SPECIFICA
TIONS
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.

OR SHAFT
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.

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.

: After first 30 hours of operation drain oil
IMPORT
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
