1. Verify the elevation of the sun gear (9) and coupler
(102) on the motor shaft to be as shown in Fig. 7,
page 12 (or use dimensions obtained prior to
removal, as suggested on page 12, in step 5a).
2. Clean and repack the gear carrier (1) and gear
housing (21) with new grease (see Gear Carrier
Lubrication, page 13), if this has not been done.
3. Mount the motor onto the gear carrier (1), aligning
the sun gear (9) so that the sun gear meshes with
the “planet” gears in the gear carrier assembly.
4. Align the motor, rotating the shaft as necessary,
and bolt the motor to the gear housing (21) and
bearing housing (36), using the socket head cap
screws (60) and washers (61). Alternately tighten
the cap screws to 9 ft-lb (12 N-m).
NOTE: For best results, apply lubricant, such as
grease or anti-seize compound, to screws when re-
assembling.
This completes the motor replacement. To reinstall the
agitator, refer to the Installation instructions.

Hydraulic Motor Replacement
1. Make sure power is disconnected from the unit
(see Power Connection ).
PRESSURIZED FLUID HAZARD
To reduce the risk of serious injury, such
as fluid injection or splashing fluid in the
eyes or on the skin, follow the Hydraulic
Pressure Relief Procedure on page 9.
WARNING
2. Remove the agitator (see Agitator and Shaft
Removal), and place on a clean level surface
capable of supporting its weight.
3. Remove the four socket head cap screws (60) and
washers (61) holding the motor adapter (131) to
the bearing housing (36).
4. Carefully lift the motor adapter off the bearing
housing. It may be necessary to gently tap the
bearing housing to separate it from the adapter.
5. Inspect O-ring (43) and replace if necessary.
6. Loosen the set screws for the coupling half (103)
and insert (105) and remove from the motor shaft.
7. Loosen the machine screws (130) holding the
motor to the motor adapter, and remove the motor
from the adapter.
NOTE: If you intend to replace the bearing assembly,
see Bearing Assembly Replacement on this page at
this point and then continue this procedure.
8. Unpack the new motor.
9. Install the motor onto the motor adapter (131), and
tighten the machine screws (130) to secure the
motor to the motor adapter.
NOTE: For best results, apply lubricant, such as
grease or anti-seize compound, to screws when re-
assembling.
10. Install the motor coupling half and insert removed
from the old motor onto the new motor shaft.
11. Position the motor adapter on the bearing housing
(36), aligning the coupling halves of the motor
shaft and bearing housing as necessary, so the
two halves mesh.
12. With the motor adapter in place on the bearing
housing, install the washers (61) and four socket
head cap screws (60) to secure the motor to the
bearing housing.
This completes the motor replacement. To reinstall the
agitator, refer to the Installation instructions.

Bearing Assembly Replacement
This procedure assumes the motor has been removed
(see steps 1–7 Hydraulic Motor Replacement). See
Fig. 10 for this procedure.
1. Loosen and remove the socket head cap screws
(70) and lock washers (72) holding the bearing
housing to the flange.
2. Remove the bearing housing (36) from the flange
(75) as an assembly.
3. Unpack the new bearing housing assembly, being
very careful not to alter the orientation and align-
ment of the components.
4. Place the new bearing housing onto the flange,
and secure tightly in place with the socket head
cap screws (70) and lock washers (72).
NOTE: For best results, apply lubricant, such as
grease or anti-seize compound, to screws when re-
assembling.
5. Continue with step 8 of the Hydraulic Motor
Replacement procedure, or with step 11, if a new
motor is not being installed.
