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 ill 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.
32.
Put jaw (31) in position in the differential group
and install the two bolts (34) and the lockwire to
hold the jaw in position.
