NOTICE: Depending on the bolt pattern used to install
the Ultrex Mount to the Outer Plate of the Quick Release
Bracket, the Right Sideplate may need to be removed to
access the mounting holes in the base of the Mount. Use a
#2 Screwdriver to remove the Right Sideplate if necessary.
a. Align the Base Extrusion with the mounting holes of
the Outer Plate. Place the Hold Down Strap between
the Base Extrusion and the Outer Plate. The strap
must be located in the Relief Cut on the Outer Plate,
or Quick Release Bracket failure may occur.
b. Use six 1/4” x 1 1/8” Socket Head Screws, six Flat
Washers, and six Nylock Nuts retained from the
disassembly to fasten the motor mount to the Outer
Plate. The Screws should pass through the Base
Extrusion, the Outer Plate, then the Flat Washers
and be secured by a Nylock Nut. Secure with a
Socket Wrench and a 7/16” Box End Wrench.
c. If the Right Sideplate was removed, reinstall it with a
#2 Screwdriver.
a. Take the Slide Plate and align the mounting holes
on the plate with the mounting holes on the Base
Extrusion. The mounting holes closest to the short
edge of the plate should face outboard. Make sure
the Hold Down Strap is placed between the Mount
and Slide Plate.
b. Using a #3 Screwdriver, fasten the Base Extrusion to the
Slide Plate with six 1/4” x 7/8” Pan Head Screws and six
Nylock Nuts retained from the previous installation.
The Screws should pass through the Base Extrusion
and Slide Plate, then secured with a Nylock Nut.
