Figure B–36. Disassemble Motor & Brake Assembly
12. Remove the reaction plate from the primary sun gear.
13. Remove the primary sun gear from the motor rotor
assembly.
14. Remove the small friction brake pad assembly from
its recessed pocket located in the axle housing.
15. Shown in previous drawing are the three major parts
used in the Eaton transaxle wet brake assembly, 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.
16. Remove the axle housing assembly gasket.
NOTE: Gasket may have remained on the axle housing.
17.Normally, any further disassembly of the brake
levers, push rods and etc. is not necessary, nor rec-
ommended. The brake lever shim, located between
the two brake levers, is used to adjust the brake lever
movement. This adjustment was made during the ini-
tial transaxle assembly.
Figure B–37. Disassemble Brake Housing
Brake Housing Disassembly (Eaton 750 only)
1. Using a 3/8” wrench, remove the four capscrews from
the brake cover.
NOTE: Make sure you DO NOT move the brake lever
unnecessarily, especially when it is out of the housing
assembly. The parking brake assembly incorporates
automatic self-adjusting brakes. Unnecessary activation
of the lever may cause the brake to expand and make
installation of the assembly very difficult or impossible.
