INSTRUCTIONS
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 the tank or supply.
All pumps should be installed level. For mobile
applications the maximum angle of intermittent
operation should be no more than 5 degrees in any
one direction.
CALIFORNIA PROPOSITION 65 WARNING:
This product and related
accessories contain chemicals known to
the State of California to cause cancer, birth
defects or other reproductive harm.
It is recommended to install a pulsation dampener in
the discharge line to smooth out pressure pulse. This
can protect pump parts and piping for longer life and
quieter operation.
BELT DRIVE
With belt drives, the pulley on both the engines and
pump should be located as close as possible to the
bearing to reduce bearing and shaft bending loads.
Make sure that all bolts, nuts, set screws and keys are
properly tightened.
STARTING PUMP
Fill pump crankcase with recommended oil (SAE 30)
to the level mark on the oil saber. Replace all drain
plugs in pump and piping. Inspect tank to be sure
that no foreign material is in tank or suction line. 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 piston packing. Be sure that an operating
pressure gauge is located in discharge line. Use
a heavy duty, liquid filled, pulsation-free pressure
gauge. Make sure all valves, including spray gun or
nozzles, are open in discharge line. Spray gun may
be anchored to discharge back into tank. Completely
back off pressure adjusting device on the pressure
regulating valve. Check pressure rating for pulsation
dampener pressure regulator and pipe fitting to
make sure working pressure is not over maximum
pressure rating.
After starting, close discharge valve or spray gun
slowly while watching pressure gauge to make sure
relief valve or unloader is operating properly. Adjust
relief valve or unloader to desired pressure. Cycle
nozzles or gun on and off to be sure that pressure
adjustment and regulator operation is satisfactory.
Nozzle capacity should not exceed 90% of pump
capacity for satisfactory regulator operation. Avoid
freezing by draining all water from the pump and
system in cold weather. There is a 3/8 NPT drain plug
for each cylinder chamber.
SUGGESTED MAINTENANCE SCHEDULE
Check oil level – Daily
Drain and change oil (SAE 30) – 300 hrs.
Drain at operating temperature to prevent
contamination from settling.
Inspect piston packing and spacer rings – 500 hrs.
Inspect frequently for leakage; piston packing is
allowed to drip in order to cool and lubricate packing.
Replace if there is a stream leak.
Inspect valves and springs – 500 hrs.
Replace if cracks and heavy wear are present.
Inspect connecting link bearing inserts – 1000 hrs.
Replace at first signs of fatigue or wear to prevent
damage to crankshaft.
Inspect crankshaft tapered roller bearings and
piston stud – 2000 hrs.
Replace if there is any pitting on the seal surface or if
the surface is rough.
LUBRICATION
Pump – Fill crankcase with 2 qts of oil. Maintain oil
level between the high and the low level marks on
bayonet oil gauge inserted through the crankcase
cover. Add extra quart for crankshaft speeds under
300 rpm.
Drain oil from crankcase after first 30 hours of
operation. Refill with proper oil. Check oil levels
regularly. Change oil immediately if water droplets are
found on bayonet gauge.
SERVICE
Disconnect electrical leads to motor or remove spark
plug leads on engine before proceeding.
REMOVING PISTON
After removing the nuts, clamp and cylinder cap,
move piston assembly to the front end of the
cylinder. Remove valve assembly if required, to
provide clearance. Remove the cap screw and then
pull the piston assembly out, using a backward-
forward motion with the sliding handle bar against
the bolted-anchored end. Inspect cylinders for
linear grooving. If any grooving is detected, replace
cylinders. New packing will rapidly cut or wear out in
grooved cylinders.

4
INSTALLING CUP
Assemble the cup onto hub and lubricate the outside
of the assembly. When installing each cup assembly,
rotate the crankshaft until the piston rod is at the
forward position. Place the O-ring in position onto the
piston hub using a small amount of grease to hold in
place. Assemble capscrew into piston assembly and
push into cylinder.
REMOVING SEATS
Remove valve caps and cylinder caps, which provide
access to suction and discharge valves. Remove the
stainless steel cage which serves as a valve guide and
spring retainer. Remove cage, spring and valve from
the pump fluid end.
