Note: Use a suitable press to install the cones on the drive shafts and the cups. If necessary, only preheat the cones
to 135 °C (275 °F) for no more than 1 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.

8. Use Tooling (A) and a suitable lifting device to install housing (26). The weight of housing (26) is
approximately 54 kg (120 lb). Install shims (23A). Use a suitable soft hammer to drive the wear sleeves into
housing (26) until the sleeves are flush with the top of the bore surface. Do not install the shims at this time.

9. Drill three equally spaced 8 mm (5/16 inch) holes in retainer (23) if necessary. The holes must be centered
on the existing bolt hole pattern and perpendicular to each surface.

10. Measure the thickness of retainer (23) at the three hole locations. Average the three measurements and
record the result as Dimension (A).

11. Install retainer (23). Install three of bolts (22). Tighten bolts (22) to a torque of 50 ± 7 N·m (37 ± 5 lb ft).
Completely loosen bolts (22). Finger tighten bolts (22). Use Tooling (D) to measure the gap between the top
surface of retainer (23) and the final drive housing at the three 8 mm (5/16 inch) hole locations. Record the
measurement from each of the three locations as the nominal gap or Dimension (B).

12. Calculate the shim pack thickness for the three measurement locations by subtracting Dimension (A) from
the Dimension (B) giving you Dimension (C). Remove bolts (22) and retainer (23).

13. Install various shims (23A) that is equal to Dimension (C) plus + 0.075 - 0.025 mm (+ 0.003 - 0.001 inch).
Install retainer (23). Install bolts (22). Tighten bolts (22) to a torque of 270 ± 40 N·m (199 ± 30 lb ft).

14. Preheat and install bearing cone (21) on drive shaft (20). Check for full seating of the cone with a Feeler
Gauge. With the drive shaft in a vertical position, set the housing on bearing cone (21).

15. Start bearing cone (33) (not shown) on the top of drive shaft (20). Do not preheat this bearing cone. The
bearing cone can be seated in position by using the sprocket during Step 17. Make sure that the bearing cone

17. Place the first sprocket (19) on drive shaft (20). The large diameter must face downward.

18. Place the second sprocket (19) on drive shaft (20). The hub must face downward and the large diameter must
face upward. Ensure that the lubrication holes (X) for the spline are aligned.

19. Install nut (17) to drive shaft (20) hand tight. Rotate the sprocket three full revolutions.

20. Tighten nut (17) while hitting the sprockets until the rolling torque is equal to the adjusting torque in Table
2. Rotate the sprocket three full revolutions and recheck rolling torque.

Note: If the rolling torque is outside the allowed range in Table 2, then repeat Step 20 until the rolling torque
value stabilizes within the acceptable range.

Table 2
Model Adjusting Torque

120H, 120K, 135H 7.91 ± 1.13 N·m (70 ± 10 lb in)

21. Loosen nut (17) by one LOCKING position. Hit the sprockets again and rotate the sprockets three full
revolutions.

22. Measure the rolling torque again. Refer to Table 3for the final rolling torque that is needed to rotate shaft
(20).

Note: Nut (17) may be adjusted further so that rolling torque falls in the acceptable range.
