Disassembly
1. Cleanliness is extremely important when repairing
hydraulic motors. Work in a clean area. Before disconnect-
ing the hydraulic motor thoroughly clean the exterior.
Remove motor from application and drain the oil from
the motor before disassembly.
2. Remove the 9 cap screws and disassemble the motor
in the vertical position as shown in Figure 1.
Note placement of small ball checks in Geroler.
3. Remove shuttle valve (and relief valve if applicable)
from end cap.
4. Remove two plugs from end cap (end ported motors only).
5. Check all mating surfaces.To reduce the chance of leak-
age, 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.
Tools Required
– 1/4 inch Hex Key
– 3/16 inch Hex Key
– 5/8 inch Hex Key (End Ported Motor Only)
– Torque wrench - 200 Nm [150 lb-ft] capacity

Reassembly
Note:Always use new seals when reassembling hydraulic motors.
Refer to parts list for seal kit number and replacement parts.
Important: During reassembly, lubricate the new seals with
a petroleum jelly such as Vaseline®
. Also lubricate machined sur-
faces with clean hydraulic fluid.
6. Install one poppet, spring and dash pot into shuttle valve
bore from valve plate side of end cap.
7. Install non-threaded plug with o-ring into end cap shuttle
valve bore. O-ring and plug are to be lightly coated with
petroleum jelly to ease assembly and plug should be
inserted flush with end cap mounting surface.
8. Install shuttle piston from opposite end of shuttle valve
cavity.
9. Install one shuttle valve poppet, spring and dash pot
onto piston.
10. Install one shuttle valve threaded internal hex plug with
o-ring. Shuttle plug threads may have light coat of oil or
preservative.Torque plug to 37-45 Nm [324-396 lb-in].
11. For a motor with low pressure relief valve, install poppet,
shims, spring and plug. Plug threads may have light coat
of oil or preservative.Torque plug to 18-22 Nm [162-198
lb-in].
12. For a motor without low pressure relief valve, install plug
with o-ring and torque plug to 18-22 Nm [162-198 lb-in].

Flange Assembly
13. Position flange on work bench
with the o-ring grooves face
down and install face seal (72,9
[2.87] OD).
14. With mounting flange o-rings
grooves up, install two o-ring
seals (150,8 [5.94] ID & 107,7
[4.24] ID) into flange. Install back
up-up ring (69,5 [2.74] OD) over
o-ring (63,2 [2.49] ID) with flat
side up (See Figure 3). Back-up
ring and o-rings may be greased to
assist in retaining parts.
Final Assembly
15. Place drive into build fixture.
Place mounting flange (seal
grooves up) over drive.
16. Place Belleville spring (concave
side down) in groove in mount-
ing flange.
17. Place outer and inner balance
plates on mounting flange. Align
shuttle flow cavity of outer bal-
ance plate with shuttle flow cavi-
ty of mounting flange.
18. Install two steel balls into seats
of star (one per seat). Retain
balls with grease.
19. Install o-ring seals (150,8 [5.94]
ID) in o-ring grooves on both
sides of Geroler. Seal on balance
ring side of Geroler must have
sufficient coating of petroleum
jelly to assist in retaining seal in
the groove. Place Geroler assem-
bly over outer balance plate.
Make sure that balls are in their
seats. Align shuttle flow cavity of
Geroler with shuttle flow cavity of
outer balance plate.
20. Place valve plate onto Geroler.
Align bolt holes and shuttle flow
hole with mating holes on
Geroler.
21. Place end cap on workbench
name plate side down, seal
grooves face up. Install o-rings
(150,8 [5.94] ID & 26,7 [1.05] ID)
into seal grooves. Seals must
have sufficient coating of petro-
leum jelly to assist in retaining
seal in the groove. Figure 5

22. Carefully invert end cap and
place onto valve plate. Make
sure that shuttle flow cavities
are aligned.
23. Install nine cap screws lubricat-
ed with DTE-26/DTE-24. Pre-
torque each in a crisscross pat-
tern to 80±10 lb-ft. Finally, in a
crisscross pattern, tighten
screws to 135±5 lb-ft].
Note: Damage to the balance plate will
occur if these bearingless motors are
lifted by the drive.
