Planetary Drive Removal (Fig. 4)
1. Park machine on a level surface, stop engine, en-
gage parking brake and remove key from the ignition
switch.
2. Drain the oil from the brake assembly and the Plane-
tary drive; refer to the traction unit Operator’s Manual.
CAUTION
Before removing wheels or performing other
service, make sure machine is parked on a sol-
id, level surface such as a concrete floor. Al-
ways chock or block wheels. Use jack stands or
other appropriate load holding devices to sup-
port the raised machine. If the machine is not
properly supported, the machine may move or
fall, which may result in personal injury.
3. Chock rear wheels and jack up front of machine (see
Jacking Instructions in Chapter 1 − Safety in this manu-
al). Support machine with jack stands.
4. Remove front wheel assembly.
5. Support wheel motor and brake assembly to prevent
them from shifting during planetary removal.
NOTE: The wheel motor and brake assembly fasteners
thread into the planetary housing, and must be removed
prior to removing the planetary drive from the machine.
6. Remove two (2) cap screws and flat washers that se-
cure wheel motor to planetary assembly. Check condi-
tion of O − ring (item 17) and replace if necessary (see
wheel motors in Chapter 5 − Hydraulic System in this
manual).
7. Remove four (4) flange head screws that secure
brake assembly to planetary assembly (see Brake As-
sembly in this chapter). Remove and discard gasket
(item 12).
8. Support planetary assembly to prevent it from falling.
Loosen and remove six (6) flange head screws that se-
cure planetary assembly to frame. Remove planetary
assembly from machine.
Planetary Drive Installation (Fig. 4)
1. Position planetary assembly to machine making
sure to engage splined brake shaft with planetary drive
shaft. Secure planetary assembly to frame with six (6)
flange head screws.
For OPH − 2 series planetary drives: tighten screws to
60 ft − lb (81 N − m) .
For VA02 series planetary drives: tighten screws
from 75 to 85 ft − lb (101 to 115 N − m) .
2. Make sure that gasket surfaces of planetary and
brake assembly are clean.
3. Make sure gasket (item 12) is properly aligned and
secure brake assembly to planetary (see Brake Assem-
bly in this section of this chapter).
For OPH − 2 series planetary drives: tighten screws to
60 ft − lb (81 N − m)
.
For VA02 series planetary drives: tighten screws
from 75 to 85 ft − lb (101 to 115 N − m) .
4. Make sure wheel motor O − ring (item 17) is in position
and secure wheel motor to planetary with two (2) cap
screws and flat washers.
For OPH − 2 series planetary drives: tighten screws
from 60 ft − lb (81 N − m) .
For VA02 series planetary drives: tighten screws
from 75 to 85 ft − lb (101 to 115 N − m) .
5. Install wheel assembly.
6. Fill planetary drive with gear lube; refer to traction
unit Operator’s Manual. A portion of the gear lube will
pass into the brake assembly automatically.
7. Test planetary drive operation.
8. Check and adjust brake cables for proper brake op-
eration (see machine Operator’s Manual).
Failure to maintain proper wheel lug nut torque
could result in failure or loss of wheel and may
result in personal injury.
WARNING
9. Remove jack stands and lower machine to ground.
Tighten wheel lug nuts in a crossing pattern from 85 to
100 ft − lb (116 to 135 N − m) .
