ing to the B position matching mark on the final drive companion
flange.
CAUTION:

For matching mark, use paint. Never damage drive pin-
ion.

The matching mark B on the final drive companion flange
indicates the maximum vertical runout position.

Revision: 2004 November 2004 FX35/FX45
INSTALLATION
1. Apply multi-purpose grease to sealing lips of the oil seal. Drive
the oil seal into the differential case using special service tool so
that the oil seal flush with the gear carrier end.
NOTE:

When installing the front oil seal, be careful not to get it
inclined.

Discard the old front oil seal. Always replace it with a new
one.
2. Install the companion flange while align the matching mark of
the drive pinion with the matching mark B of the companion
flange.
3. Apply oil to the drive pinion threads and the seating surface of
drive pinion lock nut.
4. Using the drive pinion flange wrench. Install drive pinion lock nut
with tool.
CAUTION:
Do not reuse the drive pinion lock nut. Always replace it
with a new one.
5. Install the front propeller shaft. Refer to PR-5, "
