When installing new tie rod components during truck assembly, or when adjusting the tie rods to obtain the correct steering geometry, be sure to locate the clamp assembly before the bolt and nut are tightened. Failure to locate the clamp correctly on the tie rod could shorten the service life of the tie rod assembly.

Use the following steps to correctly locate the clamp assembly on the tie rods.

Illustration 1. Dimension for location the clamp assembly on either end of the tie rod. (A) 6.3 mm (.25 in).

1. Position the clamp assembly a maximum of 6.3 mm (.25 in) from the ends of the tie rod. See Illustration 1.

2. Align the open portion of the clamp assembly with one of the slots in the end of the tie rod as shown in Illustration 2.

Illustration 2. Open portion of the clamp assembly (1) aligned with one of the slots in the tie rod (2).

3. Tighten the 5/8in clamp assembly bolts on the 768C, 772B Tractors, 769C, 773B Trucks and 771C, 775B Quarry Trucks to 215 ± 40 N·m (160 ± 30 lb ft). Tighten the 3/4in clamp assembly bolts on the 776B, 776C Tractors and 777B and 777C Trucks to 370 ± 50 N·m (275 ± 35 lb ft).
