17. Remove the brake rotors and stators by sliding one at
a time off the end of the splined motor shaft.

damage.
19. Inspect the rotor's internal splines for excessive wear
or damage.
20. Replace rotors and stators as a complete kit if exces-
sive wear or damage is found. Inspect all other mating
parts.
21. 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.
22. Using a 9/16" socket, remove the three assembly
bolts retaining the center section in the upper housing.
The bolts are Lock-tite-ed in and may require the use
of a breaker bar to loosen.
CAUTION: The pump and motor piston springs may
push the center section assembly out of position
while you remove these bolts.
23. 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.
23a Check 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 plate with four bolts should be torqued to 170 to
240 in-lbs., while the plate with three bolts should be
torqued to 135 to 185 in-lbs..
NOTE: The model 0800 has no check valve plate.
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.
