Special Instructions
The addition of the Spring and Thrust Button between the input and output shafts necessitates the fabrication of a “U” bracket to
assist in measuring the shaft end play. Proceed as follows:
Procedure - Measure and Adjust Input Shaft End Play
1. Fabricate a “U” bracket from 1“ flat stock (minimum thickness 0.125”) as specified in the illustration.
2. If axle is disassembled, build up a 0.045” (0.024 mm) thick shim pack and place shim pack and bearing cover on power di-
vider cover. Then proceed with Step 3.
If axle is assembled, remove input shaft nut, flat washer and yoke. (NOTE: Axles built with metric threaded nuts do NOT use
flat washers) Then proceed with Step 3.
Note: Bushing removed from current production output shafts, See notes on page 35.
