the friction pad assembly, reaction plate and backup
plate. When the brake is applied, the rotating reaction
plate is squeezed between the stationary friction pad
and the backup plate.
17.Remove the axle housing assembly gasket.
NOTE: This gasket may have remained on the axle
housing.
Normally any further disassembly of the brake levers,
push rods and etc. is not necessary nor recommended.
The brake lever shims located between the two brake
levers are used to adjust the brake lever movement.
This adjustment was made during the initial transaxle
assembly.
NOTE: Standard single handle brake arrangement
shown.
9.4 MOTOR ROTOR DISASSEMBLY
IMPORTANT: Be extremely careful when removing the
motor rotor assembly. The ball pistons are spring
loaded in the bores and must remain intact because
each ball piston is matched to its respective bore.
1. The best way to remove the motor rotor assembly
is to place a separate motor race on top of the
existing motor race in the housing assembly.
2. Hold the separate race securely in position.
3. Then carefully pull the motor rotor assembly
outward until the ball pistons are fully engaged in
the grove located in the center of the separate
race.
4. Carefully remove the rotor assembly and race
together as a set, handling the motor rotor
assembly only.
NOTE: If a separate motor race is not available, work a
wide rubber band around the outside of the motor rotor
to hold the ball pistons in their bores.
It is essential that the ball pistons be retained in their
bores during handling. This is especially true for the
motor rotor(s), as the motor ball pistons are spring
loaded in the bores.
NOTE: The remaining transaxle axle housing assem-
bly, if applicable, can be serviced at this time.
5. Reposition the housing assembly, Using a 3/8 inch
socket or end wrench, remove the self tap screws
from the cover assembly.
NOTE: One self tap screw is located in the case drain
port.
6. With all self tap screws removed (13), carefully
separate and remove the cover from the housing
assembly.
7. Turn the cover assembly over and remove the two
buttons.
8. These two buttons may have dropped out into the
housing assembly during removal of the cover.
