MOTOR/ELECTRONIC BRAKE ASSY.

1. A 6.00mm hex wrench is the basic
tool required for undoing the four
Motor Studs.

2. Some of the studs may require
extra force. That may require a
cranked hex key or tool.

3. Limited room may also require the
use of a hex key driver tool. If the
Drive Train has to be removed, do
that first and then take the Motor off.

4. It is a good idea to mark the top of
the Motor and Transaxle for refitting
purposes.

5. Carefully withdraw the Motor from
the Transaxle.

6. The Motor/Electronic Brake Assy.
