Preliminary Procedure Assemble the variable low clutch. Refer to Variable Low Clutch Plate Installation . Service the variable low clutch with the variable high clutch installed onto the drive motor rotor. This will prevent contact of the drive motor stator copper end coils with the work surface. CAUTION: DO NOT contact or rest the drive motor stator on the copper end coils. Damage to the copper end coils may cause a high voltage short during vehicle operation, resulting in component damage.
