(c) Position tire and tube on wheel half ensuring valve stem protrudes from hole in wheel half.
(d) Place wheel half in proper alignment position with opposite wheel half and apply light force
to mate the wheel halves together. Do not pinch tube between wheel halves.
(e) Install nuts, washers, and bolts.
(f) Torque nuts to 90 inch-pounds (10.2 N.m.).
CAUTION: Uneven torque of nuts can cause bolt failure with resultant wheel failure.
(g) Inflate tire and adjust pressure. (Refer to 12-10)
(h) Clean and repack bearing cones.
(i) Install bearing cones and grease seals into wheel halves and secure with snap rings.
(4) Installation - Nose Wheel, Tire, and Tube
(a) Insert axle and spacers into wheel and tire.
(b) Position wheel into fork so that valve stem is on left side of airplane and install washers,
axle bolt, and nut.
(c) Torque axle nut to 150 inch-pounds (16.9 N.m.) to seat bearing.
(d) Back off axle nut to zero torque.
(e) While rotating wheel, retorque axle nut to 20-40 inch-pounds (2.2-4.5 N.m.) and install cot-
ter pin. Wheel should spin 1-2 revolutions when spun by hand.
(f) Inflate tire. (Refer to 12-10)
(g) Remove airplane from jacks (Refer to 7-00)
(h) Install nose gear fairing. (Refer to 32-20)
(5) Inspection/Check - Nose Wheel Inspection
(a) Disassemble wheel. (Refer to 32-42)
(b) Inspect wheel halves for cracks, corrosion, or other damage. Areas with suspected cracks
should be dye-penetrant inspected. Cracked or badly corroded parts must be replaced.
Small nicks, pits, and scratches may be polished out with fine 400 grit wet or dry sandpa-
per.
(c) Inspect bearing cups for looseness, scratches, pitting, corrosion, or evidence of overheat-
ing. Replace cup if any defect exists.
(d) Inspect snap rings and grease seals for distortion or wear. Replace grease seal felts if
contaminated or hard.
(e) Carefully inspect through bolts. Check for cracks by magnetic particle inspection, espe-
cially in radius under head and in threads adjacent to bolt shank. Replace any doubtful
bolt.
(f) Inspect self locking nuts for damage. Replace nut if doubtful.
(g) Reassemble wheel. (Refer to 32-42)
