Disassembly (Fig. 11)
1. Remove flange (19) from the pinion shaft (8) by re-
moving lock nut (18) and washer (17) from the threaded
end of the shaft. Use a bearing puller if necessary to re-
move the coupler flange (Fig. 12).
2. Secure carrier assembly (15) so that pinion gear
shaft (8) is facing up. Remove eight cap screws (16) se-
curing the front housing to the carrier assembly.
3. Separate front housing (2) from the carrier assembly
(15) using a cold chisel to initially separate the two parts.
Use a putty knife to further separate the housing and
carrier assembly (Fig. 13).
IMPORTANT: The bearing caps are marked for reas-
sembly. Place caps in a safe place to avoid damag-
ing their machined surface. Place caps back in the
same position during reassembly.
4. Remove four cap screws (11) and both bearing caps
from the bearing cradles (Fig. 14).
IMPORTANT: Keep mating bearing bearing cups
(30) with matching bearing cups (30) and bearing
caps.
5. Remove differential gears from the carrier assembly
by using two wooden handles under the differential case
(27) to pry up the case and gears (Fig. 15).
