1 . 1 . GENERAL :
ROTATION & PORTS INDICATION
All Parker vane motors are individually tested to provide the best qua­lity & reliability. Modifications, conversions & repairs can only be done by authorized dealers or OEM to avoid invalidation of the guarantee.
The motors are to be used within the design limits indicated in our sales bulletins. Please contact Parker when tresspassing the catalogue limits.
Do not modify or work on the motor when it is under pressure.
Qualified personnel is required to assemble and set-up hydraulic de­vices.
Always conform yourself to the valid regulations (safety, electrical, en­vironment...).
The following instructions are important to obtain a good service life time from the unit.
Internal parts of the motor are lubricated by the operating fluid itself ; therefore, preventive maintenance is limited to keep the fluid clean in the system, and within acceptable viscosity range. The system filters should be replaced frequently. When possible, dirt should not be allowed to accumulate on the motor or around the shaft seal. Check frequently that all fittings and bolts are tight at correct torque.
The rotation way and ports orientation are viewed from the shaft end.
R = CW stands for clockwise = right-hand rotation. A inlet, B outlet L = CCW stands for counter-clockwise = left-hand rotation. A inlet, B outlet N = Stands for bi-rotational, A inlet, B outlet = R (CW) B inlet, A outlet = L (CCW)
DESCRIPTION
APPLICATIONS
The M5AS* series is a new design of vane motor. It has been designed especially for severe duty applications which require high pressure, up to 280 bar (4060 PSI).The 12 vanes patented cartridge allows very low noise level whatever the speed is, a low torque ripple, and high efficiencies.
The M5AS* single vane motor consists of five basic components :
- the housing (housing and shaft seal)
- the pressure plate (plate, ball, adaptor and screw)
- the cartridge (cam ring, rotor, vanes and springs)
- the end cap (cap and needle bearing)
- the shaft assembly (shaft, ball bearing, retaining ring and key) The design of the Parker motors allows to change the cartridge, to renew the motor or to change the displacement to suit altered require­ments for speed or torque.
The M5AS* motor has a stiff taper or cylindrical shaft and a high load capacity double ball bearing, and allows direct mounting on shaft (fan, belt drive, chain drive). For uni-directional applications, the M5AS* is fitted with an internal val­ve which allows smooth dynamic braking, with a very simple hydraulic circuit, without risk of motor cavitation.

OPERATION
The cartridge is a replaceable assembly,
including cam ring, rotor, vanes and springs.
Operation of these rugged hydraulic motors is simple. The motor shaft is driven by the rotor. Vanes, closely fitted into the rotor slots, move radially to seal against the cam ring. The ring has two major and two minor radial sections joined by transitional sections called ramps. These contours and the pressures exposed to them are balanced diametrically. Light springs urge the vanes radially against the cam contour, assuring a seal at zero speed, so that the motor can develop starting torque. The springs are assisted by the centrifugal force at higher speeds. Radial grooves and holes through the vanes equalize hydraulic forces on the vanes at all times. Fluid enters and leaves the motor cartridge through openings in the side plates at the ramps. Each motor port connects the two diametri­cally opposed ramps. The rotor is axially separated from the sideplate surfaces by the film of oil. The front sideplate is clamped against the cam ring by the pressure, maintening optimum clearance as dimensions change with tempera­ture and pressure. A three way shuttle valve in the sideplate causes clamping pressure in port A or B, whichever is the highest. Materials are chosen for long life efficiency. Vanes, rotor and cam ring are made out of hardened high alloy steels. Cast semi-steel sideplates are chemically etched to have a fine crystalline surface for good lubri­cation at start-up.
The floating side plate contains a shuttle
valve wich passes the highest pressure
signal to the clamping area.
Cam ring is interchangeable with others
of different displacements.
Major arc where fluid
works to push the
vane.
START UP & CHECK UP
Side grooves and radial holes cause undervane
and overvane pressure to be equal.
Check that the assembly of the power unit is correct :
The distance between the suction pipe & the return lines in the tank should be at its maximum.
A bevel on both suction & return lines is recommended to increase the surface and so lower the velocity. We suggest a 45° minimum angle.
M5 velocities : inlet x < 6 m/s (x < 20 ft per sec.) : return under pressure x < 6 m/s (x < 20 ft per sec.) : return low pressure x < 3 m/s (x < 10 ft per sec.) : Always insure that all return and suction lines are un­ der the oil level to avoid forming aeration or vortex ef­ fect. This should be done under the most critical situa­ tion (all cylinders extended for example). Straight and short pipes are the best.
Q (l/min) Q (GPM)
V = = m/s V = = ft/s
6 x p x r
The size of the air filter should be 3 times greater than the max. instant return flow (ex: When all the cylinders are in movement ).
A coaxial drive is recommended. For any other type of drives, please contact Parker.
Make sure that all protective plugs & covers have been removed.

