Control Valve powers the Single Acting Hydraulic Ram and also provides oil for the Dragline Winch Motor via a High Pressure Carryover located in one of the control valves ports. The adjustable system relief valve is located in the Control Valve and apart from a spool seal kit no and handle kit no other user serviceable parts are available.

Hopper Ram & Restrictor
Lift the Hopper and support with the Safety Chain provided.
Disconnect the ¼ bore hose leading from the Header Tank to the Ram cylinder and plug the hose to prevent oil loss. Remove the bolt retaining the Upper Pivot Pin through the Hopper Cradle and knock out the pin. Do not lose the Washers placed each side of the Ram Eye. Allow the ram to drop forward, the upper eye bush is now visible and can be replaced if necessary. When replacing the upper bush with the ram in situ it is important that the ram is prevented from moving from side to side. When fitting a new bush ensure the lubrication hole in the bush is aligned with the grease nipple.
To remove the Ram Assembly, disconnect and plug the Hydraulic Hose and the Restrictor on the Ram port. Remove the bolt retaining the lower pivot pin through the Mainframe. Support the Ram with suitable lifting equipment and knock out the lower pin.
Lift the Ram Assembly clear drain out any oil and support in a suitable soft jawed vice. Clean the area around the end cap and attaching a suitable tool unscrew the end cap, carefully remove the rod and piston assembly and secure in a soft jawed vice.
Examine the cylinder bore carefully for signs of scoring or corrosion and the piston rod for signs of pitting or peeling, it is pointless attempting to reseal a ram which has a damaged bore or rod.
Remove the split pin securing the Piston Nut and remove the Nut, Piston Assembly and End Cap. Remove and discard the old seals, new seals should be soaked in clean hydraulic oil before fitment. Ensure all components are clean. Fit the new seals, rebuild the Ram in reverse order fitting a new split pin through the piston retaining nut.
The Restrictor screwed into the Ram Inlet/Outlet port restricts the flow of oil out of the Ram as the Ram is closed ensuring a more controlled descent.
The Restrictor contains a spring and Poppet valve and does not usually cause problems in service.
Note:
The Hydraulic Ram is single Acting and in operation when the Ram is closed the majority of the Hydraulic Oil is discharged from the full bore side of the Ram. To avoid condensation forming in the annulus (upper) side of the cylinder as the Ram is closed, oil is drawn into the annulus side from the Header Tank to fill the void with oil, this oil is expelled back into the Header Tank as the Piston raises extending the Ram and lifting the Hopper.
The Header Tank contains a sight glass and it is important that the oil level within the Tank is checked on a daily basis. The oil level is correct if it is just visible in the sight glass when the ram is fully closed.

Hose Failure Valve
Machines bearing the “CE” mark indicating compliance with the EC Machinery Safety Directive have a Hose Failure Valve fitted to the Ram Inlet/Outlet port in addition to the restrictor.
In service it is not unusual for violent operation of the Control Valve (In order to shake material free from the Hopper when the Ram is at the full extent of its stroke) to blow off the relief valve activating the Hose Failure Valve. Which then prevents closing of the Ram and lowering of the Hopper.
Should this occur, slowly lift the Hopper slightly by extending the Ram without blowing off the relief valve, then slowly close the Ram lowering the Hopper. Once the Hopper has lowered by approximately 300mm normal operation can be resumed.
If a new hose failure valve is to be fitted the valve should first be unscrewed from the body, and the gap between the valve baffles adjusted to 2mm by means of the small capscrew and nut. Following adjustment, the valve should be screwed fully home into the body and operation of the machine checked when it is fitted.
Hopper, Cradle, Link Arms and Pivot Shaft
Link Arms
The Hopper Cradle pivots on Needle Bearings contained within the “L” shaped Link Arms.
To remove the Arms lower the Hopper Cradle and block up the Hopper to prevent the assembly dropping when a Link Arm is removed.
