Removal and Disassembly
Side play and runout measurements taken during
disassembly will be very useful in reassembly.
(1) Drain the lubricant from the housing, and turn
the unit to have the cover facing up.
(2) Remove the cover and clean the differential
case and drive gear with kerosene, mineral spirits
or
other similar cleaning fluid.
(3) Measure for differential side play.
There should
be
no side play.
(4) To measure the drive gear runout on the differ-
ential case, (provided no side play was found) mount a
dial indicator Tool C-3339 on pilot stud Tool C-3288,
and load the indicator slightly when the plunger is at
right angles to the back face of the drive gear. (Fig.
42).
(5)
Measure the drive gear runout by reading the
dial indicator, while turning the drive gear several
complete rotations. Mark the drive gear and the case
at the point of maximum runout for use later in meas-
uring the differential case. The total indicator reading
should be no more than .005 inch.
If the runout is over .005 inch, the differential case
may have been sprung. A test of the case will be de-
scribed later.
