Note: Verify that all components of the power train are clean and free of foreign material prior to assembly.

Note: Check all of the components and all of the O-ring seals for wear or for damage. Replace the components, if necessary. Lubricate the O-ring seals lightly with the lubricant that is being sealed

Note: Use a suitable press in order 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 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.

2. Place housing (29) in a vertical position with the flange downward.

3. Install lip seal (31) in housing (29). The lip of the seal must face outward. Lubricate the lip seal (31) with the lubricant which is being sealed.

4. Lower the temperature of bearing cup (30) and install bearing cup (30) in housing (29). Check for full seating of the bearing cup with a Feeler Gauge.

8. Use Tooling (A) and a suitable lifting device in order to install housing (26). The weight of housing (26) is approximately 54 kg (120 lb). Install shims (23A). Use a suitable soft hammer in order 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.

Illustration 8 g02783255

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) in order 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).

10

13. Install a number of 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 is seated in the cup.

16. Install drive shaft (20) in housing assembly (2).

19. Install nut (17) to the drive shaft (20). Rotate drive shaft (20) and hit the hub of sprockets (19) while nut (17) is being tightened to a torque of 11 ± 1 N·m (100 ± 10 lb in) above seal drag.

20. Loosen nut (17) by one locking position. Hit the hub of sprockets (19) again.

21. The final torque that is needed to rotate shaft (20) should be 2 ± 1 N·m (20 ± 10 lb in) or 3.95 ± 1.13 N·m (35 ± 10 lb in)above the seal drag depending on machine model.