REPLACEMENT OF VALVES
Inspect tapered valve seat bore in fluid end for rust.
Place a new lower seat into the tapered hole. Drive
lower seat firmly into place. Repeat for the upper seat
and inspect the tapered bore for rust. Reassemble
the valve, spring and cage, and verify the springs are
in the correct location. When the upper and lower
valve seats are the same size, the heavier spring with
larger diameter wire is always installed on the upper or
discharge valve.
Be sure that cage is tightened onto valve seat.
Inspect seals on valve and cylinder caps. Replace
seals if signs of wear are present. Lubricate seals and
replace cap, bar and nuts. Torque cap cover’s nuts
to specification.
REPLACING CYLINDER LINERS
Remove piston packing and rotate crankshaft until
the piston rod is in rear position. Insert puller through
the inside of cylinder and insert disc into the slots on
the puller. Slip plate over the threads on the puller and
screw the nut on the thread in the puller. Tighten nut
until the liner breaks loose and then loosen nut and
slip disc out of slots. Remove puller and repeat to
remove remainder of cylinder liners.
Clean out any accumulation of loose rust or corrosion
in tapered cylinder. Inspect O-ring and replace it if
damaged. Insert liner into position by hand then firmly
drive in. Never use a hand or hydraulic arbor press as
it may shrink the liner.
REPLACING PISTON ROD SEALS
The rod seal assembly contains two seals and two oil
seals with lips facing power end. The oil seal can be
replaced without taking the fluid end off by removing
the cylinder and piston to allow access to the oil seal
housing. Unscrew Allen screws and place them into
the other two tapped holes. Gradually screw them
in to push the oil seal housing off the retainer. After
assembling new seals in the oil seal housing, an
assembly thimble should be used on the end of the
crosshead rod for sliding the oil seal housing back into
the retainer. Check gasket and replace if damaged.
An assembly thimble should be used on the small
end of the piston rod to expand the sealing edge
as it is pushed on. The thimble should be machined
from high carbon steel and polished on the exterior to
reduce the possibility of seal lip damage.
SERVICING CRANKCASE PARTS
To remove the crankshaft you do not need to remove
the cylinder body from the crankcase. Remove
the connecting link caps from the connecting links
and push the free links toward the cylinder end as
far as possible. Take off the bearing caps and pull
the crankshaft through the bearing opening. The
connecting links and link caps are mated to each
other and should be reinstalled in the same position
they were in before they were taken apart.
REPLACING CRANKSHAFT AND
SHIMMING BEARINGS
Remove bolts from both bearing caps. Carefully remove
bearing cap, shims and O-rings and discard shims and
O-rings. Inspect and clean shim surfaces on both bearing
caps and crankcase.
Slide crankshaft into the crankcase and rest bearings on
the sides of the crankcase. Place .045" shim on the drive
side bearing cap and place 4.38" O.D. O-ring onto the
bearing cap.
Cover key-way slot and slide the bearing cap with oil seal
over the drive shaft. Tighten the cap screws. Install the
non-drive side cap without shims or O-ring. Secure with
cap screws and tighten alternately so the crankshaft can
be fully rotated by hand to seat the tapered roller bearings.
Measure the shim gap adjacent to each of the screws
by inserting a flat feeler gauge in the gap until it bottoms
out. The required shim thickness for this cap is equal
to the average of the two gap measurements, plus
.005" constant.
Remove the two bolts and cap and place the correct shim
thickness on this cap. If the required shim thickness does
not match an .003" increment of a green shim, round up or
down to the nearest .003" shim increment.
Remove non-drive side bearing cap and place the 4.38"
O.D. O-ring on the cap and reinstall. Tighten the screws as
the crankshaft is fully rotated by hand to seat the bearings
and so no significant binding results.
SERVICING CONNECTING LINKS
When the connecting link bearings are worn, standard
replacement bearing inserts can be installed in the
connecting links. Do not change the size of the
bearing or the link by filing or grinding the faces.

5
When reinstalling the links on the crankshaft be sure
to place the oil holes upward for proper lubrication.

