bottom of the mount.
2.1.2B: Using the provided hardware attach the drop length to the drop length adapter, and then
attach the motor to the drop length. It is recommended that only two of the four bolts are installed
until wiring is complete, one for the mount to drop length side and one for the motor to drop
length side. Do not torque them until the wiring and safety cable are installed. It may be
necessary to partially remove the bolts in order to get the wiring past. Once the wiring and safety
cable are installed, torque the bolts to 30 ft-lbs.