Remove the Bearing Caps, each secured with three setscrews which pass through the Caps and Arms into the Bearing Housings. Remove the Nut and Flat Washer retaining the Link Arm to the Shaft, pull off the Arm, retrieve the Housings and “O” Rings from the Pivot Shafts.
Remove the Inner Bearing of the Shafts, using a suitable bearing tube and soft faced hammer remove the Outer Bearings from the Link Arm.
Reassemble in the reverse order greasing the Needle Bearings on Assembly.
Hopper Cradle and Hopper
Removal
Raise the Hopper slightly to allow access to the Hopper retaining bolts and nuts, attach suitable lifting equipment to the Hopper, remove the bolts and carefully lift the Hopper clear.

Attach the lifting equipment to the Hopper Cradle, raise the Cradle to allow removal of the upper Ram pivot pin, lower the Cradle. Remove both Link Arms and the Link Shaft which passes through the Cradle, lift the Hopper Cradle clear.
Reassemble in reverse order.
Pivot Shaft
The Pivot Shaft is retained in the “A” frame by two grubscrews one each end of the Shaft.
To remove the Shaft carry out the procedures describing removal of the Hopper, Link Arms and Cradle. Remove the Inner Bearings from the ends of the Shaft. Remove the grubscrews and using a soft faced hammer knock out the Shaft.
Reassemble in reverse order coating the Shaft with copperslip and ensuring the Shaft is central in the “A” frame before tightening the Grubscrews.
Batchweigher
The Batch Weigher Gauge is located on the L/H Water Tank Support and is mounted on rubbers to dampen vibrations. The Gauge is connected to the Loadcell which is located in the Mainframe below the Hopper Cradle via a hydraulic pipe.
The Loadcell and Gauge must be considered a sealed unit and on no account must the hydraulic pipe be removed.
Damage to the Gauge or Loadcell is most commonly caused by dropping a loaded Hopper onto the Loadcell, allowing an empty Hopper to free fall directly onto the Loadcell or filling the Hopper directly from a Site Dumper, Skid Steer Loader, Tipping Lorry or other similar equipment.
These cause high shock loadings which can loosen the Needle Pointer in the Gauge, damage the Loadcell seals, or cause the top half of the Loadcell to turn over at an angle.
Although the both Workshop Manual and the Operators Manual contains instructions for overhauling the unit, it is recommended that the Loadcell and Gauge Assembly are returned to Winget Limited whenever possible for repairs. Field service and repairs can often cause complications and accurate calibration of the Assembly cannot be guaranteed. Winget Limited can accept no responsibility should attempts be made to overhaul or repair the units.
Assuming the Loadcell and Gauge are in good condition the most common causes of inaccurate weighing are:-
1) Mixer not level
Ref: SHSC1216
Page 21
WORKSHOP MANUAL
300R 400R
WINGET REVERSING DRUM CONCRETE MIXERS
ISSUE 8 2012
2) Hopper resting on ground or build up of waste material below Hopper. Ensure at
least 50mm (2”) clearance between the ground and Hopper.
3) Build up of material around the Hopper Cradle Link Shaft.
4) Worn Hopper Cradle Pivot Bearings.
5) Loadcell Striker guide fouling Mainframe or failing to rotate freely.
6) Worn Loadcell Striker Pin.
7) Failure to Re-Zero Batchweigher Gauge by means of the Zeroing knob on the
side of the Batchweigher Gauge.
Batchweigher Adjustment
Should the Batchweigher require adjustment the following procedure should be carried out.
With the Loadcell Striker resting on the Loadcell, check the top of the Link Arms are horizontal to within 2-3mm, and the Link Shaft is clear of the holes on the Cradle, if not, adjust the packing below the loadcell.
Check the Loadcell Striker is resting centrally on the Loadcell button, if not, slacken the setscrew below the Loadcell and adjust its position, or slacken the grubscrews securing the Hopper Cradle Pivot Shaft to the “A” frame and move the assembly over. Tighten the screws following adjustment.
