General Information—Hydraulic Systems
Hydraulic Pumps
Gerotor-Type
Hydraulic Motor
Hydraulic pumps come in two basic types:
•
•
Constant displacement - which will continue to put
out its rated flow regardless of pressure, until the
relief valve bypasses the flow.
Variable displacement - which will produce only
the flow needed by the implement until the total
pump output is reached. If less than the full pump
output is required, an automatic stroke control
mechanism decreases the pump output to maintain
a constant pressure and flow. The output varies
according to demand.
Figure 3
Three Systems
Fitting these components together and installing a motor, we
have one of the three types of systems: Open Center,
Closed Center (pressure compensated) and Closed Center
Load Sensing (flow and pressure compensated).
Open Center
Spool Valve
In Neutral
Position
Open Center Systems
In an Open Center System, the hydraulic pump puts out a
constant flow. If the pump puts out more oil than the motor
can use, a portion of the oil must be bypassed around the
motor. When the oil is bypassed around a loop and does no
work, the energy put into it by the pump turns into heat.
Therefore, the amount of oil bypassed should be kept to a
minimum. Use the largest motor possible.
Figure 1
Spool Valves
There are two basic types of spool valves used in
conjunction with these pumps — Open and Closed Center.
In the Open Center Valve (See Figure 1), the flow goes
straight through the valve when in the neutral position. This
type is used for constant displacement pumps where the
flow should never be shut off.
Closed Center (Pressure-Compensated) Systems
The Closed Center Pressure-Compensated system has a
variable displacement pump which will deliver flow at the
necessary rate to maintain a specified pressure. It is
desirable to equip implements with a motor of a low flow
range that will cause the pump to operate between 1800
and 2100 psi [124 and 145 BAR]. A motor that requires a
large volume to obtain the correct implement speed usually
causes the hydraulic pump in a closed center system to
operate at a lower pressure than desirable. This low
pressure results in unnecessary flow and the generation of
heat that lowers the lubricating quality of the oil and may
damage transmission parts. Use the smallest motor
possible.
Closed Center
Spool Valve
In Neutral
Position
Closed Center Load Sensing Systems
(Flow and Pressure-Compensating)
Figure 2
The Closed Center Valve (See Figure 2) is used with
variable displacement pumps. The flow is completely shut
off in the neutral position, causing the pump stroke to adjust
to zero flow. The flow stops, but the pump maintains a static
pressure up to the valve.
The Closed Center Flow-Compensated System is a
variation of the pressure-compensated system, designed
primarily for more efficient operation and the generation of
less heat. It works on the principle of maintaining a constant
pressure drop from the pump to the work port of the selector
valve. Any variation in demand at the motor will cause a
change in flow. The system senses this change in flow due
to the change in pressure drop across the valve and causes
the pump to compensate by varying the pump flow. No
restrictor is used in the pressure line and no oil is bypassed.
Hydraulic Motors
Figure 3 shows an internal gear motor (Gerotor) where
pressure causes the cavities between the gears to expand
on one side, developing torque. The Gerotor type of
hydraulic motor is used on Hypro pumps for its superior
performance characteristics, including cooler running and
higher rpm capabilities.

Installation Instructions
Priming the Pump
All Models — Open Center Systems
Models include Tank Port Adapter with built-in Check Valve
Assembly and Pressure Port Adapter.
The pump must not be run dry.
Before starting the pump, the inlet line and pump must be
filled with liquid and all discharge lines must be open. On
self-priming models, only the pump chamber needs to be
filled with liquid. The pump must not be run unless it is
completely filled with liquid because there is a danger of
damaging the mechanical seal, which depends on the liquid
for its lubrication.
Non-self-priming models should be mounted below the level
of the liquid. The suction line should slope down to the
pump and be free of dips and bends. If this cannot be done,
a foot valve should be installed in the end of the inlet line so
that the line can be completely filled with liquid before
starting the pump.
