Installation

1. Remove original steering box and mounting brackets.
2. Install 7/16” studs into the steering box per drawing. Note: the 7/16” x 2” long stud will be installed in the upper rear mounting hole. Use of Loctite is recommended.
3. Locate the (3) .700” thick sleeves. Place these sleeves over the 7/16” studs that are 2 1/2” long. One sleeve (.275” thick) will be placed over the 7/16” stud that is 2” long. As the steering box is placed on the JTO steering box mount, the 7/16” stud that is 2” long will need to be started first! Next, torque all (4) 7/16” lock-nuts to 65 ft-lb.
4. Place the steering box and JTO steering box mount onto the original mounting holes in the chassis; torque the 5 nuts to 55 ft-lb each. Next, place the 5/8” x 2 1/2” bolt through the side of the frame and into the hole that corresponds with the nut that is welded into the JTO steering box mount.
5. Finally, replace the steering shaft, pitman arm, and the power steering lines.
