DIFFERENTIAL AND CARRIER ASSEMBLY (LOCK TYPE)
d)
If bevel pinion shaft is too near to center
of bevel gear, short heel contact will result
as shown. The teeth of pinion will be in
contact with toe ends of concave faces
(part that makes a curve toward the
inside) and the heel ends of convex faces
(part that makes a curve toward the
outside). To correct this, move pinion
shaft away from gear by an increase of
the shim thickness between pinion cage
and carrier. After this is done, check gear
clearance (backlash) and tooth contact
again.
NOTE:
Several adjustments of both pinion
and bevel gear can be needed before
correct tooth contact setting and
gear clearance (backlash) is made.
Always remember that a change to
gear clearance (backlash) will also
change the tooth contact setting. Be
sure gear clearance (backlash) is in
correct
adjustment
before
tooth
contact is checked.
e)
After correct gear clearance (backlash)
and tooth contact setting is made, remove
extra prussian blue, red lead or paint from
bevel gear and pinion.
30.
Remove the guide bolts and install the
remainder of bolts (32) to hold the pinion shaft
housing to the carrier assembly.
31.
Install the locks and bolts for the adjustment
nuts. Install the lockwire to hold bolts (33) and
the bolts for the adjustment nuts.
33.
Put jaw (31) in position in the differential group
and install the two bolts (34) and the lockwire to
hold the jaw in position.