For best priming results, the top vent plug should be
removed from the pump casing. A vent line (1/4" [6.35
mm] tubing is sufficient) should be installed running
back to the top of the tank. This line prevents air lock and
allows the pump to prime itself by bleeding off trapped air.
The small stream of liquid that returns to the tank during
operation is negligible. The discharge from this line should be
positioned in the tank above the high liquid level. Self-priming
models can be primed by removing the top vent plug and
filling the priming chamber. The priming chamber will fill to
the level of the inlet port. After use, the priming chamber
should be flushed and drained to avoid chemical corrosion
and damage from freezing. Drain by removing the lower
drain plug.
HM2C and HM4C Models Only — Closed Center and
Small Open Center Systems.
Models include Tank Port Adapter with built-in Check Valve
Assembly and Pressure Port Adapter with three different
size metering orifices for HM4C models. The orifices are not
required for use with closed center systems with flow
control, such as John Deere closed center systems. Also, do
not use for small open center systems with a maximum flow
of 8 gpm [30.28 lpm] for HM2C model; 10 gpm [37.85 lpm]
for HM4C model. If necessary, the pressure port adapter
may be used without a metering orifice installed in any
closed center system. For best results, the pressure
differential across the motor should be less than 2500 psi
(170 bar).
Preliminary to Mounting
Consult the owners manual to determine the type and
capacity of the hydraulic system. Make sure the hydraulic
system is recommended to operate with a continuous load.
Refer to the Pump Selection Guide to confirm you have the
proper pump for your hydraulic system.
Check to see that the pump impeller can be turned by hand.
(Turn the shaft clockwise using a deep socket wrench on
the impeller nut.) If it cannot be turned, open the pump
casing to look for obstructions. Clean out any corrosion build
up where the casing fits over the eye of the impeller.
Pump Inlet Line
To achieve full capacity from the pump, the inlet line
should be at least the same size as the inlet port on the
pump. Reducing this line size will restrict the capabilities of
the pump. The line must also be free of air leaks. Check all
fittings and connections in the suction line for tightness.
The introduction of air may affect the priming and pumping
capabilities of the pump. Use good quality suction hose
that will not be collapsed by suction.
For non self-priming models, the centrifugal pump should
be mounted below the liquid level and as near to the liquid
source as possible to allow for the shortest suction line
practical. To achieve optimal performance, the suction line
should slope down into the pump. Avoid rises and humps
that could trap air in the line to the pump. The suction line
and pump should be filled with liquid prior to starting the
pump, and all discharge lines should be open.
Controlling the Pump Flow
The best way to control the flow is by incorporating two
control valves in a pipe tee immediately after the strainer in
the discharge line. This permits controlling agitation flow
independently of nozzle flow.
In any centrifugal pump, it is the large volume of liquid which
puts load on the drive. Use only the flow needed to develop
the pressure required at the boom and to maintain adequate
agitation. Hydraulic motor-driven centrifugal pumps are
easily adjusted to the exact flow required, as explained in
the Operating Instructions of this manual.
Centrifugal Pump Control
Hypro now offers many different components for spraying
systems. The Hypro centrifugal pump control incorporates
the electric flow control valve, a self-cleaning line strainer,
a visual pressure gauge and a manual agitation control
valve.
Pump Outlet Line
The recommended orientation for the outlet port is pointing
straight up. This allows liquid to stay in the pump while it is
priming. The outlet line should be the same size as the
pressure port on the pump to give the optimal flow. The
line should have as few restrictions and elbows as
possible to optimize the pump performance and reduce
pressure drop from the pump to the spray tips.
Flow Control Valve
A high-flow electric proportional valve allows for maximum
flow control to the boom valves. It provides smooth, rapid
control that can be controlled from either an electronic rate
controller or switch box.
