Disassembly
The two gear cases, right and left can be removed from
the housing without requiring the entire axle to be dis­
assembled.

each end. Disconnect hydraulic cylinder rod end from
drag link arm.
2. Remove bolts (Fig. 23, Item 23 and 21) securing gear
case to axle housing and pull gear case complete with

on the bottom right side (viewed from center of axle) is
a reamer bolt (Item 21).

lightly on the exposed shaft end so that the final drive
case will slide off the gear case.
