Assembly (Fig. 59)
NOTE: When assembling the motor, check the marker
line on each part to make sure the parts are properly
aligned during assembly.
1. Lubricate O--rings, pressure seals, back--up seals
and thrust plate grooves with a thin coat of petroleum jel-
ly. Lubricate all other internal parts freely with clean hy-
draulic oil.
2. Install new seals into front cover (Fig. 61):
A. Press shaft seal into front cover until it reaches
the bottom of the bore.
B. Install back--up washer into front cover and then
install retaining ring into the groove of the front cover.
Make sure that retaining ring is fully seated in front
cover groove.
C. Install new dust seal into front cover.
3. Place front cover, seal side down, on a flat surface.
4. Install the pressure seals, flat side outward, into the
grooves in the thrust plates. Follow by carefully placing
the back--up seals, flat side outward, between the pres-
sure seals and the grooves in the thrust plate.
5. Apply a light coating of petroleum jelly to the exposed
side of the front cover.
6. Lubricate the drive gear shaft with clean hydraulic oil.
Insert the drive end of the drive shaft through the thrust
plate with the pressure seal side down and the open side
of the pressure seal pointing to the inlet side of the mo-
tor. Carefully install shaft into front cover.
Hydraulic System
7. Lubricate the idler gear shaft with clean hydraulic oil.
Install idler gear shaft into the remaining position in the
front thrust plate. Apply a light coating of clean hydraulic
oil to gear faces.
8. Install rear thrust plate with pressure seal side up and
open side of the pressure seal pointing to the inlet side
of the motor.
9. Apply a light coating of petroleum jelly to new O--ring
and O--ring groove in the body. Install new O--ring to the
body.
10.Install locating dowel pins in body. Align marker line
on the body and front cover.
IMPORTANT: Do not dislodge seals during installa-
tion.
11. Gently slide the body onto the assembly. Firm hand
pressure should be sufficient to engage the dowel pins.
12.Install the four (4) socket head screws with washers
and hand tighten screws.
IMPORTANT: Prevent damage when clamping the
motor into a vise; clamp on the front flange only.
Also, use a vise with soft jaws.
13.Place front flange of the motor into a vise with soft
jaws and alternately torque the cap screws 18 ft- -lb (25
N- -m).
14.Remove motor from vise.
15.Place a small amount of clean hydraulic oil in the inlet
of the motor and rotate the drive shaft away from the inlet
one revolution. If any binding is noted, disassemble the
motor and check for assembly problems.