-5-
Strainers
The recommended placement of the strainer for a
centrifugal pump is in the pump outlet line. This will
eliminate any possible restriction that the strainer could
Plumbing Installation
create if it were installed in the inlet line. Ensure that the
proper strainer size and screen mesh are used to limit the
pressure drop and achieve the best filtration. Line strainers
can also be installed in the tank fill line to filter liquid as it is
loaded into the tank as well as in the boom lines to further
filter the solution prior to the spray tips. Tank baskets can
also be used to filter material added through the tank lid.
putting the pressure line to the Pressure Port Adapter and
return line to the Tank Port Adapter. The port adapters on
the hydraulic motor are sized to accommodate 1/2" NPT
fittings. For maximum performance, the hydraulic lines
should also be at least 1/2" [12.7 mm] in size. For lines
longer than 8 feet [2.44 m] or for the HM3C models,
hydraulic line size should be at least 3/4" [19.05 mm] in
order to reduce heat generation.
The tank (OUT) port adapter with a built-in check valve
assembly will guard against reverse operation — allowing
you to reverse oil flow to operate other equipment. This
adapter must not be removed. On HM2C and HM4C
model pumps, the pressure (IN) port adapter is a two-piece
assembly consisting of an open (unrestricted) adapter with
three orifices packed loose with the pump. (See the
Operations Section.)
When using the HM2C or HM4C unit on any flowcompensated (load sensing) closed center system, or any
small open center system with a maximum flow of 8 gpm
[30.28 lpm] for HM2C or 10 gpm [37.85 lpm] for HM4C, the
metering orifice should be removed from the pressure port
adapter. When using these units on flow-compensated
systems, connect to the motor priority circuit if your tractor has
one.
Standard spool valves, which are found on all tractor
hydraulic systems, may cause potentially damaging high
peak pressures in the hydraulic system when closed
because of abrupt shut-off of oil flow in both the supply and
return lines. When shutting off the pump, move the selector
to the FLOAT position to allow the centrifugal pump to come
to a stop gradually.
Agitation
The centrifugal pump control contains a manual agitation
control valve that can be adjusted to provide the right
amount of flow to the jet agitators in the tank to ensure
proper mixing within the tank.
Flowmeter
To eliminate the mechanical problems of a turbine
flowmeter, we recommend that an electromagnetic
flowmeter be used. These flowmeters have no moving
parts to wear out and will provide a more consistent and
accurate flow reading. They can be input into just about
any electronic rate controller or switch box.
Boom Section Valves
For rapid response and reliability, we recommend electric
plunger valves be used for boom control. The valves
should be sized accordingly to minimize the pressure drop
and maximize the flow rate. The boom tubing or hose
should be sized accordingly to ensure that a pressure drop
in the lines does not occur, causing inconsistent pressures
at the nozzles.
Nozzle Bodies
Nozzle bodies with shut-off check valves are
recommended to eliminate dripping from the spray tips
when the boom valves are shut down.

Hooking Up the Hydraulic Motor to the
Tractor Hydraulic System
Hypro Series 9300HMC hydraulic motor-driven pumps can
be mounted on either the tractor or sprayer. When hooking
up, make sure that no dirt or liquid gets into the hydraulic
motor. Keep all hydraulic connections clean. Be sure to
connect the hydraulic motor into the system correctly by
Operation
3. Prime the centrifugal pump with all valves open (See
the Installation Instructions and System Configuration
Diagram).
4. Close the agitation line valve and keep the control valve
and the boom shut-off valve open. Note the spray
pressure.
5. Open the agitation line valve until you have desired
circulation in the tank. Recheck the spray pressure. If it
is too low, close down the agitation line valve until the
desired spray pressure is reached. If the spray pressure
is too high, throttle the centrifugal pump by closing down
the control valve.
Open Center Systems— All Models
Adjusting Centrifugal Pump Output
HM1C, HM3C & HM5C motors have bypass screw fully
closed from the factory. HM2C & HM4C motors have
bypass screw set at 1-1/2 turns from fully closed from the
factory.
