(1) DRIVE PINION BEARING
CUP REPLACEMENT.
Place
the drive pinion sleeve in a vise and, using a puller that hooks behind
the bearing cup, pull the bearing cup (fig. 40). Repeat this operation
to remove
the other cup.
To install new
bearing
cups,
place the
Pinion sleeve in a vise. Place
the cups in position on the pinion
sleeve and, using a replacer that contacts the bearing cups evenly,
draw the cups in the sleeve until they are seated flush with the
shoulder in the sleeve.
(2) DRIVE
PINION
BEARING
REPLACEMENT.
Remove
the bearing from the pinion, using a puller that applies pressure to
the inner race. Install a new bearing, using a puller that applies pres-
sure to the inner race of the bearing.
(3) DRIVE
PINION
PILOT
BEARING
INNER
RACE
RE-
PLACEMENT.
Remove
the lock ring, using a sharp punch. Place
the drive pinion so that the race rests on a solid base and, with a
two-pound
hammer,
strike repeated
blows along the race surface.
This will cause
the race to expand
slightly.
Drive
a sharp chisel
between the rear edge of the race and the pinion shoulder to start
the race. Drive the race off the pinion, using a heavy punch. To install
a new race, place it on the pinion with the chamfered side facing the
Pinion. Press the race on the pinion until it is against the shoulder of
the pinion. Install the lock ring.
