Power Train Disassembly & Assembly
Disassemble the Brake
To disassemble the brake, refer to the brake section
of this manual.
NOTE : If it is necessary to drive out the anchor pins
with a mallet and brass drift, remove the brake dust
shields for proper access to the anchor pins.
Remove the Spindle and Brake
Spider
To prevent serious personal injury and possible
damage to components, be very careful when
using lifting devices during service and
maintenance procedures.
•
Inspect to make sure that neither lifting strap is
damaged.
•
Do not subject lifting straps to any shock or drop
loading.
Removal of the capscrews allows the spindle and
brake assembly to separate. They can fall from the
planetary axle housing and cause damage to
components and serious personal injury.
1. To prevent the spindle (30) and the brake spider
from falling after all the mounting capscrews (31)
are removed, use one of the following procedures:
a. Use a lifting device to support the spindle during
disassembly.
b. Remove only two capscrews. Replace them
with two temporary 0.75 inch-10 UNC thread
studs 4 inches (102 mm) long before the
remaining capscrews are removed.
– Install one stud at the 11 o’clock position.
– Install one stud at the one o’clock position.
2. Remove the two capscrews and washers that
mount the clamp around the brake camshaft
housing tube to the axle housing.
3. Remove the capscrews (31) and washers (32) that
mount the brake spider and spindle (30) to the
axle housing.
4. Remove the brake spider and air chamber
assembly from the spindle (30).
5. Remove the spindle (30) from the axle housing. If
necessary, tap lightly on the spindle to loosen the
pilot fit and to overcome the adhesion due to cured
gasket material in the flange joint.