1. Open the bypass adjustment screw 2-1/2 turns from
fully closed. Turn the bypass screw in to achieve the
flow for the desired gpm and psi.
2. Start the tractor. Leave the directional valve in the
neutral position and allow hydraulic oil to circulate for
approximately 10 to 15 minutes or until adequately
warmed.
-6-
Closed Center (Load Sensing) — All Models
Many tractors are being introduced with load sensing
systems (also referred to as flow and pressurecompensated systems) which simplify system setup and
eliminate many of the problems associated with using the
wrong size pump motors on a given hydraulic system.
Usually, any of Hypro’s 9300HMC models may be used on
this type of system, provided the hydraulic system produces
sufficient oil flow for the hydraulic motor being used (Refer
to the Pump Selection Guide).
This system maintains a constant flow of hydraulic oil for a
given pressure drop. The flow is adjustable with a flow
control valve installed in the hydraulic system (such as the
Tortoise/Hare control on John Deere tractors). Because this
system has adjustable flow, there is no need to bypass
hydraulic oil as in an open center system, or to restrict the
flow with orifices as in a closed center pressurecompensated system.
Closed Center (Pressure-Compensated) —
HM2C and HM4C Models Only
On a pressure-compensated system, the amount of oil that
is allowed to flow through the hydraulic motor is regulated
by a metering orifice in the pressure port adapter. Three
different sizes of orifices are supplied with the HM2C and
HM4C model pumps to allow flexibility in the flow required
for individual sprayer needs.
The smaller the orifice, the less hydraulic oil goes through
the motor, so the pump will run slower and the flow of liquid
pumped and the spray pressure will also be less. As the
hydraulic oil flow is increased (by installing a larger orifice),
the amount of liquid being pumped and the spray pressure
is also increased.
Installing and Removing Metering Orifice
1. Shut off the hydraulic system.
2. Disconnect the line to the pressure port of the hydraulic
motor.
3. Remove the adapter from the motor using a 1-1/16''
wrench. Make sure the o-ring is on the metering orifice
before installing into port adapter.
4. The orifice is removed or installed in the port adapter by
tapping either in or out of the adapter.
A. To remove — tap the orifice out from the small end
of the adapter.
B. To install — tap the orifice in from the large end of
the adapter. The orifice is seated when a snap
sound is heard.
Adjusting Centrifugal Pump Output
1. Make sure the orifice from the pressure port adapter of
the hydraulic motor has been removed (HM2C and
HM4C models only).
2. Close and lock down the bypass adjusting screw in the
hydraulic motor.
3. Set the tractor hydraulic flow control valve for minimum
hydraulic oil flow to the remote outlet (Tortoise position).
4. Start the tractor and allow the hydraulic oil to circulate
for approximately 10 to 15 minutes or until adequately
warmed.
5. Prime the centrifugal pump with all valves open (See
the Installation Instructions and System Configuration
Diagram).
6. Close the agitation line valve and open the control valve
and the boom shut-off valve.
7. Slowly adjust the tractor hydraulic flow control valve until
the desired boom pressure is attained.
8. Open the agitation line valve until sufficient agitation is
observed. If spray pressure drops, readjust the tractor
hydraulic flow control valve to restore it to the desired
pressure.
Adjusting Centrifugal Pump Output
1. Open the bypass adjusting screw in the hydraulic motor
three (3) turns.
2. Start the tractor and allow the hydraulic oil to circulate
for approximately 10 to 15 minutes or until adequately
warmed.
3. Close and lock down the bypass adjusting screw in the
hydraulic motor.
4. Prime the centrifugal pump with all valves open (See
Installation Instructions and System Configuration
Diagram).
5. Close the agitation line valve and the control valve;
open the boom shut-off valve.
6. With the pump running, open the control valve until the
pressure gauge indicates the desired spraying
pressure.
