CAUTION: HANDLE WITH CARE.
To ensure our customers receive all components with full integrity, we pack the motors separate from their Linkage
assemblies. This requires that the installer position and fasten the motor before continuing with the install. Please
follow the instructions below and handle the assembly carefully.
CAUTION: Dropping the assembly or any excessive impact MAY cause damage to the motor.
Instructions:
1. Position the gear cover in place as shown if not already in place.
2. Seat motor into position on the three mounting bosses. This may require an adjustment of the gear by moving the
swing arms.
3. After seating into place, fasten the motor with the three motor mount screws with 4mm Hex Head. Tighten screws
to 36 in-lbs (4N-m). Do not over torque.
INSTALLATION GUIDE
Attaching motor to Linkage assembly
The motors must be attached to the rear Linkages before installation. The Drivers side