Check the Loadcell Striker is at approximately 25 degrees to the Hopper Cradle, if not, adjust by altering the Loadcell Striker packing between the Striker and Hopper Cradle.
Place known weights in the Hopper to check the Gauge reading progressively throughout its range.
To increase the Gauge reading at low loads, increase the amount of packing below the Loadcell.
To increase the Gauge reading at high loads, increase the amount of packing behind the Striker.
Loadcell Striker Guide
The Loadcell Striker Guide is mounted in the Mainframe just behind the Loadcell, and rotates on Needle Roller Bearings.
To remove the Guide, raise and support the Hopper. From inside the Mainframe remove the grubscrew retaining the Guide Pivot Pin. Knock out the Pin and Lift the guide clear.
Prise out the Seals and using a suitable bearing tube and soft faced hammer remove the Needle Roller Bearings.

Reassemble in reverse order coating the Pivot Pin with copperslip, and ensuring the Guide rotates freely and does not foul either side of the Mainframe.
Feed Apron
Two or Three Compartment Feed Aprons are designed to assist the flow of materials into the Hopper in conjunction with a Dragline.
The Feed Aprons consist of L/H and R/H side panels, Base Panel, Centre Dividers (one or two depending on the option chosen) Support Bar, Rubber Flap, (to prevent materials falling between the Hopper and Apron) and Rubber Retainer.
To assemble the Feed apron, place the Base smooth side up in front of the Hopper, lay the Rubber Flap on the Base and secure with the Retainer and countersunk screws.
Using a suitable support raise the Base so that the Rubber is approximately 520 millimetres (1’8”) off the ground and the Base slopes back at an angle, bolt both Side panels in place. Remove the support so the weight of the Base is taken by the side Panels. Fit the Support Bar between the Side Panels and bolt the Centre Dividers in place.
Check that the Rubber Flap projects slightly out over the Hopper Mouth and that both are in line, stake the Feed Apron securely in place using the four picketing lugs, two on each Side Panel.
The Feed Apron can be extended backwards to separate aggregate by fitting boards into the ends of the Side Panels and Centre Dividers.
Dragline Electrical System
Two different electrical systems or method of power generation are utilised depending on the engine or electric motor fitted.
Hand Start Lister-Petter TS & Electric Motor
When a Hand Start Engine or Electric Motor are fitted, the Gearbox drives via a “V” belt a 12 volt automotive type Alternator. This is in turn connected via 2 core cable to a Panel Mounted Isolator Switch and Warning Light. A Battery (acting as a storage device for the Alternators output) mounted on the R/H side of the mainframe, through a Two Pin Plug and Socket to the Shovel Mounted Operating Button/Switch and on to the Dragline Solenoid Valve.
The most common causes of electrical failure are:-
1) Break in the two core cable between the Shovel mounted Button/Switch and the
Socket and Plug mounted below the Winch Motor. (If the Cable is shortened do not reduce the length to less than 19.8 metres, 65 feet).
Ref: SHSC1216

2) Dirty or loose electrical connections at the Plug and Socket, at the Solenoid
Valve, at the Alternator or Battery.
3) Bad Earth Connections.
4) Worn or badly adjusted “V” Belt.
5) Worn or dirty Alternator Brushes.
6) Failure to turn on the Isolator Switch before starting the Engine or Motor.
7) Flat Battery.
Voltage/Setting Instructions
It is not possible to adjust the Voltage Setting but the voltage can best be measured at the Terminal Block on the Solenoid Valve.
Remove the Terminal Block, Connect a D.C. Voltmeter to the Terminal Block, operate the Isolator Switch and start the Engine or Motor. Depress the Shovel mounted Button/witch and note the voltage reading, it should not exceed 14.5 volts. If the Voltmeter indicates a negative reading or reads in the reverse direction interchange the Voltmeter leads.
Electric Start Lister-Petter TS
When an Electric Start Engine is fitted the Charging System built into the Engine provides the electrical power to operate the Dragline Solenoid Valve.
