21. NOTE: It is imperative that all power train parts be clean and free of rust before and during
assembly. Parts suspected of poor quality should be verified for conformance before using.
NOTE: Do not use preheating of bearing cones or precooling of bearing cups when you assemble
the final drive unit in a shop. Use a suitable power press to install the cones on shafts and cups in the
housing bores.
NOTE: Preheating or precooling of bearing cones or cups may be used to aid assembly where a
power press is not available. Limit the heating of the cones to 135° C (275° F) for no more than one
hour. It is important to reseat the cone or the cup with a suitable driver after the bearing and adjacent
parts have reached a uniform temperature.
Tandem Housing Assembly
1. Lower the temperature of bearing cup (32) and install it in housing (29). Check for full seating of
the cup with a 0.0005 mm (.0002 in) Feeler Gage.

22. 2. Place housing (29) in vertical position with the flange down. Install lip seal (31) in housing (29).
The lip of the seal must face outward. Lubricate the sealing lip with the lubricant being sealed.
3. Lower the temperature of bearing cup (30) and install it in housing (29). Check for full seating of
the cup with a 0.0005 mm (.0002 in) Feeler Gage.
4. Coat the surfaces of thrust washer (28) with 6V-4876 Lubricant and install it on housing (29).

24. 5. Coat the inner and outer surfaces of two wear rings (27) with 6V-4876 Lubricant and install
them on housing (29). The diagonal cuts in the wear rings must be located 90 degrees apart. Refer to
the illustration D34768 for an example of the locating positions.
6. Install lip seal (26) in tandem housing assembly (25). The seal must be installed flush with the end
of the tandem housing assembly (25). The sealing lip must face outward.

25. 7. Install Tooling (A) and a hoist to tandem housing assembly (25). Carefully install tandem housing
assembly (25) on the final drive assembly. Make sure wear rings (27) remain in the 90 degree
location to each other.
8. Coat surfaces of thrust washer (24) with 6V-4876 Lubricant and install it in tandem housing
assembly (25).
NOTE: For rebuild of the oscillation joint, start with the same shim pack that was removed from the
original assembly.
9. Install the shim pack and retainer (23) with the bolt holes aligned. Install 16 bolts and washers
(22). Tighten the bolts to a torque of 270 ± 15 N·m (200 ± 11 lb ft). Use a dial indicator to check if
the housing end play is within 0.0 to 0.060 mm (0.0 to .0025 in). Adjust the shim pack thickness
and repeat the procedure if the end play is not within specification.
10. Preheat and install bearing cone (21) on shaft (20). Check for full seating of the cone with a
0.0005 mm (.0002 in) Feeler Gage. With the shaft in a vertical position, set the tandem housing
assembly down on bearing cone (21).
11. Start the second bearing cone on the top of shaft (20). Do not preheat this bearing cone. It can be
seated in position by using the sprocket during step 12. Make sure that the bearing cone is seated in
the cup.
12. Place the first sprocket on shaft (20). The large diameter must face downward.
13. Place the second sprocket on shaft (20). The hub must face downward and the large diameter
must face upward. Make sure that spline lubrication holes (X) are in alignment.

26. 14. Install the spanner nut and adjust the bearing preload.
a. Install spanner nut (17) to the drive shaft.
b. Rap the sprockets with a hammer while you rotate the shaft. Continue to turn the shaft. Tighten
nut (17) in order to achieve a rolling torque of 7.9 ± 1.1 N·m (70 ± 10 lb in).
c. Back nut (17) by one lockring position. Rap the sprockets in order to ensure that the bearings are
seated properly.
d. Check the final rolling torque. The final rolling torque should be 2.3 ± 1.1 N·m (20 ± 10 lb in). As
required, adjust nut (17) in order to achieve the correct final rolling torque.
NOTE: The rolling torque in the Test & Adjust, "Final Drive Preload-Check" includes more
components. The rolling torque is substantially higher. Do not confuse the two values for rolling
torque.
15. Install bolt and washer (18) and lock (16) that hold spanner nut (17) to the drive shaft. Tighten
bolt (18) to a torque of 50 ± 10 N·m (37 ± 7 lb ft).
16. Place tandem housing assembly (25) in a vertical position, Place the sprockets on wooden
blocks. Position ring gear (15) to tandem housing assembly (25).
17. Install eight bolts and washers (13) and four plates (14) in order to hold ring gear (15) to tandem
housing assembly (25). Tighten bolts (13) to a torque of 50 ± 10 N·m (37 ± 7 lb in).
18. Install washer (12) and retainer (11) in planet carrier assembly (3).
