12.Inspect the differential bevel gears by rotating the
axle ends.
13.Inspect the final drive gear teeth for excessive
wear or damage.
14.Check the differential assembly screw for proper
torque. The correct torque should be 12-14 ft. lbs.
(.75-.9 Nm).
15.Inspect the journal bearings inside the differential
housing for excessive wear by feeling the shafts for
an unreasonable amount of play.
16.If excessive wear or damage has been found, the
complete assembly must be replaced.
17.Remove the brake rotors and stators by sliding one
at a time off the ends of the splined motor shaft.
18.Inspect each side of both rotors for excessive wear
or damage.
19.Inspect the rotors internal splines for excessive
wear or damage.
20.Inspect the stators for excessive wear and
damage.
21.Replace rotors and stators as a complete kit if
excessive wear or damage is found, and inspect all
other mating parts.
22.Remove the oil filter. After inspecting the filter for
unusual particles that it may have trapped, dispose
of it properly and replace it with a new oil filter
during reassembly.
23.Using a 9/16" socket (or box end) wrench, remove
the three assembly bolts retaining the center
section in the upper housing.
24.Remove the center section assembly from the
housing. The pump block assembly should remain
in the upper housing on the input shaft, but may
stick to the center section. Inspect the check valve
plate bolt torque, but do not remove. Two styles of
check plates have been used one has three bolts
while the other has four. The one with four bolts
should be torqued from 170-240 in. lbs.
(10.5-14.7 Nm) while the one with three bolts
should be torqued from 135-185 in. lbs.
(8-11.5 Nm).
25.Remove the motor block assembly from the motor
shaft and inspect for unusual wear or damage. The
pistons should fit with very little side clearance in
the block bores, but must slide freely.
CAUTION:
The pump and motor piston
springs may push the center section
assembly out of position while you remove
these bolts.

CAUTION:
The aligning pins, motor shaft,
bypass plate, pump block and motor block
assemblies are NOT retained to the center
section or the upper housing and may
become separated from the assembly during
removal.
