b. Cleaning and Inspection.

(1) Wipe the tie rod ends with a cloth

dampened with a cleaning solvent. Clean all remaining

parts with solvent and air dry.

(2) Inspect the tie rod ends for damaged

threads, binding or seizing of the studs, scoring or

corrosion. If tie rods are bent or damaged, they are to

be replaced.

c. Reassembly, Installation and Adjustment.

(1) Reassemble the locknuts and tie rod ends

on the tie rods. Do not tighten the locknuts until the tie

rod length is adjusted.

(2) To adjust the tie rods, raise the truck with

a jack under the counter-weight to raise the steering

wheels from the floor. Disconnect the power steering

cylinder from the pivot arm assembly, as directed in

paragraph 4-59.

(3) Place the wheels in a straight ahead

position, so that they will track with the drive wheels.

Install the tie rods between the steering knuckles and

the pivot arm assembly. If one wheel remains in a

straight position and the other is turned slightly in or

outward, adjust the tie rod of the wheel that is not

straight, as zero degrees toe-in must be maintained at

all times.

(4) To adjust the tie rod (fig. 4-56) loosen the

adjustment plug and remove the rod from the pivot arm

assembly. Swing the tie rod away from the steer axle.

Align the steer wheel so that they are parallel with the

side of the truck. Turn the tie rod on to the ball socket to

shorten the tie rod, or turn the rod off of the ball socket

to lengthen the tie rod.

(5) After the correct adjustment has been

achieved, tighten the locknuts and replace the tie rod on

the pivot arm assembly. Tighten the adjustment plug

(refer to fig. 4-56 and 4-54).

(6) Adjust and install the steering cylinder as

directed in paragraph 4-59.
