8 To make sure that the nuts of the wheel tie bolts are serviceable, install them onto
the bolts. If you can turn the nut with your hand more than to the self-locking
section, replace the nut.
9 Examine the brake disc. Unusual wear, scoring, corrosion, cracks, deformation or
other damage are causes to reject the part. If the disc thickness is worn more than
0.025” of the new disc, replace the disc. Remove small corrosion and defects in the
surface finish with a 220 grit sandpaper. Remove corrosion from the non-braking
part of the disc. Then paint the non-braking part and/or apply corrosion preventive
compound to prevent corrosion.
To assemble the wheel:
Assemble the wheel carefully. Do not cause damage to the protective finish of the
wheel.
1 Assemble the wheel on a clean, flat surface.
2 Install the bearing races again, if applicable.
a) Clean the race bore of the wheel bearing. Apply a thin coat of wheel bearing
grease to the race bore.
Make sure that the bearing race is correctly aligned and not tilted to one side to
prevent damage.
b) Put the bearing race in the wheel bore.
Make sure that you hold the wheel half at the bottom of the bearing seat. Do not
apply too much force. If you do not obey this precaution, the wheel casting can
break.
c) Put the wheel half in the press as shown in Figure 32-10.
