Motor Head Unit Installation Motor Head Unit Installation
The above figure shows how the u-bolt fits over the tube, and restrains the motor
unit to the tube, without reliance on a platform or interfering with the side plates.
The motor can be mounted, on these kinds of doors, in any position. Generally the
position is chosen to best permit the routing of the power cable and the release
lanyard.
On the next page, the sequence to assemble the u-bolt is shown.
