4. Install the pressure seals, flat side outward, into the
grooves in the wear plates. Follow by carefully placing
the backup gaskets, flat side outward, between the
pressure seals and the grooves in the wear plate.
5. Apply a light coating of petroleum jelly to the exposed
side of the front flange.
6. Lubricate the drive gear shaft with clean hydraulic oil.
Insert the drive end of the drive shaft through the wear
plate with the pressure seal side down and the open side
of the pressure seal pointing to the inlet side of the motor.
Carefully install shaft into front flange.
7. Lubricate the idler gear shaft with clean hydraulic oil.
Install idler gear shaft into the remaining position in the
front wear plate. Apply a light coating of clean hydraulic
oil to gear faces.
8. Install rear wear 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--
rings and O--ring grooves in the body. Install new O--
rings to the body.
10.Install locating dowels in body. Align marker line on
the body and front flange.
IMPORTANT: Do not dislodge seals during installation.
11.Gently slide the body onto the assembly. Firm hand
pressure should be sufficient to engage the dowels.
12.Install the four (4) cap screws with washers and hand
tighten.
IMPORTANT: Prevent damage when clamping the
fan 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 33 ft -lb (45
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.
