1. Make sure that all parts of the final drive are thoroughly clean and free of dirt and debris
prior to assembly. Check the condition of all O-ring seals that are used in the final drive. If
any of the seals are damaged, use new parts for replacement. Reassemble the final drive on
Tooling (A).
1/17(W)w

Note: New final drives are equipped with angular contact ball bearings.
2. Apply Tooling (H) to the surfaces inside sprocket housing (35) that contacts the bearing
cups. Install a bearing cup that is in each side of the sprocket housing with a press. Make
sure that the bearing cups are properly seated.
3. Apply Tooling (H) to the surfaces inside the sprocket housing that contacts bearing cones
(44).

2/17(W)w

6. Adjust the bearing preload of the final drive. Determine the correct number of shims (40)
that are required for the proper bearing preload, as follows:
Note: New final drives are equipped with angular contact ball bearings that require pre-load
like the old roller bearings.
a. Use a depth micrometer to measure the step height of coupling gear (38) at several
locations around the gear. Find the average for the measured dimensions around the
gear and record the dimension. Call this Dimension (X).
b. Apply a load of 4000 kg (8820 lb) to the bearing cones.
c. Rotate sprocket housing (35) several times to seat the bearing cones.
d. Reduce the load to 1000 ± 100 kg (2205 ± 220 lb).
3/17(W)w

e. With the bearing cones loaded, measure the distance between the top face of the
motor housing and the top face of the bearing cone. Take measurements in several
locations around the motor housing. Find the average of the measured dimensions,
and record the dimensions. Call this Dimension (Y).
f. Determine the correct thickness of the shims which are used between the bearing
cones and the coupling gear . Use the following equation to determine the shim pack
thickness.
Shim pack thickness ... (Y) − (X) ± 0.05 mm (0.002 inch)
Note: If two shims are required, install the thinnest shim next to the coupling gear
during final assembly.
7. Attach Tooling (F) and a suitable lifting device to sprocket housing (35). Separate sprocket
housing (35) from the motor housing.
Reference: Refer to Disassembly and Assembly, "Duo-Cone Conventional Seals - Install".
Note: The rubber seals and all surfaces that contacts the seals must be clean and dry. After
installation of the seals, put clean SAE 30 oil on the contact surfaces of the metal seals.

the locating pins in the motor housing.
11. Make sure that inner bearing cone (42) is seated properly on the motor housing.
Note: Do not scratch Duo-Cone seal (41) or damage the Duo-Cone seal in the main
housing, or the motor housing during assembly of the two components. After installation of
the main housing on the motor housing, there will be a small gap between the components.
The gap between the components is caused by the Duo-Cone seal. The gap will be
eliminated during the installation of the coupling gear .
12. Fasten Tooling (F) and a suitable lifting device to sprocket housing (35). Carefully install
the sprocket housing on the motor housing.
13. Install the outer bearing cone on the sprocket housing. Make sure that the outer bearing cone
is properly seated.

16. Apply Tooling (J) on the threads of bolts (37) that hold coupling gear (38) in position.
Tighten bolts (37) evenly and tighten the bolts in diagonally opposite pairs to a torque of
570 ± 80 N·m (420 ± 60 lb ft).
7/17(W)w

17. Install O-ring seal (36) in sprocket housing (35).
18. Thoroughly clean the mating surface of sprocket housing (35) that contacts ring gear (34).

20. Attach Tooling (E) and a suitable lifting device to ring gear (34). Put ring gear (34) in
position on the sprocket housing. The weight of ring gear (34) is approximately 66 kg
(146 lb). Make sure that the alignment mark upon the sprocket housing and the ring gear
line with each other.

d. Drive spring pin (30) into planetary shaft (29).
The stake mark is at position (S).
e. Orient the split in spring pin (30) vertically to the carrier. Align the split in the spring
pin to the top or to the bottom. Make a stake mark on each side of the spring pin hole
in the carrier. Each stake mark should be approximately 2.25 ± 0.75 mm
(0.089 ± 0.030 inch) from the outside diameter of the spring pin hole.
