Removal Procedure
- Use a press with a minimum capacity of 10 tons.
- Support the torque rod (1) on a piece of 6 mm (0.25 in) wall steel tubing that is 127 mm (5 in) long with an inside diameter of 50.8 mm (2 in).
Caution: Do not use heat or a cutting torch to remove the bushings from the torque rod. The use of heat will adversely affect the strength of the torque rod.
- Remove the bushing from the torque rod by pushing directly on the bar pin of the bushing.
- Inspect the inside diameter of the ends of the torque rods.
- Remove any nicks and small scratches from the bore of the torque rod. Use an emery cloth.
Installation Procedure
Note: Do not use a petroleum or a soap base lubricant.
- Lubricate the inside diameter of the torque rod (1) and the new bushing using a vegetable base oil, such as cooking oil.
Caution: If the tightening torques recommended are not achieved and maintained, metal surfaces can work and wear the spring seats, axle bottom caps and possibly other components related in the total assembly.
- Support the torque rod on a piece of steel tubing during assembly. Center the bore of the torque rod in the tubing.
- Place the bushing in the bore of the torque rod in order to position the mounting flats of the bar pin 10 degrees counterclockwise to the shank of the rod.
- Press the bushing into the torque rod in order to extend the bushing 4.8 mm (0.1875 in) on the opposite side of the torque rod.
- Turn the torque rod over and press on the bar pin in order to center the bushing into the bore of the torque rod.
