Front Differential Assembly
1. Be sure that all parts are clean and free of any dirt or
debris. Make sure that all residual oil has been removed
from differential components.
2. Check the condition of the square sectioned O−ring
located on the cover plate. Make sure that it is clean and
free of any cuts or nicks.
IMPORTANT: When installing male output hub as-
sembly into cover plate, be careful to not damage
the seal in the cover plate. The seal cannot be ser-
viced separately.
NOTE: The male output hub has an extended bushing.
3. Press the new male output hub/bearing assembly
into the cover plate assembly. The bearing has a slight
interference fit to the bore, so it should not take much
force to press in. Take care to not damage the seal in the
cover plate during installation of the output hub assem-
bly.
4. Set the armature plate onto the coil located in the
cover plate. The internal tangs of the armature plate
should face up as shown.
5. Place the gear spacer on top of the armature plate
and secure with retaining ring. Make sure that retaining
ring is fully seated into groove in cover plate.
