WHEELS
1. DESCRIPTION
The main wheels are of aluminum construction and designed to be used with tires and tubes. Each main
wheel consists of two wheel halves, two bearing cups, two bearing cones, grease seals, a brake disc
assembly, and a snap ring. The wheel halves are joined with bolts, washers, and nuts. A hole in one wheel
half provides for valve stem installation. The 15 x 6.00 x 6 wheels use 6-ply-rated tube tires and rotate on
two bearings protected against contamination by grease seals. The wheel is secured to the axle with a nut,
and cotter pin.
The nose wheel is of aluminum construction and designed to be used with tires and tubes. The nose wheel
consists of two wheel halves, two bearing cups, two bearing cones, grease seals, and snap rings. The
wheel is joined by bolts, washers, and nuts. A hole in one wheel halve provides for valve stem installation.
The 5.00 x 5 wheels use a 6-ply-rated tube tire and rotate on two bearings protected against contamination
by grease seals. The wheel is free castering on an independent axle and is used to steer the airplane on
the ground by means differential brake application.
2. MAINTENANCE PRACTICES
A. Servicing Tires and Tubes (Refer to 12-20)
B. Main Wheel, Tire, and Tube (See Figure 32-411), (See Figure 32-412)
(1) Removal - Main Wheel, Tire, and Tube
(a) Remove main gear fairings. (Refer to 32-10)
(b) Raise airplane on jacks. (Refer to 7-00)
(c) Remove brake assembly. (Refer to 32-10)
(d) Deflate tire and tube completely.
WARNING:
Do not attempt to remove valve core until tire has been completely deflated.
The valve core will be ejected at high velocities if unscrewed before air pres-
sure has been released.
(e) Remove valve core.
(f) Remove cotter pin from axle and remove axle nut
(g) Remove wheel/tire assembly from axle.
(2) Disassembly - Main Wheel, Tire, and Tube
WARNING:
Injury can result when attempting to separate wheel halves with tube
inflated. Care must also be taken to avoid damaging wheel halves when
breaking tire beads loose.
(a) Separate tire beads from wheel halves by applying even pressure around the entire side-
wall of the tire.
(b) Remove nuts, washers, and bolts holding wheel halves together.
(c) Mark wheel halves to note relationship to each other for reassembly.
(d) Separate inner wheel half and outer wheel half
(e) Remove tire, tube, and brake disk.
(f) Remove snap rings, grease seals, and bearing cones from wheel halves.
