clean the groove, then apply a thin film of the
same lubricant used for the final drive gears
(Mobilith SHC 007 Synthetic Grease NLGI 00
or equivalent) to the v-ring seal.
Replacement
NOTE
Before installing the drive wheel assembly on
the truck, the outer drive pinion bearing, and
wheel bearings must be lubricated with
Mobilith SHC 220 Synthetic Grease NLGI 2 or
equivalent. Use a needle tipped grease gun to
lube the outer drive pinion bearing with this
same grease. Lubricate the final drive gears
with Mobilith SHC 007 Synthetic Grease NLGI
00 or equivalent.
NOTE
DO NOT remove the ring gear from the inside
of the drive wheel. The ring gear is not
available as a separate part. If the ring gear is
damaged, replace the drive wheel assembly.
1.
Pack both wheel bearings and place the inner
bearing on the spindle. Set the drive wheel
onto the spindle. Rotate the drive wheel so
the ring gear teeth mesh with the pinion gear
teeth, then push the drive wheel completely
onto the spindle.
2.
Install the outer bearing. Line up the inner tab
of a new lock washer with the slot in the
spindle and install.
3.
Carefully thread the lock nut onto the spindle
(beveled side toward the wheel). Seat the
bearings by tightening the nut to 60 lb-ft.
4.
Back the lock nut off until a tab of the lock
washer can be bent into the lock nut.
5.
Fasten the wheel cover onto the drive wheel.
6.
Lower the truck off the blocks or stands and
remove the rear wheel blocks. Connect the
battery and test drive the truck for proper
operation.
NOTE
If the wheel bearings are not properly
adjusted, the drive wheel may lock up in one
direction.
Changing Drive Tires
Special Tools:
Tire Changing Fixture (P/N
9650008), Tire Press (40 ton)
NOTE
There is a flange at the back of the drive wheel
that can be broken if the wheel is improperly
pressed.
1.
Remove the drive wheel assembly (refer to
procedure in this section).
2.
Place the larger ring of the tire changing
fixture on the press table. Place the wheel
and tire, ring gear down, on top of the ring,
making sure the ring does not touch the
wheel. Center the smaller ring on top of the
wheel. Press the wheel out of the tire.
NOTE
When replacing the drive tire, make sure the
composition and size are such that
maneuverability and capacity are maintained.
3.
Place the new tire on the press table. Align
the wheel on top of the tire with the ring gear
up. Press the wheel into the tire.
4.
Install the drive wheel assembly.
