Installation

  1. Use alcohol wipes to clean the mating surfaces between the RH drive unit mount and drive unit.
  2. Place a shear plate on the outboard side of the drive unit mount so that the shear plate bolt holes align with the motor mount bolt holes. Caution: Ensure that the bottom holes on the shear plate are not slotted. If the bottom holes are slotted, replace the shear plate with one that is not slotted. Note: Install a shear plate even if the original drive unit mount did not have a shear plate.
  3. Insert new bolts (x2) through the lower holes in the shear plate and motor mount.