7. Open the agitation line valve until sufficient agitation is
observed. Then, if spray pressure drops, readjust the
control valve to restore to the desired pressure.
8. If a sufficient boom pressure cannot be attained, install
the #2 size orifice and repeat Steps 5 through 7.
9. If a sufficient boom pressure still cannot be attained with
the #2 size orifice, install the #3 size orifice and repeat
Steps 5 through 7.
10. If a sufficient boom pressure still cannot be attained
with the #3 size orifice, remove the orifice and repeat
Steps 5 through 7.
Flush Pump After Use
One of the most common causes for faulty pump
performance is gumming or corrosion inside the pump.
Flush the pump and entire system with a solution that will
chemically neutralize the liquid pumped. Mix this solution
according to the manufacturer’s directions. This will dissolve
most residue remaining in the pump, leaving the inside of
the pump clean for the next use.
To Prevent Corrosion
After cleaning the pump as directed above, flush it with a
permanent-type automobile antifreeze (Prestone®, Zerex®,
etc.) containing a rust inhibitor. Use a 50% solution, half
antifreeze and half water. A protective coating will remain on
the inner pump surfaces. Save the excess antifreeze for the
next application. Plug the ports to keep out air during
storage. For short periods of idleness, noncorrosive liquids
may be left in the pump, but air must be kept out. Plug the
ports or the seal port connections.

Pump Housing Disassembly
Instructions in italics describe procedures for the
Series 9300P Polypropylene Centrifugal Pumps, when
different than the cast iron pumps.
Pump Seal Removal
1. Lightly lubricate the Shaft for easier removal of the Seal.
Using two screwdrivers positioned opposite each other,
pry the rotary portion of the Seal from the Shaft (See
Figure 8).
1. Using a 9/16" box end wrench, remove the four Hex
Head Bolts holding the Pump Casing to the Mounting
Flange. (If necessary, tap Pump Casing Outlet Port with
rubber mallet or hammer to separate.) [Using a 1/2"
wrench, remove the six bolts from the front. For the two
bottom bolts securing the base, you will need to hold the
two nuts with another 1/2" wrench. Also remove the
5/16" screw from the rear near the outlet port.]
2. To remove the Impeller Nut, insert a large screwdriver or
file (at least 10" [254 mm] long) into Impeller Vanes to
prevent Impeller from turning when loosening nut. Use a
5/8" socket wrench to remove the Impeller Nut by
turning it counterclockwise (See Figure 6). [Use 7/8"
deep socket wrench to remove Plastic Seal Nut, then
9/16" deep socket to remove Metal Jam Nut and
Washer.]
Figure 8
In the case of a severe pump seal leak, inspect the
Shaft/Bearing Assembly in the hydraulic motor for
possible contamination.
Figure 6
2. Using a 1/2'' box end wrench, remove the four bolts
holding the Motor to the Mounting Flange. Remove
Motor. [Remove the Plastic Back Cover flange. Knock
the Seal out from back with a hammer and screwdriver.
Use a 1/2'' socket wrench and 1/2'' box end wrench to
remove the Mounting Flange from the Hydraulic Motor.]
Figure 7
-8-
3. Using a screwdriver and hammer, tap out the stationary
portion of the Mechanical Seal from the motor side of
the Mounting Flange. (If the motor is not removed, the
seal can be pried out with a small screwdriver.)
The threads of the Plastic Seal Nut are fine and can be
easily cross threaded. To prevent cross threading, turn
the Plastic Seal Nut counterclockwise until area of
thread engagement is detected; then turn the Plastic
Seal Nut clockwise until it is secure. Do not over tighten
the Plastic Seal Nut.
The seal will be damaged by removal in this manner. A
new seal must be used when pump is reassembled.
