(5) Check the axle shaft collars for wear, damage, out of round, and corrosion. Check the pin holes for wear
and cracking or splitting edges. Replace worn and defective axle shaft collars.
(6) Inspect the pins for wear, scoring, and worn grooves in the pin body. Replace the pins if they are twisted,
cracked, or grooved.
(7) Check the adjusting bolts for damaged, corroded, twisted, or stripped threads Replace all defective
adjusting bolts.
(8) Inspect the axle shaft for wear, twisting, cracks, and breaks; check the bearing journals for wear, scoring,
cuts, and flaws. Replace the axle shaft if it is bent or twisted, or if the bearing journals are worn or scored.
e. Reassembly.
(1) Press the inner dust guards (8) and bearings (9) on the axle shaft (6). Pack the bearings with grease.
(2) Press the outer and inner bearing cups (10) into the steering rolls.
(3) Install the steering rolls on the axle shaft (6) and press the outer bearings (9) and dust guards (8) on the
outer ends of the axle shaft (6).
(4) Press the axle shaft collars (4) on both ends of the axle shaft (6), making sure that the pin holes in the axle
shaft and axle shaft collars are properly alined.
(5) Secure the axle shaft collars (4) with the collar pins (7).
(6) Install the bearing adjusting plates (3) on both ends of the axle shaft (6).
(7) Install the bearing adjusting bolts (2) but do not tighten them.
g. Adjustment. The steering roll axle shaft bearings are adjusted by means of the bearing adjusting plates (3) and
bolts (2). Turn the adjusting bolts clockwise to tighten the bearings and counterclockwise to loosen them. The two
adjusting bolts on each side of the axle shaft (6) adjust the bearings in the entire steering roll assembly. Adjust the
bearings so that there is no excessive side play in the bearings. Make sure that the bearings are not too tight or binding.
