It will be good practice, for ease on reassembly,
to mark the position of differential carrier caps
and bearing adjusters relative to supports
in
order
to assure correct pairing of parts.

Inspection and Repair.
Prior to examining all components visually. clean
them thoroughly.
The case must not be cracked and bearing bores
must show no sign of wear or damage
I
otherwise
bearing cups may be turning in their seats.
Ball bearings should be in top condition and
show no axial play in excess of .02" (0.5 rnm).
maximum limit; radial play of bearings must not
be greater than
.002" (0.05
mm).
Check that the inner race revolves smoothly on
the outer race: hold the bearing firmly with hands
and rock it back and forth; no roughness must
be felt.
Replace bearings
if
there is even a shadow of
doubt about their efficiency.

Place the mainshaft and countershaft on centers
and using a dial indicator check them for
misalign-
ment in excess of .0008" (0.02 rom) to bearing
bores; also check the shaft splines for absence of
indentation marks.
The reverse shaft should show a very smooth
surface with no sign of pitting; clearance between
shaft and sliding gear bushing must be greater
than
.006" (0.15
rom).
All gears should not show excessive tooth wear
and teeth of constant mesh gears should mate on
their whole working length and depth; tooth face
must be smooth and show no indication of seizure.