Power is taken from Terminal 2 on the Ignition Switch, through 2 core cable via a Plug and Socket through the Shovel Mounted Operating Button/Switch, back through the Plug and Socket down to the Dragline Solenoid Valve (See Wiring Diagram).
The most common causes of electrical failure are:-
1) Break in the two core cable between the Shovel Mounted Button/Switch and the
Socket and Plug mounted below the Winch Motor (If the cable is shortened do not reduce the length to less than 19.8 metres, 65 feet).
2) Ignition Switch in the “Off” position.
3) Dirty or loose electrical connections at the Plug and Socket, the Solenoid Valve,
Ignition Switch or Battery.
4) Flat Battery.
5) Charging System Failure (See Engine Workshop Manual).
6) Bad Earth Connections.

If the Voltmeter indicates a negative reading or reads in the reverse direction interchange the Voltmeter leads.
Dragline Winch Motor
The Dragline Winch Motor is mounted on a bracket which is supported across the Water Tank supports, the hydraulic motor itself contains no user serviceable parts and should be replaced in the event of failure. The motor and winch drum are protected by a removable cover which is retained by two setscrews and nuts.
Four replaceable Nylon or Steel Rollers are mounted directly in front of the Winch Motor and allow the Wire Rope to operate without damage. The Rollers are retained by long through bolts and self locking nuts which are removed to allow replacement of the rollers. NOTE:- The position of the rollers can be alternated to even up the wear on them and prolong their service life.
Operation of the Winch Motor is controlled by the Shovel Mounted Button/Switch via the Solenoid and Dragline Control Valves.
When correctly piped up the Winch Motor rotates in a Clockwise Direction to pull the Dragline Shovel in and freewheels in an Anti-clockwise Direction when the Dragline Shovel is being pulled out by the Operator.
If the hoses to the Winch Motor are disconnected they should be marked to aid identification and both the hose ends and fittings in the Motor plugged to prevent the ingress of dirt or foreign matter. The Dragline Winch Motor circuit is protected by a secondary ‘relief valve’ contained in the Dragline Control Block.
Refer to the Dragline Hydraulic System Description on Page 26 for further information.
Dragline Control Block
The Dragline Control Block is mounted onto and above the Solenoid Valve, and in conjunction with the Solenoid controls the hydraulic oil flow to the Winch Motor.
The Control Block contains no internal user serviceable components apart from a simple Relief Valve, the setting of which is altered by adding or removing Shim Washers to increase or decrease the Spring Setting which in turn increases or decreases the hydraulic pressure to the Dragline Motor.
Refer to the Hydraulic System Description for additional information.

ISSUE 8 2012
Dragline Solenoid Valve
The Dragline Solenoid Valve contains no user serviceable parts, and if checks of the electrical system indicate it is faulty it must be replaced.
Oil leaks between the Valve and Control Block indicate the failure of the small ‘O’ rings which can be replaced following removal of the Solenoid Valve which is retained by four socket headed capscrews.
Refer to the Hydraulic System Description for additional information.
Hydraulic System Description
The Basic Hydraulic System is simple in design consisting of a gearbox mounted Hydraulic Pump, Main Hydraulic Tank onto which is mounted the Bleed Valve, the tank also contains the Suction Strainer. A Header Tank connected to the annulus side (full bore or upper) of the Hopper Ram with a drain hose to the main hydraulic tank. A Single Spool Control Valve and Single Acting Hydraulic Cylinder onto which the Flow Restrictor and Hose Failure Valve are also fitted. The Hose Failure Valves are only fitted to those machines intended for use within the European Community.
The Pump is driven by the gearbox drawing oil from the Tank through the Suction Strainer. The Pump delivers the oil to the Control Valve, if the Valve Control Lever is in the neutral position the oil is directed back to the tank through the tank return line. (When a Dragline is fitted the threaded adaptor on the tank is fitted with an additional Tee piece to allow for extra return lines)
When the Control Lever is raised to lift the Hopper, the Valve Spool directs the oil through the tank mounted Bleed Valve down to the Ram where it passes through the Hose Failure Valve (where fitted) and Flow Restrictor before operating the Cylinder.
