Safe means of lifting and supporting the vehicle: jack and jack stands, wheel ramps, or lift.
Socket wrench or breaker bar
15mm deep socket
15mm open end wrench(ratcheting if available)
18mm open end wrench
T30 torx socket or driver
Components supplied should include:
1x Damond Motorsports Rear Motor Mount, pre-assembled with bushings and sleeves
1x 16mm head bolt
1x 18mm head lock nut
1x 8mm Allen head bolt (not used on the RS)
(CAUTION: allow the vehicle to cool down fully before attempting any work)
Begin by properly supporting the vehicle in the air using stands, ramps, or a lift.
Remove the 2 plastic undertray clips (circled green)
Remove the 8 x T30 screws securing the undertray (circled yellow) and remove the undertray.
Locate the factory rear motor mount assembly attaching the transmission casing to the subframe.
Loosen and remove the 18mm bolt connecting the RMM to the transmission bracket, then remove the 15mm bolt securing the mount to the subframe.
With the RMM bolts removed slide the RMM into the subframe to allow for better access to the transmission bracket bolts. First gently pry off the PTO line hold down covering the rear most trans-bracket bolt.
Remove the 3 x 15mm transmission bracket bolts and remove the transmission bracket from the vehicle(the backside bolt not shown is what the yellow arrow is pointing towards)
Remove the factory RMM and insert the Damond Motorsports RMM into the subframe with the full flanged bushing facing the right side of the car.
Re-install the transmission bracket using the 15mm bolts previously removed with the bracket(yellow). Tighten to 45-50lbs/ft(65Nm).
Slide and position the Damond Motorsports RMM into place(Note: this may take some light force and wiggling to position the mount in place and line up all the mounting points). Insert the provided 16mm bolt through the mount and the transmission bracket, and thread on the provided nut on the other side. Insert and thread in the previously removed 15mm subframe bolt. Tighten the subframe bolt first(blue) to 75-80lbs/ft(100Nm) then tighten the 16mm bolt(green) to 50lbs/ft(65Nm) while securing the 18mm nut with an open end wrench.
Reposition the PTO line holder in place and place it on the back nut/stud
Re-install the engine undertray.
Lower the vehicle, and go for a quick test drive to ensure there's no knocking from bolts not being fully tightened. Note: there will be added NVH immediately upon installing the mount. Generally after 500-1500 miles some of the NVH will subside to a bit lower than immediately after installing the mount. At 100 miles we strongly recommend checking the torque of all the fasteners accessible without fully removing the mount.
Congratulations! You've successfully installed the Damond Motorsports Rear Motor Mount. Enjoy all the benefits the mount has to offer on your Focus ST.
