Control Arm and Damper Removal and Installation
Before beginning tear down clean work area thoroughly
and cover workbench with clean paper. This is extremely
impor-tant as just one grain of sand can cause damage to
the Hy-drostatic Rotating Group in the Transaxle.

A - Control Arm
B - Washer
C - Main Cap Screw
D - Spring Locking Pin
E - Washer
