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 roll-
ers in cage), and install a dial indicator to mea-
sure 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.
NOTE: 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 en-
sure 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.
IMPORTANT: Usecautiontopreventthetipsofthe
slingers from contacting the sealing surface on the
end of the shaft, or seal failure we occur.
