Figure 32-13. Main Wheel Assembly
REMOVAL AND DISASSEMBLY OF MAIN WHEEL. (Refer to Figure 32-13.)
1. Place the airplane on jacks. (Refer to Jacking, Chapter 7.)
2. To remove the main wheel, remove the four cap bolts that join the brake cylinder housing and the
lining back plate assemblies. Remove the back plate from between brake disc and wheel.
3. Remove the dust cover and the cotter pin that safeties the wheel nut, remove the wheel nut and slide
the wheel from the axle.
4. The wheel halves may be separated by first deflating the tire. With the tire sufficiently deflated,
remove the wheel through bolts. Pull the wheel halves from the tire by removing the inner half from the tire
first, and then the outer half. The brake disc may be removed at this time.
5. The wheel bearing assemblies may be removed from each wheel half by first removing the snap rings
that secure the grease seal retainers, and then the retainers, grease seals and bearing cones. The bearing cups
should not be removed only for replacement and may be removed by tapping out evenly from the inside.
INSPECTION OF MAIN WHEEL ASSEMBLY.
The inspection of the main wheel is the same as the inspection given for the nose wheel.
