HOSE AS 3982127 - Caterpillar

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).
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).

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

Place the first sprocket (19) on drive shaft (20). The large diameter must face downward.
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.
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.
Loosen nut (17) by one locking position. Hit the hub of sprockets (19) again.
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.
