Remove Transfer Case from
Vehicle
WARNING
To prevent serious eye injury, always wear safe eye
protection when doing maintenance or service.
WARNING
The proportional differential eliminates dead engine
holding ability if one end of the vehicle
is raised without air pressure applied to the
differential lockout. Serious personal injury can
occur.
WARNING
Support the vehicle with safety stands. Do not
work under a vehicle only supported by jacks.
Jacks can slip or fall over and cause serious
personal injury.
1. Make sure the vehicle is on a level surface.
2. Put blocks under the wheels not being raised to
keep the vehicle from moving.
3. Raise the vehicle so that the area to be serviced
is off the ground. Support the vehicle with safety
stands.
4. Remove the drain plug from the bottom of the
transfer case and the Proportional Differential
(if equipped). Drain the lubricant from the transfer
case. See page 8.
Also remove the drain plug from the bottom of the
differential, if used, to drain the oil from the
differential. See page 8.
5. Disconnect the drivelines from the input and output
yokes or flanges of the transfer case.
6. Disconnect the brake actuator linkage from the
parking brake.
7. Disconnect the air line to the differential lockout or
the declutch/PTO.
8. Disconnect the harness for the indicator switch wires.
9. Use a hydraulic roller jack to support the transfer
case. Remove the mounting bolts that hold the case
to the vehicle.
10. Carefully remove the transfer case with the
hydraulic jack.
11. Steam clean the outside of the transfer case to
remove heavy amounts of dirt.
NOTE:
Close or cover all openings before steam cleaning.
These openings include the breather and oil/level
drain.
12. Attach angle iron brackets with bolts in the
mounting holes of the brake half of the transfer
case housing. Figure 6.
13. For a transfer case without lifting loops, install
eyebolts in the mounting holes in the other half of
the transfer case housing. The eye bolts permit
easier lifting of the transfer case.
WARNING
To avoid serious personal injury and possible
damage to components, be very careful when
using lifting devices.
•
Inspect to make sure that the lifting loops or
lifting straps are not damaged.
•
Always use both lifting loops and lifting straps
when lifting.
•
Do not subject lifting loops or lifting straps to
any shock or drop loading.
14. Use a lifting device attached to the lifting loops or
eye bolts to lift the transfer case. Use the angle iron
brackets to mount the case in the repair stand.