The tank mounted Bleed Valve is designed to ensure that when the Hopper is fully lowered, no residual pressure remains in the circuit between the Cylinder and Control Valve which could affect the Batchweigher readings. The Bleed Valve contains a Ball
and Spring and is ported to allow oil to flow back into the tank. Oil flowing under pressure from the Control Valve to the Cylinder enters the top of the Bleed Valve and acts on the Ball which is depressed against spring pressure closing off the Tank Port thus directing oil to the base of the Cylinder.
If the Control Lever is returned to neutral during the lift or lowering cycle, the pressure created in the circuit between the Cylinder and Control Valve by the weight of the Hopper acting on the Cylinder, is sufficient to hold the Ball on the seat within the Bleed valve, preventing the Hopper from dropping. (Should the Hopper continue to drop the Ball/Seat within the Bleed Valve possibly requires attention).
Ref: SHSC1216
Page 26
WORKSHOP MANUAL
300R 400R
WINGET REVERSING DRUM CONCRETE MIXERS
ISSUE 8 2012
If the Control Lever is operated to lower the Hopper, the weight of the Hopper displaces oil out of the Cylinder, pressure in the circuit is not sufficient to retain the Ball on its seat and oil returns to the tank via both the Bleed Valve and Control Valve.
When the Hopper is fully lowered the residual pressure in the pipework between the Control Valve and Cylinder is dispersed through the Bleed Valve, allowing the Hopper’s weight to act fully onto the Batchweigher Loadcell.
The Header Tank connected to the annulus side of the Single Acting Ram is designed to ensure the cylinder is always full of oil preventing changes in climatic conditions causing the formation of damaging condensation. The oil level in the Tank can be checked on a daily basis when the Hopper is lowered via the sight glass built into the face of the Tank. The level is correct when it is just visible in the sight glass, should the tank be overfilled the excess oil will be returned to the Main Tank via the overflow/return pipe.
In service it is expected that over time oil under pressure will migrate from the full bore side of the cylinder into the annulus side, passing the piston seals as they wear. This migration will increase the level of oil in the Header Tank whilst at the same time lowering the oil level slightly in the Main Tank, once the oil in the Header Tank reaches a certain level the excess will return via the return/overflow pipe to the Main Tank.
Excessive topping up of the Header Tank may cause an increase in the oil level within the Main Tank, levels should be monitored on a regular basis and the levels reduced if necessary.
Dragline Hydraulic System
The Dragline Hydraulic System consists of a 12 Volt Solenoid Controlled Oil Distribution Block (otherwise known as the Dragline Control Block) containing an adjustable Relief Valve. A Hydraulic Motor is fitted to operate the Dragline Winch. The system is continuously supplied with oil whilst the engine is running via a High Pressure Carryover at the Main Control Valve.
When the 12 volt Solenoid is not energised, oil flow from the Main Control Valve is directed by the Distribution Block direct back to the hydraulic tank through the centre return line which terminates on the tank lid/cover. The supply and return hoses supplying oil to the Winch Motor from the Distribution Block are at the same time ported within the Block to form a closed loop enabling the Winch Motor to revolve freely with minimum resistance when the Dragline Shovel is manually pulled backwards by the operator.
When the 12 volt Solenoid is energised by operating the Shovel Button/Switch, the tank return is closed, the loop is opened and oil is directed to the Winch Motor which revolves reeling in the Dragline Shovel. Oil exiting the Winch Motor is returned to the Distribution Block where it is directed down the second return line through the tank mounted tee piece, back into the tank.
Ref: SHSC1216
Page 27
WORKSHOP MANUAL

WINGET REVERSING DRUM CONCRETE MIXERS
ISSUE 8 2012
Should for any reason the Motor jam or seize in operation the Relief Valve in the Distribution Block should “Blow off” dumping the oil down the return line via the tee piece back into the tank.
