CLEAN AND INSPECT
WARNING
Cleaning solvents can be flammable and toxic
and can cause skin irritation.
When using
cleaning solvents, always follow the solvent
manufacturer’s recommended safety precau-
tions.
1.
Clean all the parts of the drive axle assembly
with solvent.
2.
Inspect the bearings and seals for damage.
3.
Inspect the drive axle shafts for wear and cracks
at the flange, shaft, and damaged splines. If axle
shafts show signs of wear or damage, replace the
axle shafts.
ASSEMBLE AND INSTALL

Sequence
NOTE:
Apply Loctite® 515 or High Performance RTV
Silicone Gasket Maker on the drive axle shaft flange
when installing.
3.
Install the back plates, hub/brake drum assem-
blies, and drive axle shafts. Refer to the section
Brake System 1800 SRM 1135.
4.
Connect slings and lifting device to drive axle.
NOTE:
When installing the drive axle, ensure the
drive axle is held with the upper surface of the drive
axle against the frame. This will prevent any gap be-
tween the frame and the drive axle mount, and will
ensure even weight bearing distribution.
5.
Position the drive axle in the lift truck.
NOTE:
It is recommended to use a torque multiplier
to achieve the torque specification in Step 6.
6.
Install four drive axle mounting capscrews and
nuts. Tighten capscrews to 245 to 270 N•m (181
to 199 lbf ft).
7.
Install universal joint to transmission using
two bolts. Tighten bolts to 30 to 37 N•m (22 to
27 lbf ft). See Figure 3.
8.
Install the isolators as shown in Figure 7.
