8.11.4 NOSE WHEEL INSPECTION AND REPAIR
1.
Clean metal parts in solvent and dry thoroughly.
2.
Inspect wheel halves for cracks. Cracked wheel halves should be discarded and new parts
used. Sand out nicks, gouges and corroded areas. Clean thoroughly
3.
Carefully inspect bearings for damage and discolouration.
NOTE: Bearings are pre-packed with grease
.
DO NOT
clean with solvents as it will remove the
packing.

Refit bearings.
8.11.5 NOSE WHEEL REASSEMBLY
1.
Replace bearings in wheel hub.
2.
Apply automotive wheel rim lubricant to the tyre bead faces on the inside of the wheel rims.
Note that if this step is skipped disassembly of the wheel in future will be made much more
difficult.
3.
Position tyre and tube between wheel halves with tube inflation valve through hole in outside
wheel half.
4.
Mate wheel halves. While maintaining a light force, assemble a washer and nut on one through-
bolt and tighten snugly. Assemble the remaining washers and nuts on the through-bolts and
torque to the
“solid lamination” value specified in Table 1.
WARNING
Ensure tube is not pinched between wheel halves during assembly. Uneven or improper torque
of through-bolt nuts can cause failure of bolts with resultant wheel failure.
5.
Inflate tyre to seat the tyre beads, adjust to correct tyre pressure