PRIMING
COLD STARTING
The tank has been filled up with a clean fluid in proper conditions.
We recommend to flush the system with an external pump prior to the start-up.
It is important to bleed the air off the circuit and the motor itself. Manually, fill the motor housing with fluid, and connect the motor to the circuit. Start rotation in a jogging manner until a prime is picked up, and in­crease the speed from 500 to 1000 rpm. Check that there is no leakage or air suction neither at the ports (inlet, outlet, drain), nor at the shaft end. If the motor does not prime properly in the first minute, or pressure can not be obtained, it should be shut down and condition corrected.
The motor should be started at low pressure and low speed until the fluid warms up, before running it at high pressure or speed.
The first valve on the circuit should be open to tank.
We recommend the use of air bleed off valves.
Warning : this has to be done in low pressure mode as it could create a dangerous fluid leak. Make sure that the pressure cannot rise (open center valve to tank, pressure relief valve unloaded ...).
When oil free of air appears, tighten the connectors to the correct tor­que.
1 . 2 . SHAFT & COUPLING DATA : COUPLINGS AND FEMALE SPLINES
KEYED SHAFTS
TAPERED KEY SHAFTS
The motor should prime within a few seconds. If not, please consult the troubleshooting guide (pages 32 & 33).
If the motor is noisy, please troubleshoot the system.
• The mating female spline should be free to oat and nd its own cen­ter. If both members are rigidly supported, they must be aligned within 0,15 TIR (0.006” TIR) or less to reduce fretting. The angular alignment of two splines axes must be less than ± 0,05 per 25,4 radius (± 0.002” per 1” radius).
• The coupling spline must be lubricated with a lithium molydisulde
grease, disulfide of molybdenum or a similar lubricant.
• The coupling must be hardened to a hardness between 29 and 45
HRC.
• The female spline must be made to conform to the Class 1 t as des­cribed in SAE-J498b (1971). This is described as a Flat Root Side Fit.
Parker supplies the M5AS* series keyed shaft motors with high strength heat-treated keys. Therefore, when installing or replacing these motors, the heat-treated keys must be used in order to ensure maximum life in the application. If the key is replaced, it must be a heat-treated key between 27 and 34 R.C. hardness. The corners of the keys must be chamfered by 0,76 mm to 1,02 mm (0.03 to 0.04) at 45° to clear the radii in the key way.
The alignment of keyed shafts must be within tolerances given for spli­ned shafts here above.
The torque for a steel coupling and a nut, of at least grade 8.8 quality is 80 Nm (59 ft.lbs)
SHAFT LOADS
It is compulsory to install a castle nut + cotter pin when right hand ro­tation and bi-rotational.
The max. permissible load values are given in the sales catalogue.

1 . 3 . SPECIFIC POINTS : VERTICAL MOUNT
MOTORS IN SERIES OR HIGH BACK PRESSURE
PIPE
THREADED PORTS
EXTERNAL DRAIN
When assembled vertically, always be careful to prevent any air from being trapped in the motor housing.
Please contact Parker.
All fluid lines, either pipe, tubing or hose, must be of adequate size and strength to assure free flow to and from the motor. An undersized inlet line will restrict the fluid flow to the motor and prevent proper operation by creating turbulences and aeration. If rigid pipe or tubing is used, the workmanship must be accurate in order to eliminate strain on the motor housing or the fluid connectors. Sharp bends in lines should be eliminated whenever possible. All the system piping must be cleaned with solvent or an equivalent cleaning agent before being connected to the motor. Do not use galvanized pipe. Galvanized coating may flake off after continued use.
To be mounted in accordance with SAE J1926/2, ISO 6149/2 and ISO
1179.
These externally drained motors must have a drain line connected to the center housing drain connection of sufficient size to prevent back pressure in excess of 3.5 bar (50 PSI), returning directly to the reser­voir below the surface of the oil, and as far away as possible from the suction pipe of the pump. It is preferable to install the center housing with the drain hole upward to facilitate the purge of the motor. If the motor is mounted shaft up, the drain line must have a bend above the motor to purge it and to be sure that the shaft seal is lubricated (see drawing).
MINIMUM REPLENISHMENT PRESSURE DURING DECELERATION
The hydraulic circuit should be designed in a way that when switching off the hydraulic motor, it remains supplied with fluid, without risk of cavitation (anti-cavitation valve may be needed). Uni rotational M5AS* Motors are fitted with an internal anti-cavitation valve.