6. Insert a Woodruff Key into the Shaft key slot; then place
the Impeller on the Shaft and align it with the Key and
press against the Mechanical Seal Assembly. Apply a
blue thread locking compound to the Impeller Nut, and
using a 5/8'' socket wrench and using a screwdriver to
hold the Impeller, install the Impeller Nut. [On
polypropylene models, insert the Woodruff Key into the
Shaft key slot. Place the Impeller on the Shaft and align
it with the Key; then press against the Mechanical Seal
Assembly. Place the Metal Seal Washer on the Shaft.
Apply a drop of blue thread locking compound on the
Impeller Nut and secure the Impeller to the Shaft as
described previously.]
Clean-Up Of Pump Housing
1. Using a circular bottle-type wire brush with air or hand
drill, clean the Outlet Port, Inlet Port and the sealing
areas of the o-ring on the Pump Casing and Mounting
Flange. Using the port brush, clean the seal cavity in the
Mounting Flange. [The last step should not be
performed on the 9300P.]
2. After wire brush cleaning, it is recommended that the
Pump Casing and Mounting Flange be further cleaned
in a solvent tank to remove rust and corrosion particles.
Seal Replacement/Pump Housing Reassembly
7. Install the o-ring on the mounting flange. Replace the
o-ring if worn or damaged.
8. Place the pump casing on the mounting flange, insert
and tighten the bolts.
If the hydraulic motor requires repair, proceed to
Disassembly and Repair of the Hydraulic Motor.
Disassembly and Repair of the Hydraulic Motor
1. Lubricate the seal cavity in the Mounting Flange with
WD-40®, LPS or equivalent. Do not lubricate the shaft.
2. Install the stationary portion of the Mechanical Seal by
sliding over the Shaft with the ceramic side out.
The work area and motor should be as clean as
possible to prevent contamination of parts.
Make sure both the seal cavity and seal are clean and
lubricated.
3. To seat the seal in the seal cavity, use a piece of 3/4"
PVC pipe 4" to 6" [101.6 to 152.4 mm] in length.
Lubricate sealing surface on seal after it is seated. Do
not lubricate the shaft.

6. If Motor End Plate will not lift off easily, use a small
screwdriver to carefully pry apart the boss portion of the
End Plate and Gerotor Housing until free (See Figure
11). If Gerotor Housing will not lift off easily, carefully pry
apart the boss area between the Gerotor Housing and
the Motor Body. (It may be necessary to alternate sides
when prying apart Motor sections.)
Hydraulic Motor Shaft Disassembly and Repair
1. Remove Large Retaining Ring from Shaft with a
screwdriver. Remove Thrust Bearing Assembly from
Shaft (includes the Thrust Bearing and two Thrust
Bearing Races) and the Seal Spacer.
2. Remove the Small Retaining Ring next to the Shaft Ball
Bearing.

Figure 11
7. Remove both parts of the Gerotor.
8. On HM3C models, remove the Woodruff Key from the
Shaft. On HM1C, HM2C and HM4C models, remove
the Roll Pin from the Shaft.
To remove the Bearing from the shaft, place the shaft
(threaded end up) in the arbor press fixture. Place the two
support bars provided in the repair kit opposite each other
and between the seal on the shaft and the arbor press
fixture. Using an arbor press, press the shaft through the
Bearing, Seal Spacer and Seal (See Figure 13).
9. Remove the o-ring from the Motor End Plate and Body
with a flat instrument such as a knife blade.
10. Inspect Motor End Plate, Body and Gerotor Housing for
wear and/or gouging. If gouging has occurred in both
the Motor End Plate and Body, the motor is not
repairable. If gouging has occurred in the Motor End
Plate, Body or Gerotor Housing, the part that is worn
must be replaced. If Gerotor Housing is damaged,
Gerotor parts must also be replaced.
4. Inspect the sealing area of the shaft for wear. Inspect
other Shaft Assembly Components for wear and replace
if necessary.
5. While motor is completely disassembled, clean all parts
in a solvent bath.
