Wheels
(refer to on-aircraft inspections presented in the latest edition
of Cleveland Wheels & Brakes Maintenance Manual and
Service Bulletins for wheel, tire and break inspections)
O O 1 Visually inspect the wheels for corrosion, cracks, or other
visible damage.
O O 2 Check wheel nuts to be sure they are properly installed and
have not worked loose. Bolt threads should be flush to 1-1/2
threads extending beyond the nut. Nuts should be on the side
of wheel opposite the brake disc (outboard side of wheel).
O O 3 Inspect the brake disc for rust, excessive grooves, large
cracks, coning or other visible damage. Check if disc thick-
ness is more than 0.325in/8.255mm. Coning of disc in excess
of 0.015 in /0.381 mm is cause for replacement (see Fig. 5).
O 4 Remove wheels and wheel bearings. Inspect wheel bearing
grease for contamination and solidification.
O 5 Inspect snap rings and grease seals for distortion or wear.
Replace grease seal felts if they are hard or contaminated.
Lightly saturate grease seals should be replaced if cracked,
dried out, or distorted.
O 6 Inspect wheel bearings for excessive wear or damage. Re-
place on condition.
O 7 Repack bearings with AEROSHELL 22C (per MIL-G-81322),
or equivalent. Reinstall wheels and safety.
O O 8 Check wheel bearing clearance and wheels for free rotation.
Tires
O O 1 Visually inspect tires for cuts, flat sports, and tread or side
wall damage. If changing of tires is necessary follow the
instructions, including off-aircraft inspection of wheels,
presented in the Cleveland Wheels & Brakes Component
Maintenance Manual.
O O 2 Check inflation pressure (2.6 bar /38 psi). Proper inflation
will provide maximum tire and wheel life.