Relief Valve Adjustment
Main Relief Valve
With the Engine or Electric Motor at rest and the Hopper fully lowered ensure no residual pressure remains in the hydraulic system by operating the hydraulic control lever a number of times. Check and top up the hydraulic oil level.
Disconnect the supply hose to the top of the Bleed Valve, attach a suitable tee piece to the Bleed Valve and reconnect the hose. Connect a Hydraulic Pressure Gauge to the tee piece. The gauge should preferably be a minimum of 75mm in diameter with a minimum scale reading of 3500 psi and should be attached to a length of two wire hydraulic hose C/W crimped adaptors which is long enough to reach to the operator’s station by the Control Valve.
Start the Engine or Motor and allow to run until the oil is warm. Operate the Control Valve raising the Hopper to its maximum height until the relief valve ‘blows off’ note the maximum pressure recorded on the gauge, it should read 2000 psi (138 BAR) If the reading is higher or lower the Relief Valve requires adjusting. Lower the Hopper, stop the Engine or Motor and disperse any residual pressure as described above. If the Hose Failure Valve has ‘locked out’ the Ram follow the procedures described on page 17 to release. Slacken the Relief Valve locking nut (some valves may be protected by a removable cap) and identify whether the Valve is adjusted by means of a screwdriver or hexagon key.
Start the Engine or Motor and raise the Hopper again to momentarily ‘blow off’ off the relief valve, noting the reading, release the Control Valve Lever to neutral and adjust the relief valve either clockwise or anti clockwise dependant on whether the pressure requires increasing or decreasing. Do not turn the valve more than ¼ turn each time an adjustment is made, after each adjustment ‘blow off’ the relief valve noting the pressure obtained until the correct pressure is recorded.
Lower the Hopper, stop the Engine or Motor, disperse any residual pressure and remove the gauge, hose and tee piece. Reconnect the supply hose directly to the Bleed Valve, clean up any oil spills and check the oil level within the tank. Top up if necessary.
Dragline Relief Valve
Check the Main System oil pressure as described above. Disperse any residual oil pressure. Identify and disconnect at the Dragline Control Block the feed hose from the Dragline Control Block upto the Winch Motor, plug the open end of the hose. Attach to the Dragline Control Block in place of the hose removed the hydraulic test gauge c/w

with length of hose but without the tee piece, this will form a ‘dead head’ within the circuit as the oil can go no further than the gauge.
Operate the Dragline Isolator Switch (handstart and electric machines only). Start the Engine or Motor, there should be no need to allow the oil to warm up as it should still be warm from the previous tests, momentarily depress the Switch /Button on the Dragline Shovel to ‘blow off’ the relief valve and note the reading on the gauge. Do not unduly hold down the Switch/Button, only depress long enough to obtain a reading then release otherwise a steep increase in oil temperatures will be experienced and damage may be caused to the hydraulic system.
The gauge should read a maximum of 1500psi (103BAR), to adjust stop the Engine or Motor and disperse any residual pressure. Identify the large hexagon on the side of the Dragline Control Block which is the head of the relief valve and carefully unscrew, withdraw the hexagon which incorporates the spring guide, the bonded seal, spring and poppet valve. Small flat washers are placed on to the spring guide to increase the tension on the spring thereby increasing the pressure, removing a washer will reduce the pressure. During initial manufacture one washer is placed on to the spring guide and this is usually sufficient but over time in service the spring may weaken and require additional washers adding. Add or subtract a washer as may be necessary, refit the relief valve assembly and repeat the procedures described above to recheck the pressure.
Failure to attain the required pressure may indicate a worn or sticking poppet valve or worn seat.
Water Tank Description
The Tank is designed to automatically shut off the flow of incoming water once the desired measured quantity (between 10-75 litres/2-16 Gallons) is achieved.
Mounted on the front of the Tank Body is a Graduated Scale and Carrier, passing through the Carrier is a Pointer and Pivot Pin. Once the Pointer is set to the required amount on the Scale the Pointer and Scale Carrier are locked together with a wing nut and coach bolt.