CROSSHEAD AND PISTON RODS
Repair parts for the crosshead and piston rod are
supplied as a complete unit. If either of these parts
becomes worn, it is necessary to replace both the
crosshead and piston rod. Under normal conditions
a crosshead will not wear, nor will the bore of the
crankcase wear, to the extent that replacement will be
required. A clearance of .002” to .004” is standard for
the crosshead.
RECONDITIONING CRANKSHAFTS
When crank pins are slightly damaged, they can
sometimes be reconditioned for further use. This can
be done with emery cloth and polishing, until all ridges
are completely removed. The final polishing operation
should be performed by using a very fine emery
cloth. This procedure can be followed only where
the amount of sanding does not reduce the normal
diameter of the crank pin.
Worn or corroded crank pins can be ground and
polished down to .030” under the size when the
cranks were new. The undersize bearing halves are
made especially for turned down crankshafts.
If the surface is badly damaged, the crankshaft can
often be salvaged by “metalizing” the crank pins,
regrinding and polishing to the original diameter.
When installing new bushings for the crosshead pin,
these bushings should be reamed to the proper size
after pressing into the link.
When assembling bearings on the crankshaft, an oil
seal expander thimble should be used at the end
of the shaft. A thimble of this type will cause the lip
of the oil seal to gradually expand up to the shaft
diameter allowing it to slip onto the shaft without
turning or damaging the seal in any way. A slight nick
or cut in the lip can damage a seal enough that it will
not retain the oil properly.
Warning – This pump must be installed with a
pressure relief valve in discharge line.

1. Pump priming is usually not necessary when the
pump is installed correctly. However, there are certain
conditions which may make it necessary to prime the
pump to get the pumping action started. Priming will
be required when it is impossible for the plunger to
displace the air in the pump and replace it with water.
This can be caused by a high suction lift, the valves
being stuck on the seat or by valves sticking due
to extreme corrosion. A pump will not prime readily
if someone has tampered with the valve springs
causing them to exert undue pressure of the valve
plates against the valve seats.
2. A gate valve is sometimes installed in the suction
line between a tank or pressure line and the pump
sediment chamber. It will shut off the supply source
in order to clean the sediment chamber or to perform
pump repairs. If this valve is partially or fully closed,
it will interfere with the flow of water to the pump
suction. This may cause severe knocking and
vibration of the pump because the water cannot flow
into the cylinder cavities fast enough.
3. A sediment chamber should be installed in the
suction line between the gate valve and the pump
suction. The strainers in the sediment chambers are
sufficient to allow a free flow of liquid to the pump.
If the strainers become severely clogged, they will
completely stop the flow of liquid to the pump.
4. Any plunger pump operating at a high pressure will
not perform properly nor quietly if a mixture of air and
water is allowed to enter the pump suction. A small
air leak in the suction line will cause the pump to
knock and vibrate excessively by allowing the pump
to draw a certain amount of water mixed with air on
each stroke of the piston. A large air leak will cause
the pump to lose prime after which it cannot be
reprimed until the air leak is stopped. Air leaks may
occur at the joints of the suction line piping, at the
gate valve in the suction line, at the gasket sealing
the cap on the sediment chamber, by a crack in the
suction wall of the cylinder body, or by air drawing
past the packing on the suction stroke if the packing
is badly worn.
Explanation of the Service Chart

5. If the pressure regulator internal bypass valve is
worn, it will allow too much of the pump capacity to
be bypassed and recirculated back to the tank. By
examining the flow from this valve with the discharge
turned on, it can be determined whether or not the
valve is worn. If a heavy flow continues when the
discharge is turned on, it is usually a good indication
of a worn valve and should be replaced.
6. Worn plunger cups, valves or valve seats will cause a
severe drop in pump capacity pressure. Worn
plunger cups are detected by water leakage past
the cups and should be replaced immediately. Water
getting into the pump crankcase will cause severe
corrosion of the bearings. Worn valves can only
be detected by visual examination of each valve
assembly. Abrasive liquid will cause wire cuts which
begin as a very small groove, but increase rapidly
once the valve starts to leak through this groove. If
the valve plates are replaced as soon as they start to
show this cutting action, it will prevent the valve seat
from becoming cut in a similar manner.
