4. Check the end play of the pinion shaft with the
pinion side facing down, to ensure an accurate
measurement. Rotate the shaft two complete
revolutions to seat all components (bearing
rollers in cage), and install a dial indicator to
measure shaft end play. Allowable end play is
0.002 to 0.008 inches. If necessary, use a
screwdriver to pry upwards on the pinion gear to
obtain an end play reading. Remove the snap ring
and add the required thickness of shims between
the spacer washers to achieve the correct end
play.
NOTICE: The shims must be sandwiched between
two hardened washers to protect them from the
bearing and the snap ring groove.
Recheck the endplay as described above to
ensure the assembled endplay is correct.
5. Install an oil slinger, 1, into the groove on each
end of the pinion shaft. Be careful not to scratch
the sealing surface on the shaft as this will cause
the shaft seal to leak, causing module failure. The
slingers are bidirectional in nature, and may be
installed in either direction on the shaft.
NOTICE: Usecautiontopreventthetipsofthe
slingers from contacting the sealing surface on the
end of the shaft, or seal failure we occur.
