ASSEMBLY AND INSTALLATION OF MAIN WHEEL. (Refer to Figure 32-13.)
1. Ascertain that the bearing cup for each wheel is properly installed. Install the tire with tube on the
outer wheel half and then join the two wheel halves. Position the brake disc in the inner wheel half and install
the through bolts with the nuts on the valve stem side. Torque wheel nuts to 150 inch-pounds and inflate tire.
2. Lubricate the bearing cones and install the cones, grease seals, seal retainer rings and felt rings. Secure
with snap rings.
3. Slide the wheel on the axle and secure with retainer nut. Tighten the nut to allow no side play, yet
allow the wheel to rotate freely. Safety the nut with a cotter pin and install dust cover.
4. Position the brake lining back plates between the wheel and brake disc and the brake cylinder on the
torque plate. Insert the spacer blocks between the back plates and cylinders, and install the four bolts to secure
the assembly. If the brake line was disconnected, reconnect the line and bleed the brakes.
BRAKE ADJUSTMENT AND LINING TOLERANCE.
No adjustment of the brake lining clearance is necessary as they are self-adjusting. Inspection of the lining
is necessary, and it may be inspected visually while installed on the airplane. The linings are of the riveted type
and should be replaced if the thickness of any one segment becomes worn below .100 of an inch or unevenly
worn.