Both the Scale Carrier and Pointer Pivot Pin pass into the interior of the Tank where the Scale Carrier terminates in a Cam, the Pointer Pivot Pin carries the Float Arm and Plastic Float Assembly and terminates at the Operating Lever.
Moving the Pointer along the Graduated Scale effectively raises and lowers the height of the Float Assembly in the Tank.
Mounted on the outer L/H side of the Tank adjacent to the Scale Carrier is the Water Inlet containing the Water Strainer. Attached to the Water Inlet on the inner face of the Tank is the Water Inlet Valve assembly.

WORKSHOP MANUAL
300R 400R
WINGET REVERSING DRUM CONCRETE MIXERS
ISSUE 8 2012
The Water Inlet Valve consists of a Body and Cover sandwiching a Brass and Rubber Diaphragm. The Cover is machined to carry the sprung Pilot Valve.
Water enters the Valve Body through the Strainer filling the chamber acting on the rear rubber face of the Diaphragm, causing the Diaphragm to stretch and lift off its seat and allowing water to enter the Tank.
There is a “pin hole” orifice in the centre of the Diaphragm which allows water to pass through into a second smaller chamber in the Valve Cover where the Pilot Valve is located.
The Pilot Valve is held off its seat, against spring pressure, by the Trip Lever allowing the water to bypass the Pilot Valve and bleed into the Tank via a drilling in the Cover, thereby preventing water pressure building up in the second chamber. The Trip Lever is operated by the Cam located on the end of the Scale Carrier.
Water entering the Tank through the Inlet Valve very quickly reaches the level of the Float set by the Pointer which is locked to the Scale Carrier and Cam. The rising water level lifts the float/Pointer/Scale Carrier and Cam assembly causing the Trip Lever to “trip”, allowing the Pilot Valve to close preventing incoming water bleeding out of the second chamber.
Incoming water is still passing through the orifice but because it can no longer escape past the Pilot Valve, water pressure in the smaller second chamber increases equalling the pressure in the first chamber allowing the stretched Diaphragm to return to its original position, closing off the incoming water.
A seal is maintained by the Diaphragm against the first chamber due to the differential areas in the two chambers, i.e. the second chamber now has a greater effective surface area than the first chamber.
Pulling down on the Operating Lever opens the Discharge Valve in the base of the Tank discharging water into the Drum.
Pushing up on the Operating Lever closes the discharge Valve, resets the Trip Lever and opens the Pilot Valve allowing water to enter the tank once again.
The most common symptoms of Water Tank failures and their causes are:-
1) Reduced water flow – blocked Water Strainer or insufficient head of water or lack
of water pressure.
2) Water leaking from the discharge Pipe – Worn or perished Discharge Valve
Rubber Seat or corroded Valve.
3) Float failing to lift – punctured Float.

4) Water Flow failing to stop when Pilot Valve closed – ruptured Diaphragm, worn or
perished Pilot Valve “O” ring, worn Pilot Valve, weak Pilot Valve spring or blocked orifice.
5) To high a water pressure causing the Diaphragm to rupture or stretch
Strainer Replacement
Turn off the water supply. Remove the hexagonal plug from the strainer body, lift out the strainer, clean or renew. Refit in reverse order sealing the threads of the plug with P.T.F.E. tape and threadseal. Turn on the water supply and check for leaks.
Diaphragm Replacement
Turn off the water supply. Remove the split pins retaining the trip Lever pivot pin through the Inlet Valve Cover, remove the binx nuts securing the pin to the Operating Lever and Scale Carrier Support. Slide out the pivot pin retrieving the Trip Lever.
Remove the eight setscrews (seven short, one long) holding the Valve Cover to the body retrieving the fibre or nylon washers. Lift off the cover and remove the Diaphragm. Clean out the Body and Cover.
