NOTE: Flow (GPM/LPM) based on 100% volumetric efficiency. Horsepower and kilowatts required are based on 85% overall efficiency.
Horsepower requirements are at Myers pump input shaft. The efficiency of the hydraulic pump, hydraulic motor, etc. must be considered to determine horsepower required to drive complete system.

GENERAL INSTRUCTIONS
CAUTION: Positive Displacement Pumps must
have a proper size and operable type of pressure regulating valve or pressure relief valve piped into the discharge line. This is mandatory to prevent damage to pump and piping or possible injury to personnel. DO NOT install any valves or shut-off devices in the bypass line from pressure regulator to tank or supply.

BELT DRIVE SEWER CLEANERS
With belt drives, pulley on both engine and pump should be located as closely as possible to bearing to reduce bearing and shaft bending loads. Make sure that all bolts, nuts, set screws, and keys are properly tight­ened.

STARTING PUMP
A. Before Starting:
1. Read all instructions carefully.
2. Fill pump crankcase with recommended oil to level mark on oil saber. Oil recommendations are covered in lubrication section of pump instruc­tions.
3. Replace all drain plugs in pump and piping.
4. Inspect tank to be sure that no foreign material is in tank or suction line.
5. Fill tank at least half full or connect suction to water supply. Open valve (if present) in suction line. Avoid prolonged dry operation which may
cause excessive wear on cylinders and piston packing. Be sure that an operating pressure gauge is located in discharge line.
6. Make sure all valves, including spray gun or nozzles, are open in discharge line. Spray gun may be anchored to discharge back into tank.
7. Completely back off pressure adjusting screw on pressure regulating valve.
B. Starting the Unit:
1. After starting, close discharge valve or spray gun slowly while watching pressure gauge to make sure relief valve or unloader is operating properly.
2. Adjust relief valve or unloader to desired pres­sure. See regulator instructions.
3. Cycle nozzles or gun on and off to be sure that pressure adjustment and regulator operation is satisfactory.
NOTE: Nozzle capacity should not exceed 90% of pump capacity for satisfactory regulator operation. AVOID FREEZING by draining all water from pump and system in cold weather.

SUGGESTED MAINTENANCE SCHEDULE
OPERATION INTERVAL
Check oil level Daily Drain and change oil 300 hr. (1) Replace piston packing 500 hr. (2) Inspect valves and springs 500 hr. (3) Inpsect connecting link bearing inserts 1000 hr. (4) Inspect crankshaft tapered roller bearings 2000 hr.
(1) Drain at operating temperature to prevent contamina-
tion from setting.
(2) Inspect frequently for leakage; replace before 500
hours if any cylinder exceeds 10 drops per minute leakage. Packing may not look badly worn but will
often be shiny and hard and won’t seal well. (3) Replace if cracks and heavy wear are present. (4) Replace at first signs of fatigue or wear to prevent
damage to crankshaft.
LUBRICATION
Fill gear case with Mobilgear 630 or equivalent 80W90 oil to capacity listed in chart. Note oil level on oil dipstick, and maintain at this level.
NOTE: Slow speed operation of Myers Reciprocating Pumps can be accomplished by adding additional oil to the crankcase (see chart). The higher level compen­sates for lack of splash lubrication at slow speeds.
Some slight leakage may occur around crossheads and dipstick/vent area with additional oil.
For further information, please consult the factory.

The MoS2 fluid concentrate is marketed by Dow Corning, Phone (517)-496-6000 or www.molykote.com/iam under the designation “Molykote M Gear Guard.” Several other brands are available. Follow instructions of manufacturer.
SERVICE
CAUTION: Disengage clutch, disconnect electrical leads to motor, or remove spark plug leads on engine.
Following work on any internal pump parts, it is important to tighten all clamps, caps and assemblies to specific torque ratings, refer to Recommended Torque chart.
CAUTION: Also inspect cylinders for linear grooving by running your thumbnail circumferentially around bore of cylinder. If any grooving is detected also replace cylinders. New packing will rapidly cut or wear out in grooved cylinders.

ANT
from gear case (preferably drain at operating tempera­ture), replace plug and refill crankcase with new oil as above. Change oil every 300 hours thereafter. Check oil level daily and add oil as needed.
ADDITIVES FOR CRANKCASE OIL
Use of Molybdenum Disulfide (MoS2) is optional as an additive to the petroleum-based gear case oil in back geared pumps and speed reducers manufactured by Myers. Do not use this additive with synthetic oil. It appears to be so effective in reducing wear and friction that power train life may be doubled between overhauls.
REMOVING PACKiNG
Move assembly to front end of cylinder (top dead center). Remove valve assembly if required to provide clearance. Remove cap screw with an Allen wrench. (Allen wrench, Part No. 8574A11). Retract piston rod and insert tool as shown. Pull packing assembly out or push by rotating crankshaft by hand.

CAUTION: Also inspect cylinders for linear grooving by running your thumbnail circumferentially around bore of cylinder. If any grooving is detected also replace cylinders. New packing will rapidly cut or wear out in grooved cylinders.
INSTALLING PACKING
Assemble V-Rings onto stud as shown. Lubricate the outside of the assembly with Molykote or other grease for ease in insertion – do not use a graphite type grease. When installing each V-Ring assembly, rotate crankshaft until piston rod is at forward position. Place copper gasket 5030A128 in position in stud using a small amount of Permatex to hold in place. NOTE: Apply Loctite RC35 to capscrew prior to piston installation. Follow instructions on label and make certain threads in piston rod are clean and free of any grease or oil. Assemble capscrew, etc., into piston assembly and push into cylinder. Torque the capscrew to 50 ft. lb. using a hexagonlal socket attachment 3/8" across flats.
REMOVING CYLINDERS, (Fig. 5)
1. First remove packing as outlined previously.
2. Rotate crankshaft until piston rod is in rear position.
3. Insert puller (3) through inside of cylinder and pilot over
piston rod.
4. Insert disc (4) into slots on puller (3).
5. Slip plate (2) over threads on puller (3) as shown.
6. Screw nut (1) on thread on puller (3) and snug up.
7. Tighten nut (1) until liner breaks loose.
8. Loosen nut (1) and slip disc (4) out of slots.
9. Remove puller (3) and repeat to remove other
cylinders.
Reasonable care and judgment should be used when installing the new cylinder. Clean out any accumulation of loose rust or corrosion in cylinder body. Install a new O-ring in groove on tapered portion of cylinder, lubricate O-ring with oil or grease for ease in insertion. Position cylinder carefully by hand to avoid cutting the O-ring. Drive into position firmly with a wooden block and mallet. Never use a hydraulic press; excessive force can cause damage and make cylinders very difficult to remove for later replacement.
REMOVING SEATS: Wing Guided Valves
A. First remove valve caps, (61) and cylinder
caps, (72) which provide access to suction and discharge valves. Remove the stainless steel cage which serves as a valve guide and spring retainer. Remove cage (65), spring (66), and valve (67), from the pump fluid end. (Fig. 6)
. Suction valve seats are removed as above except
two stud lengths are joined using coupling
