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 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.
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.
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 selfpriming 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.
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 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
-5-
L-1526 (12/12, Rev. B)
Plumbing Installation
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.
hydraulic motor are sized to accommodate 1/2” NPT fittings
on the pressure port and 3/4” NPT on the tank port. For
maximum performance, the hydraulic lines should also be at
least 1/2” [12.7 mm] in size for the pressure line and 3/4”
[19.05 mm] for the tank line.
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 flow- compensated
(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
putting the pressure line to the Pressure Port Adapter and
return line to the Tank Port Adapter. The adapters on the

Adjusting Centrifugal Pump Output
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.
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.
L-1526 (12/12, Rev. B)

Closed Center (Load Sensing) — All Models
Many tractors are being introduced with load sensing
systems (also referred to as flow and pressure- compensated
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 pressure- compensated 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.

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”

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.
7. Install the o-ring on the mounting flange. Replace the
o-ring if worn or damaged.
Seal Replacement/Pump Housing Reassembly
8. Place the pump casing on the mounting flange, insert
and tighten the bolts.

1. Lubricate the seal cavity in the Mounting Flange with
WD-40®, LPS or equivalent. Do not lubricate the shaft.
The work area and motor should be as clean as
possible to prevent contamination of parts.
2. Install the stationary portion of the Mechanical Seal by
sliding over the Shaft with the ceramic side out.
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
L-1526 (12/12, Rev. B)
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.
3. 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).
4. Inspect the sealing area of the shaft for wear. Inspect
other Shaft Assembly Components for wear and replace
if necessary.
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.
Figure 13
5. While motor is completely disassembled, clean all parts
in a solvent bath.
Build Shaft Sub-Assembly
To Remove the Shaft Assembly from the Motor Body
1. Remove the Slinger Ring from the Motor 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.
1. To assemble the seal cartridge, remove the old
seal from the cartridge by pressing it out. The cartridge is reused by assembling the new seal into cartridge, ensuring the new seal is pressed in with the lip
seal on the opposite side as shown in Fig.A.
Press
2. Using the large retaining ring pliers, remove the Retaining
Ring next to the Ball Bearing in the Motor Body.
Seal Spacer
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.
Cartridge
Seal
Fig. A
Important: To prevent damage to the seal lip extending out, use seal spacer as shown to guard lip during assembly.
2. Install the large retaining ring onto large diameter end of shaft.
3. From the small, threaded end of the shaft, install the
following parts in this order: thrust bearing race, thrust bearing, 2nd thrust bearing race.
Note: The thrust bearing and races should not be reused if they are showing any signs of wear.
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).
L-1526 (12/12, Rev. B)
4. Install new type seal spacer­(looks like a thick washer,
approx .130 inch thick).
5. Before installing the new seal, its lip must be expanded to
fit on the shaft. With the seal lip facing out, slide the seal
over the threaded end of the shaft and gently push the seal
onto the raised area of the shaft. Do not push the seal past
the large retaining ring groove on the shaft.
-10-
6. Once the seal has been expanded, remove the seal from
the shaft.
7. Install seal cartridge assembly: With seal lip facing the
large end of the shaft, slide the seal cartridge assembly over the threaded end of the shaft and gently push into the
raised area of the shaft. Align the seal lip to enter
the center diameter of the seal spacer and push until seal
body touches seal spacer.
Figure 15
Important: If the seal lip is longer than the seal spacer’s
width, please stop the assembly and review parts being used.
3. Turn the motor body assembly over (threaded shaft end
down) on the arbor press. Press the shaft down into
its “final position” until the small retaining ring can be
installed in the shaft next to the ball bearing.
8. Assemble two o-rings on the outside body of the new seal
cartridge assembly as shown in Fig B. Install o-rings one at
a time and do not roll over each other.
4. Install small retaining ring on shaft.­
(2) O-rings
5. Check shaft rotation at this point. It should rotate
smoothly with only slight resistance from the seal lip
pressure on the shaft. If you feel any gritty or sticking movement, return assembly to the arbor press
and lightly press on the threaded end of the shaft to
relieve press fit compression on the thrust bearing. Note: Don’t over do this press. The objective is
to move the small outer retaining ring installed in the
previous step back to ”touching only” the ball bearing
inner race.
Fig. B
Shaft
9. Finished shaft sub-assembly should look like this:
Important: If gritty or sticky movement persists, it’s likely due to re-used parts or the body needle bearing is in need of replacement.
­­Reassembly of Remaining Hydraulic Motor Parts
10.Do not press, but place the shaft sub-assembly into the
motor body with threaded end of shaft up. Lubricate the
two o-rings with hydraulic or mineral oil before assembling.
1. Place Motor Body in a vise with large end of shaft facing
up.
2. Install the o-ring in the body.
3. Install the Roll Pin on the shaft. Place the Inner Gear of
the Gerotor onto the shaft making sure Gerotor slot lines
up with the key in the shaft.
The Roll Pin can slide up behind the inner gear of the
gerotor when the gear is installed. Make sure the key is
visible in the slot after the gear is in place.
Figure 14
4. Install the outer portion of the Gerotor, making sure the
Gerotor is centered within the o-ring groove on the body.
Install Shaft Sub-Assembly Into Motor Body
Important: Make sure the surface edge of the arbor press
fixture is smooth and clean. An unthreaded piece of
pipe (1” x 4” high) is needed to support the outer race of
the seal cartridge sub-assembly and outer race of the
ball bearing during assembly. Place this pipe over the
shaft threaded end for assembly of the following steps.
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, the Outer Gerotor, and Gerotor Housing with
hydraulic oil or mineral oil.
1. Place the body on a support fixture in the arbor press.
Using an unthreaded piece of pipe (1” dia. x 4” high),
press the shaft subassembly down into the body until it
bottoms out. This is a light press fit and should be done
slow and easy.
Special attention should be exercised when working with
retaining rings. Always wear safety goggles when working with spring or tension-loaded fasteners or devices.
7. Install o-ring on the motor end plate.
2. Install the new ball bearing onto the threaded end of
the shaft. Press down using the 1” x 4” pipe until the
retaining ring can be installed in its groove in the bearing core of the motor body. Install the retaining ring.
8. Place end plate on gerotor housing, making sure holes in
end plate line up with pins in the gerotor housing.
-11-
L-1526 (12/12, Rev. B)
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.
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.)
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.
13.Remove Hydraulic Motor from the vise. Turn shaft by
hand to check for binding.
14. Install Slinger Ring over Motor Shaft.
15. Install Motor into Pump Mounting Flange. Insert four Hex
Head Bolts; then alternately and evenly tighten them.
[For polypropylene models, secure the Hydraulic Motor
to the Mounting Flange with four Hex Head Cap Screws
and Nuts. The nuts should be visible when the assembly
is complete.]
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.)

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:
