INSPECTION OF MAIN WHEEL ASSEMBLY.
Inspect brake disc for cracks, excessive wear or scoring, rust, corrosion and warpage. Remove rust and
blend out nicks, using fine 400 grit sandpaper. Replace disc if cracked or when disc is worn below minimum

with if applicable. In addition also perform the same inspection given for nose wheel.

paper.
Wheels may also be repainted if the parts have been repaired and thoroughly cleaned. Paint exposed areas