Vane troubleshooting guide
7 . TROUBLESHOOTING GUIDE :
1 . No rotation
2 . Stalls easily
a) Is the flow coming at the motor?
b) Is the torque requi­red higher than the system settings?
c) Is the pump OK?
d) How is the motor piped?
a) Is the load close to the limits of the sys­tem?
b) Is the flow going to the motor sufficient?
a-1) Check the circuit and the hydraulic schematic. Is the piping O.K.? a-2) Check the setting of the main pressure relief valve. a-3) Check if the pump is delivering flow. a-4) Check if the directional valve is allowing the flow to go to the motor. Check if the directional valve is energized. If it is, check if the spool is in its correct position and not sticking in a position that would deviate the flow somewhere else. a-5) Check if a check valve would not have been wrongly mounted.
b-1) Check if the pressure settings are correct. b-2) Check if the load is not superior to the torque capabilities of the motor.
c-1) Check if the pump is working correctly.
d-1) Check the nature of the connectors. If, for example, the “self sealing quick couplings” type connectors are well locked into each other.
a-1) Check the relief valve setting value and compare it to the theoretical pressure required to deliver the convenient torque.
b-1) Check the minimum flow required by the motor. b-2) Check the flow of the pump or the valve feeding the motor.
3 . Not enough speed
4 . Erratic speed
c) Is the anti-cavitation valve closed?
a) Is the speed lower than desired?
a) Is the motor loosing speed erratically?
c-1) Check that the valve is OK (properly installed, ball seat pollution).
a-1) Check the theoretical displacement of the motor versus the theoretical flow of the pump. a-2) Check that the flow of the pump is really arriving at the motor. a-3) Check that the working pressure & speed are in accordance with the catalogue values of the motor. a-4) Check the fluid temperature. Check then that the low viscosity of the fluid is not having a big effect on the internal leakage of the motor. a-5) Check the air bleed-off.
a-1) Check if the limit of the allowable torque is not reached once a while. a-2) Check if the driven device does not transmit some inconstant load. a-3) Check if the flow coming from the pump is constant.

Vane troubleshooting guide
7 . TROUBLESHOOTING GUIDE :
5 . Unusual noise level
6 . Unusual heat
a) Is the motor run­ning?
b) When is the motor braking?
a) Is the fluid arriving to the motor already hot?
b) Is the fluid heating up when going throu­gh the motor?
a-1) Check if there is no air intake that could aerate the fluid. a-2) Check if the motor is not cavitating. It could be that the inertia of the load is such that it drives the motor faster than the flow coming from the pump. a-3) Check if the fluid is suitable for the use. a-4) Check if the air bleed off has been done properly.
b-1) Check the back pressure to see if the replenishment pressure is not too low, leading to cavitation of the motor.
a-1) Check if a cooler is required or, if there is one, if it is well dimensio­ned. a-2) If there is a cooler, check if it is working (example for water cooler : is the water flow open or sufficient). a-3) Check if the hydraulic circuit is not bringing back the flow directly to the inlet port. Doing so, it would create a small closed circuit not able to cool down the fluid. a-4) Check the quality of the fluid. a-5) Check the velocity of the fluid (6 m/s max.). a-6) Check the filtration unit, its capacity. a-7) Check if the heat does not come from an open bypass valve.
b-1) Check the speed of rotation versus the catalogue values. b-2) Check the pressure rating. b-3) Check the fluid type. b-4) Check the viscosity.
7 . Shaft end leakage
a) Is it leaking when pressurized?
b) Is it leaking when standing still?
a-1) Check that the shaft bearing is not damaged (dark grease leaking out of the ball bearing). a-2) Check that the drain line is not too much pressurized, wich could have destroyed the shaft seal inside the motor (fluid leaking outside the shaft bearing race). a-3) Check that the environment, the fluid temperature and viscosity are appropriate (melted grease due to too high temperature or oil leakage due to a burned shaft seal). a-4) Check if there is no high overshoot at start-up that would create a high instant internal leakage. a-5) Check, when using a “quick coupling connector” for the drain line, that it is correctly locked. a-6) Check the alignment of the shafts.
b-1) Check that the shaft bearing is not damaged (dark grease leaking out of the ball bearing). b-2) Check that the drain line is not too much pressurized, which could have destroyed the shaft seal inside the motor (fluid leaking outside the shaft bearing journal). b-3) Check that the environment, the fluid temperature and viscosity are appropriate (melted grease due to too high temperature or oil leakage due to a burned shaft seal).
