TAIL WHEEL REMOVAL AND DISASSEMBLY

To remove and disassemble tail wheel/tire, proceed as follows: (See Figure 6-1)
A. Using a suitable Jack. Jack and secure tail of aircraft, using provided jackpoint.
B. Remover dustcover (hubcap) and deflate tire by depressing the schrader valve
stem plunger until air can no longer be heard escaping from the tire.
C. Remove schrader valve core.
D. Remove cotter pin and axle castellated nut. Rock wheel/tire slightly, then remove
wheel/tire assembly from axle, and be sure to capture the two- (2) P/N95435-11
spacers, located on each side of wheel assembly.
E. From each side of wheel; carefully remove snap ring, felt grease seal retainer,
felt grease seal, grease seal ring and cone bearing. Store the cone bearings.
Label the bearings for reinstallation into position from which it was removed.
F. With the tire completely deflated, removing the wheel through-bolts will separate
the wheel halves. Pull the wheel halves from the tire by removing the wheel half
opposite the valve stem first. Mark wheel halves to note relationship to each
other for reassembly.
A. Visually check all parts for cracks, corrosion, distortion, defects and excessive
wear.
B. Inspect felt grease seals. Replace if surface is hard or contaminated, or shows
evidence of excessive wear. Lightly saturate grease seal felts with SAE 10wt. Oil
(3-in-ONE oil) (do not soak).
C. Inspect tire for cuts, anomalies, internal damage and deterioration.
D. Inspect inner tube for cuts, wrinkles, anomalies and deterioration. Note: Do not
use a used inner tube with a new tire. Tubes grow in service, taking a permanent
set of about 25% larger than original size. This makes a used tube too large to
use in a new tire, which could cause a wrinkle and lead to tube failure.
E. Inspect wheel bearing grease for contamination and solidification at each
periodic inspection. Repack bearings with MIL-G-81322 (Aeroshell 22) or
equivalent grease. Note: Do not exceed 500 wheel miles or on annual inspection
whichever comes first between repacking intervals.
F. Clean and inspect bearing cups and cones. Note: Do not spin dry bearings or
handle bearing components with bare hands. The bearing cup should not be
removed except when replacement is necessary due to scratches, nicks, pitting,
spalling, corrosion, brinelling, or evidence of overheating. Note: If bearing cup is
replaced, its companion bearing cone must also be replaced.