Fit the new diaphragm, inspecting for damage, note the Brass Face should face the Pilot Valve. Reassemble the Valve, replacing any damaged Fibre or Nylon sealing washers. Do not overtighten the setscrews retaining the cover or the Diaphragm will not operate correctly and the fibre washers may split.
On completion adjust the long setscrew opposite the Trip Lever so that when the Pilot Valve is closed the gap between the head of the setscrew and triplever is 1mm.
Pilot Valve and “O” Ring
Follow the previous instructions under Diaphragm Replacement and remove the Inlet Valve Cover.
The Pilot Valve is retained in the Cover by a split pin, flat washer and Spring. Remove the Pilot Valve and “O” Ring. Reassemble in reverse order following the instructions under Diaphragm Replacement.
Float
Turn off the water supply. Loosen the locknut slightly and unscrew the Float. Fit the new Float in the same position on the Float Arm to avoid upsetting the Tank Calibration.

Discharge Valve and Rubber Seat
Turn off the water supply, drain and remove the Tank. Remove the Water Outlet Pipes from the base of the Tank retrieve the Rubber Seat.
Slacken the locknut slightly and unscrew the Discharge Valve Rod from the Connector attached to the Operating Lever, remove the Discharge Valve and Rod through the opening in the Tank base. Knock out the Roll Pin securing the Discharge Valve to the Rod.
Reassemble in the reverse order screwing the Discharge Valve Rod back to its original position in the Connector to avoid upsetting the Tank Calibration. Renew the plastic sealing washers on the Water Outlet pipe if damaged.
Water Tank Adjustment and Calibration
Following major overhauls of the Water Tank it will be necessary to re-calibrate the Graduated Scale, Scale Carrier, Pointer and Float Assembly to ensure the Tank delivers the amount of water pre-set on the Graduated Scale.
A large set of platform scales with a minimum reading of around 200lbs and a water collection tank of around 25 gallons capacity will be required to calibrate the Tank and the following procedures should be carried out.
1) Connect a suitable water supply to the Water Inlet, it will be more convenient for
the purposes of the test if a shut off tap is located adjacent to the Tank.
2) Check that the ends of the Graduated Scale align with the outer edge of the
Scale Carrier, loosen the wing nut and make sure the Pointer and Float Arm move freely.
3) Checking the Discharge Valve is closed, turn on the water supply allowing water
to enter the Tank through the Inlet Valve until the water is level with the top of the baffle within the Tank. The height of the baffle equates to a water level of five gallons. Turn off the water supply. Allow the Pointer/Float to stabilise and check the reading on the Graduated Scale. Depending on the distance the Pointer is from the 5 gallon mark on the Scale either, move the Scale along the Scale Carrier to align with the Pointer, shorten the Float Arm by screwing further through the Pointer Pivot Pin or slightly bend the Float Arm so the Pointer and Graduated Scale are correctly aligned on the 5 gallon mark. Open the Discharge Valve and drain the Tank. Close the Discharge Valve resetting the Tank.
4) Place the collection tank on the platform scales and position below the Water
Discharge pipe. Zero the platform scales.
Ref: SHSC1216

ISSUE 8 2012
5) Set the Pointer to the 5 gallon mark on the Graduated Scale and tighten the wing
nut. Turn on the water supply and proceed to fill the Tank through the Inlet Valve. When the Float trips the Lever shutting off the flow of water into the Tank, turn of the water supply, open the Discharge Valve discharging the water into the collection tank.
Check the weight registered by the platform scales, as a gallon of water weighs 10lbs the platform scales should read 50lbs.
If the reading is lower than 50lbs bend the Float Arm slightly, raising the Float, thereby allowing more water to enter the Tank before the Float trips the Inlet Valve.
If higher than 50lbs bend the Float Arm to lower the float and re-test from “5”.
6) When the 5 gallon/50lbs test is successfully completed, set the Pointer to 15
gallons and re-test, a reading of 150lbs should be achieved on the platform scales.
7) Drain the Tank, refit to the mixer.
