Disassembly
Step 1
Cleanliness is extremely
important when repairing
hydraulic motors. Work in a
clean area. Before disconnecting
the hydraulic motor, thoroughly
clean the exterior. emove
motor from application and
drain the oil from the motor
before disassembly.
Importa t Note: All seals
should be replaced when the
motor is disassembled. Front
shell bearing should be replaced
only when shaft is to be
removed.
Step 2
emove the seven bolts and
disassemble the motor in a
vertical position as shown. As
the dowel pins are glued in dur-
ing assembly, they may or may
not come loose.
Step 3
Examine condition of bearing
in the valve plate. eplace the
bearing only if signs of wear
and/or contamination are visible.
If necessary remove the bearing
from valve plate by tapping it
with a hammer and a screwdriver.

Disassembly
Step 4
emove grease seal by wedg-
ing it out with a screwdriver.
emove the shell bearing by
prying the bearing cage open.
emove the rollers and insert
key (.25” key stock, 2.2” long,
45° recess) horizontally in
between the races. Press the
key to remove the bearing from
the housing.
Step 5
Insert flat point of a modified
cotter pin puller (with tip ground
to a flat point) between housing
and brass backup. Wiggle up
and down to begin to dislodge
the seal and work the point
deeper in. Work all the way
round the seal. Some locations
work better than others, some
seals come out easier than
others.
Step 6
Check all mating surfaces. To
reduce the chance of leakage,
replace any parts that have
scratches or burrs. Wash all
metal parts in clean solvent.
Blow them dry with pressurized
air. Do not wipe parts dry with
paper towels or cloth, as lint in
a hydraulic system will cause
damage.

Step 1
Position the housing in the
vertical position on a clean
smooth surface, use shell bearing
tool No. 606253 and press the
shell bearing into position in the
housing. The lettering on the
bearing race denotes the side
to be contacted by the tool.
Step 2
Lubricate the grease seal with
Mobilux EP 111 and press it into
position in the housing with tool
No. 606254.
Step 3
Flip housing. Install back-up
washer into interior bore of the
housing. Lubricate the shaft
seal lip with Mobilux EP 111,
place on assembly tool No.
600421-2 and press it into the
interior bore of the housing.

Step 4
Place a bearing race, then a
thrust bearing, and then the
second bearing race into interior
bore of the housing. Place shaft
bullet No. 606256 over output
end of shaft and install into the
bearing housing.
Step 5
Install four dowel pins into the
blind holes on the balancing
ring using sufficient Loctite 277
to hold the pins. Install one
backup ring, then the o-ring
onto the balance ring. Install
the wave spring with sufficient
petroleum jelly to keep it in
place.

Step 6
Install the second backup ring
into the housing. Invert the
balance ring and place into the
housing making sure to align
the dowel pins with the holes
in the housing.
Importa t Note: Press on the
balance ring and verify that it
springs back when released.
This ensures that the ring has
not been pinched.
Step 7
Install the valve into the housing
with the shaft notch lining up
with the longest tang of the
valve. Insert button end of the
drive into the shaft and mark
the spline tooth that lines up
with the notch in the shaft. This
marked tooth is critical in the
timing of the motor.

Step 8
Insert the thrust bushing in the
valve plate aligning its tabs.
Press bearing into valve plate
with Tool No. 606252 with the
lettering on the bearing contacting
the tool. Place valve plate
assembly into the housing
aligning the bolt holes.

Install two greased seals into
the Geroler®. Install the
Geroler®onto the drive with
splined end away from the
housing. Align star according to
rotation preference as outlined
in the timing procedure. Timing
procedure is given below.
a. Sta dard Timi g
Align the marked spline of the
drive with star tip. This pro-
duces CCW rotation when the
A port is pressurized.
b. Reverse Timi g
Align the marked spline of the
drive with star valley. This pro-
duces CW rotation when the A
port is pressurized.
