Reassembly
l.Check all parts for wear or
damage and replace as neces-
sary.
a)Differential housing:
Check guide grooves for outer
plates and pressure rings for
wear.
b)Pressure rings:
Check for signs of heavy wear or
ridging on the guide dogs and con-
tact surfaces. The rings must move
easily in the differential housing.
c)Axle bevel gears:
The contact surfaces for the take-
up plates should not be worn and
the inner plates must move easily
on the splines.
d)Plates:
Check inner and outer plates for
wear. There should be no signs
of excessive wear on the guide
dogs of the outer plates or the
teeth of the inner plates.
2.Apply transmission oil to all slide
faces of plates, pressure rings
and differential axles prior to re-
assembly.
3.Insert take-up disks so that the dog
engages the hole in the housing or
cover. As an aid to assembly,
apply enough grease to the disks to
hold them in place.
