6.3.3 Transfer Case Removal
1. Level the vehicle, ground the carriage, place the
travel select lever in NEUTRAL (N), engage the
parking brake switch and shut the engine OFF. Allow
the engine to cool.
2. Remove the engine mount rear cover plate (Fig. 6–2).
3. Unbolt and remove the two M8 bolts securing the
bulkhead fitting bracket to the transfer case. Safely
swing the bracket and the hydraulic hoses out of the
way to help prevent interference with removing the
transfer case and drive shafts. Reinstall the bolts
securing the left side of the center transfer case
cover plate to the transfer case.
Figure 6–2. Transfer case mounting arrangement.
IMPORTANT: To help ensure optimum performance, the
drive shaft assemblies are specially balanced as a unit at
the factory. When servicing any flange yoke, slip yoke, or
drive shaft tube, order a complete assembly if components
are bent or damaged. Refer to the
Sky Trak International
Model 3606 Parts Manual
for ordering information.
4. For reference, mark the transmission input drive shaft
and flange yoke at the transfer case for return to their
original positions upon reinstallation (Fig. 6–3).
Unbolt the flange yokes from the transmission and
from the transfer box. Move the drive shaft out of the
way to allow clearance for transfer case removal.
Figure 6–3. Mark the shafts and yokes for return to their
original positions.
5. For reference, mark the front and rear axle output
drive shafts and transfer case for return to their
original positions upon reinstallation (Fig. 6–3).
Unbolt the flange yokes from the axles and from the
transfer box. Move the drive shaft out of the way to
allow clearance for transfer case removal.
6. Position a transmission jack or suitable lifting device
beneath the transfer case. Operate the jack to
contact and support the transfer case, but DO NOT
jack up or raise the transfer case itself. Secure the
transfer case to the jack or lifting device with a sling.
7. Unbolt the M16 bolts and lock washers (Fig. 6–2)
securing the transfer case to the vehicle chassis.
Carefully lower the transfer case and remove it from
beneath the vehicle.
