Disassembly
Cleanliness is extremely important when repairing a hydraulic motor.
Work in a clean area. Before disconnecting the lines, clean port area of
motor thoroughly. Use a wire brush to remove foreign material and
debris from exterior joints of motor. Check shaft and keyway, use 600
grit paper/cloth to remove all nicks, burrs, and sharp edges that might
damage the shaft seals when installing retainer on shaft and bearing
assembly. Before starting disassembly procedures, drain oil from
inside of motor.

1 Place motor in a vise with output shaft down. Clamp across edge
of bearing housing not on housing (see Figure 1). Excessive clamping
pressure on housing will cause distortion. When clamping, use some
protective device on vise, such as special soft jaws, pieces of hard
rubber or board.

Reassembly
Check all mating surfaces. Replace any parts that have scratches or
burrs that couId cause leakage. Clean all metal parts in clean solvent.
Blow dry with air. Do not wipe with cloth or paper towel because lint
or other matter could get into the hydraulic system and cause damage.
Do not use a coarse grit papers/cloth or try to file or grind motor parts.
Check around the keyway and chamfered area of the shaft for burrs,
nicks, or sharp edges that can damage the seals when reassembling
the retainer.
Note: Lubricate all seals (prior to installation) with petroleum jelly
such as Vaseline®. Use new seals when reassembling the motor.
Refer to parts list (6-127 6000 Series -005 and 6-159 6000 Series 006) for replacement parts and proper kit number.
21 Install shaft and bearing assembly in bearing housing (see Figure
12). Do not damage seal in bore of housing. You may need a press to
install shaft and bearing assembly.

23 Install 92,3 [3.64] I.D. seal, back-up ring and shaft seal in retainer.
Flat or smooth side of shaft seal must face toward retainer as shown in
Figure 14. Apply petroleum jelly to inside diameter of shaft seal (after
installing seal).
24 Before installing retainer, place a protective sleeve of bullet (see
note below) over shaft. Grease inside diameter of dust and shaft seals.
To prevent damage to seals, install retainer over shaft with a twisting
motion. Do not cut or distort shaft seal. Damage to shaft seal will
cause external leakage.

33 Align case drain hole and pressure relief hole in Geroler with case
drain hole and pressure relief hole in bearing housing. Install Geroler
on bearing housing (see Figure 17). Retain rollers in outer Geroler
ring if they are loose.
34 Install valve drive in Geroler.
35 Apply a light film of petroleum jelly on 95,0 mm [3.74 inch] I.D.
seal. Install seal in valve plate.

27 Reposition motor in vise with output shaft down. Clamp across
edges of retainer as shown in Figure 16.
28 Pour a small amount of light oil inside the output shaft.
29 Install 2 studs (earlier models), diagonally opposed, in bolt holes of
bearing housing (see Figure 16). If you replace studs with bolts, use 2
studs for alignment purposes when stacking parts.
30 Apply a light film of petroleum jelly on 95,0 mm [3.74 inch] I.D.
seal. Install seal in bearing housing (see Figure 16).
31 Install drive in output shaft (insert longer splined end of drive first),
(see parts drawing on page 3).
32 Apply petroleum jelly on 2 seals, 6,1 mm [.24 inch] I.D. Install seals
(1 on each side of Geroler) in case drain grooves of Geroler.
36 Align case drain hole in valve plate with case drain hole in Geroler.
Install valve plate (seal side toward Geroler) on Geroler as shown in
Figure 17.
Timing Step No. 2 — Locate slot opening in valve plate which is in
line with largest open pocket of Geroler (see Figure 17).
37 Use the following procedure for installing the valve on the valve
plate.
Timing Step No. 3 — Locate any one of the side openings of the valve
that goes through to the face of the valve. Line up this side opening
in the valve with open slot of valve plate that is in line with largest
open pocket of Geroler. Rotate valve clockwise (1/2 spIine tooth) to
engage valve with the valve drive spline, alignment reference shown in
Figure 17 (above). This procedure provides standard timing when
pressurized as shown in Figure 18 (below) .

This motor is the same as the standard without the shaft/bearing

the bearing housing (see Figure 26). Follow same disassembly and
reassembly procedures as rear section of standard motor.
Important: Loctite® information for bearingless motor below.
Drive
Seal
Seal
Figure 26
Important: This motor requires Loctite in threaded holes of
mounting flange.
Follow these procedures:
Adequate Loctite penetration and sealing depend highly on cleanliness
and dryness of threads. Use a non-petroleum base solvent to clean
excess oil from threads of flange after disassembly. You may need to
use a tap to clean threads of excess old Loctite. Then, after you have
fully reassembled the motor, apply 2 to 3 drops of Loctite no. 290 at
top of threaded holes (see Figure 27).
Note: Allow Loctite 5 minutes for thread penetration before installing
motor on gear case.
Attention:
Do not use more
than 3 drops of
Loctite on
threaded portion.
