Remove retaining ring “R”, pin “S” and the (2) “T” bushings from the brake linkage. Pull the end of brake
band “U” away from brake drum “V”.
Note:
As you complete the next step, look for the “W” shims between some of the “X” pillow blocks and the
“Y” frame members. These shims compensate for slight variations in the height of the frame mem-
bers. Be sure to install the shims on the same frame member when reinstalling the differential. If the
shims are not installed in the proper location, the wheels will be difficult to turn when the “P” bolts are
tightened.

Remove the remaining “P” bolts and remove the differential assembly from the machine.
If Replacing the Differential...

Clean all dirt from the axle shafts, using emery cloth, a file or a wire brush and loosen the “Z” set screws
(see Figure 5).

Collar “AA” must be turned to release the pillow block bearing from the axle. Use a drift punch and
hammer to break the collar loose, as shown in Figure 6. If the collar does not release, try moving it in the
opposite direction.
8
Slide the pillow blocks off of the differential axle.
9
See Figure 4. Remove the (4) bolts holding brake drum “V” and sprocket “BB” in place and slide them off
of the differential.
Note:
Repair parts for the differential itself are not available from Advance. Replace the entire differential if
the axles or gears are damaged.