To Remove the Shaft Assembly from the Motor Body
1. Remove the Slinger Ring from the Motor Shaft.
To Install New Shaft Seal
1. The sealing lips on a new seal must be expanded to fit
on the shaft. Press seal onto large end of shaft with seal
lip facing out. Do not push seal past keyway on shaft.
Special attention should be exercised when working
with retaining rings. Always wear safety goggles when
working with spring or tension loaded fasteners or
devices.
2. Once seal lip has been expanded, remove the seal from
the shaft.
2. Using the large retaining ring pliers, remove the Retaining
Ring next to the Ball Bearing in the Motor Body.
If bearing is binding against the retaining ring so that it
cannot easily be removed, place the motor body
(threaded portion of the shaft up) on arbor press. Using
a piece of un-threaded metal pipe (1" dia. x 4" high [254.
mm x 101.6 mm high]), slide over the shaft and gently
press down with the arbor press just enough to relieve
the pressure on the retaining ring.
3. With the seal lip facing the large end of the shaft, slide
the seal over the threaded end of shaft and gently push
onto the raised area of the shaft, stopping
approximately 1/4" [6.35 mm] from the Large Retaining
Ring groove.
4. Over the large end of the shaft, install the Seal Spacer,
Thrust Bearing Race, Thrust Bearing, second Thrust
Bearing Race and the Large Retaining Ring.
To Install Shaft Bearing
1. Over the threaded end of the shaft, install the Spacer
Ring and the Ball Bearing.
2. Insert the shaft (threaded end down) into the arbor
press fixture. Place the two support bars opposite each
other and between the bearing and the fixture. Place on
an arbor press and carefully press the shaft down,
allowing just enough room for the retaining ring next to
the bearing to be installed.
Figure 12
3. Place body in position on arbor press. Threaded portion
of the Shaft should be inside the fixture. Press out shaft
assembly with arbor press (See Figure 12).
Figure 13
-10-
4. Install the outer portion of the Gerotor, making sure the
Gerotor is centered within the o-ring groove on the
body.
Make sure the spacer ring between the seal and bearing
is free floating (not binding).
Should the main needle bearings in the hydraulic motor
need replacement, a new body and/or end plate with the
main bearing already installed, must be used. If this
occurs, check other internal parts of the motor for
damage and wear.
To Install the Shaft Assembly in the Motor Body
5. Install the Gerotor Housing, making sure the pins in the
Gerotor Housing line up with their respective holes in
the body.
6. Lightly lubricate the area between the Inner and Outer
Gerotor and the Outer Gerotor and Gerotor Housing
with hydraulic oil or mineral oil.
Special attention should be exercised when working
with retaining rings. Always wear safety goggles when
working with spring or tension-loaded fasteners or
devices.
1. Place the Shaft Assembly into the Motor Body bearing
bore with threaded end up (See Figure 14).
7. Install o-ring on the motor end plate.
8. Place end plate on gerotor housing, making sure holes
in end plate line up with pins in the gerotor housing.
9. Install four Socket Head Cap Screws in Motor End
Plate, and using a 1/4" Allen wrench, tighten Cap
Screws alternately and evenly in a crisscross pattern to
approximately 15 foot pounds [ 20 Nm] of torque.
Figure 14
2. On arbor press, place Body on arbor press fixture.
Make sure the surface edge of the fixture is smooth and
clean.
An un-threaded piece of pipe (1" dia. x 4" [25.4 mm x
101.6 mm] high) is needed to support the outer bearing
race on the shaft ball bearing. Place this pipe over the
shaft and press shaft assembly down until retaining
ring can be installed in its groove in the bearing core of
the motor body (Figure 15).
10. Install the Thread Seal Gasket on the Bypass Adjusting
Screw. Put the Gasket on from the slotted end and turn
until four threads on the screw are showing. Install the
Washer and the Nut. Install Bypass Adjusting Screw in
the motor end plate.
A. For closed center hydraulic systems, turn the
Bypass Adjusting Screw in until it bottoms out in the
End Plate. Tighten nut down with 9/16" box end
wrench.
