Clean
WARNING
Cleaning solvents can be flammable and toxic and
can cause skin irritation. When using cleaning
solvents, always follow the solvent manufac-
turer’s recommended safety procedures.
WARNING
Compressed air is used for cleaning or drying
purposes, or for clearing restrictions. Wear pro-
tective clothing (goggles/shield, gloves, etc.) to
avoid injury to personnel.
1.
Clean bearings by placing them in a wire bas-
ket and immersing in a container of fresh sol-
vent. Agitate the bearings in the solvent to re-
move all traces of old lubricant.
2.
After cleaning the bearings, dry them with
clean compressed air. Take care to prevent
spinning the bearings when using a compressed
air jet.
3.
Immediately wrap bearings in a lint-free cloth
to protect them from dust and other foreign
matter.
Inspect
1.
Inspect for loose, missing, cracked, burned or
damaged hardware.
2.
Inspect all parts for dents, holes, bends, burrs,
rust, corrosion, or marred finish.
Assemble
1.
Install new seals on the spindle. Lubricate the
seals with grease. If necessary, press new bear-
ing cones on the spindle.
2.
Lubricate the bearings with wheel bearing
grease. Verify the bearings are filled with
grease. If necessary, press the new bearing
cups into the steering axle frame and bearing
cap. Install the wear sleeve in the steering axle
frame.
3.
Install the spindle in the steering axle. Install
the bearing cap without the O-rings. See Fig-
ure 8.
Measure the clearance between the bearing cap
and the axle. Remove the bearing cap and install
enough shims to provide a preload of 0.00 to
0.13 mm (0.000 to 0.005 in.).
NOTE:
The spindle bearings must have no clear-
ance. Install shims 0.00 to 0.13 mm (0.000 to
0.005 in.) less than the measured gap.
4.
Install the O-ring on the bearing cap. Apply
Loctite ® 242 to threads of capscrews. Install
the bearing cap and capscrews. Tighten cap-
screws to 47 N•m (35 lbf ft).
5.
If necessary, repeat the steps above for the
other spindle and tie rod.
