The use of Personal Protective Equipment (PPE) is required when using or handling hazardous
materials associated with operating and maintaining equipment (jet fuel, hydraulic luid, brake
luid, ethylene glycol, cleaning solvents, compressed air, and engine/axle oil). Failure to use
PPE when handling these materials could result in injury or death.
NOTE
On assembly of the brake packs, the oil low holes must be aligned with each other when being
itted to the brake pack carrier. If plates are to be reused position should have been noted in
disassembly and reinstall in same order as original.
1.
Ensure that the three alignment pins (Figure 1, Item 13) are placed in the grooves of the stub axle arm
(Figure 1, Item 5) securing them with grease. Ensure the pins are fully pushed into their location holes in
the housing.
NOTE
If plates are to be reused position should have been noted in disassembly and reinstall in same
order as original. New friction plates are to be soaked in Mobile 424 prior to assembly.
2.
Install the three friction plates (Figure 1, Item 11), four counter plates (Figure 1, Item 10), plate carrier
gear (Figure 1, Item 9) and snap rings (Figure 1, Item 8 and 12) on the spine axle rod (Figure 1, Item 7)
as one assembly.
3. Install the spline axle rod friction plate assembly (Figure 1, Item 7 through 12) into the stub axle arm
(Figure 1, Item 5). Align and push the assembly forward onto the alignment pins (Figure 1, Item 13) (2 not
shown) that are located in the drive stub axle arm (Figure 1, Item 5).
4. Ensure the spline axle rod is engaged within the stub axle arm s (Figure 1, Item 5) spline gear.
5. Ensure the oiling holes on the friction plates and counter plates match up.
6. Apply loctite 574 on the stub axle arm (Figure 1, Item 5) mating surface.
7. Carefully hoist the stub axle arm assembly (Figure 1, Item 5) onto the differential housing (Figure 1, Item 1).
If necessary using a soft-faced mallet, taping the case.
8. Apply loctite 242 to 14 mount bolt threads (Figure 1, Item 6) (one shown).
9. Snug all mount bolts (Figure 1, Item 6) then torque in a crisscross pattern to 178 ft-lbs.