B. For open center hydraulic systems, turn the Bypass
Adjusting Screw in until it bottoms out in the End
Plate; then turn back out 11⁄2 full turns. Holding the
Bypass Adjusting Screw with a screwdriver, tighten
Nut. (Motor will then have to be readjusted to tractor
system.)
11. Replace o-ring on both port adapters.
12. Install Pressure Port Adapter and Tank Port Adapter
back onto the motor. (For ease of installation, tighten
the Pressure Port Adapter first, then the Tank Port
Adapter.)

Limited Warranty on Hypro/SHURflo Agricultural Pumps & Accessories
Hypro/SHURflo (hereafter, “Hypro”) agricultural products are warranted to be free of defects in material and workmanship under
normal use for the time periods listed below, with proof of purchase.
- Pumps: one (1) year from the date of manufacture, or one (1) year of use. This limited warranty will not
exceed two (2) years, in any event.
- Accessories: ninety (90) days of use.
This limited warranty will not apply to products that were improperly installed, misapplied, damaged, altered, or incompatible with
fluids or components not manufactured by Hypro. All warranty considerations are governed by Hypro’s written return policy.
Hypro’s obligation under this limited warranty policy is limited to the repair or replacement of the product. All returns will be tested
per Hypro’s factory criteria. Products found not defective (under the terms of this limited warranty) are subject to charges paid by the
returnee for the testing and packaging of “tested good” non-warranty returns.
No credit or labor allowances will be given for products returned as defective. Warranty replacement will be shipped on a freight allowed
basis. Hypro reserves the right to choose the method of transportation.
This limited warranty is in lieu of all other warranties, expressed or implied, and no other person is authorized to give any other
warranty or assume obligation or liability on Hypro’s behalf. Hypro shall not be liable for any labor, damage or other expense, nor shall
Hypro be liable for any indirect, incidental or consequential damages of any kind incurred by the reason of the use or sale of
any defective product. This limited warranty covers agricultural products distributed within the United States of America. Other world market
areas should consult with the actual distributor for any deviation from this document.
Return Procedures
All products must be flushed of any chemical (ref. OSHA section 1910.1200 (d) (e) (f) (g) (h)) and hazardous chemicals must be
labeled/tagged before being shipped* to Hypro for service or warranty consideration. Hypro reserves the right to request a Material Safety
Data Sheet from the returnee for any pump/product it deems necessary. Hypro reserves the right to “disposition as scrap” products returned
which contain unknown fluids. Hypro reserves the right to charge the returnee for any and all costs incurred for chemical testing, and proper
disposal of components containing unknown fluids. Hypro requests this in order to protect the environment and personnel from the hazards
of handling unknown fluids.
Be prepared to give Hypro full details of the problem, including the model number, date of purchase, and from whom you purchased your
product. Hypro may request additional information, and may require a sketch to illustrate the problem.
Contact Hypro Service Department at 800-468-3428 to receive a Return Merchandise Authorization number (RMA#).
Returns are to be shipped with the RMA number clearly marked on the outside of the package. Hypro shall not be liable for freight damage
incurred during shipping. Please package all returns carefully. All products returned for warranty work should be sent shipping charges
prepaid to:

For technical or application assistance, call the Hypro Technical/Application number: 800-445-8360. To obtain service or warranty
assistance, call the Hypro Service and Warranty number: 800-468-3428; or send a fax to the Hypro Service and Warranty FAX:
651-766-6618.
*Carriers, including U.S.P.S., airlines, UPS, ground freight, etc., require specific identification of any hazardous material being shipped. Failure to do so may
result in a substantial fine and/or prison term. Check with your shipping company for specific instructions.
Note: This warranty does not apply to Hypro Pump Kit Model 1538,
1551, 1538-SP and 1551-SP. This is because the user could incorrectly
assemble the parts and cause the pump to work improperly.
