Prepare Parts for Assembly

19

4.

Check the mounting surface for the side gear
shafts in the case halves. Check that the bores
are free of burrs at both ends.

5.

Inspect the diameters of the side gear shafts.
If any should show signs of wear, grooves,
depressions, etc., replace them all.

6.

Check the speed selector and teeth
synchronization at low speed (lock plate and
sun gear). Replace the parts that show signs of
excessive wear or are marked or grooved.

Axle Shafts

Check for notches and excessive wear of the
splines and for out-of-roundness of the flange
bores.

Case

Check for cracks on any surface or burrs on the
machined parts.

Yoke

Replace the yoke if it shows excessive wear in the
retainer area.

Carrier

Check for signs of cracks, loose studs, burrs or
grooves on the machined surfaces.

Storage

After the parts have been cleaned, dried and
inspected, they must be assembled immediately
or covered with a film of oil as specified in
Section 6 for the purpose of preventing oxidation.

The parts that are to be stored or packed must be
covered with a coating of oil or any antioxidant
and kept in closed boxes or wrapped for
protection from dust, moisture or rust (except
for components already protected by paint, etc.).