7. Pump cylinder bodies withstand an extreme amount
of shock and pulsation while in operation, but if the
pump is allowed to freeze, by not being drained, the
freezing may crack the cylinder body walls in almost
any location. If the crack occurs on the suction valve
or cylinder portion of the body, it may allow a small
amount of air to enter on the suction stroke and
cause noisy operation or a decrease in pumping
capacity. If the crack develops in the walls between
the cylinder cavities or discharge valve cavity, it
may allow the water to flow from one cavity to the
adjacent cavity and cause uneven displacement.
8. The holes in the gun or nozzle discs are continually
subject to wear because of the high velocity of the
liquid through the holes. If the holes become worn,
they may allow a higher rate of discharge than the
pump is able to provide, then a drop in pressure will
be noticed. This can quickly be checked by reducing
the number of nozzles or guns while watching the
amount of overflow from the pressure regulator. If
there is considerable overflow, it is an indication that
the regulator valve is worn rather than the gun or
nozzle disc.
9. Suction surge arresters should be installed on the
suction line of reciprocating pumps, 1-1/2" or 2"
can be used. A standing height of 12"-15" will be
sufficient with the top end closed by an ordinary
pipe cap.
10. Water may accumulate in the pump crankcase from
two sources; leakage of the plunger cups or an
accumulation of condensation/moisture inside the
crankcase due to changes in weather or the repeated
heating and cooling of the pump. Pumps used
consistently, running for a considerable period of
time to heat the oil and other working parts, will not
normally accumulate water by condensation. Replace
the plunger cups as soon as they start to leak.
11. Worn connecting link bearings are caused by
unusual or adverse operating conditions and are
seriously affected by corrosion if water is present
in the crankcase. They will wear out from overheating
if adequate oil is not provided in the crankcase. It
is recommended to drain, clean and refill with new
oil prior to any storage period. Replace bearings as
soon as any damage is discovered to avoid possible
damage to crankshaft.
12. Low oil in the crankcase can quickly cause failure
of the pump's power end and result in extensive
repairs. Oil level should be checked periodically
during normal operation and during all
maintenance work.
13. A foaming mixture will sometimes have the same
effect as a small air leak in the suction line. This is
because various quantities of the foam are drawn
through the suction line into the pump disrupting the
normal flow of water.
14. Pressure regulators and unloading valves may
become sluggish in action due to the plunger sticking
or fitting too tightly in its cylinder. This may happen
by an accumulation of chemicals collecting in and
around the plunger or due to excessive corrosion of
the plunger parts. To check this condition, remove
and clean the plunger and cover the parts with a
waterproof grease before assembling.
15. The stuffing box nut on the unloading valve lifting
post should not be tightened to severely grip or
bind the packing on the post. Tighten this nut just
enough to prevent leakage and chatter. The pressure
regulator and unloading valves may chatter or
vibrate excessively due to an unstable operation
from nozzling in the high or low capacity range of the
regulator or unloader. The range should be at least
50% to 90% of pump capacity. With unloader valves,
nozzle capacity should be at least 20% and not
exceed 90% of pump capacity.
16. If foreign matter becomes lodged between the pump
valve and valve seat, a drastic drop in capacity and
considerable surge or pulsation will occur in the
discharge line. Examine each valve if this occurs.
17. When a pump is used for a long period of time, a
waterlogged discharge surge could cause pulsation
at the discharge. The suction should be opened into
the atmosphere to allow air to be drawn through the
pump to recharge the surge arrester. Do this with the
pressure release valve open so the pump operates at
no pressure.

8
18. Noisy pump operation can be caused by a loose
plunger rod in the crosshead. This noise usually
has a regular cadence timed with each stroke of the
plunger. When this occurs, always replace both the
rod and the crosshead.
19. Increased preload to the crankshaft bearings will
reduce bearing life, require more power and generate
more heat, while insufficient preload may cause a
knock, timed with the crankshaft rotation. Check
for loose bolts on the crankshaft end caps or adjust
shims to obtain proper bearing preload.
