WHEELS AND BRAKES
1. Nose Wheel Assembly (See Figure 1.)
A. Removal and Disassembly
(1) Jack the airplane enough to raise the nose wheel clear of the ground (refer to Jacking, 7-10-
00).
(2) To remove the nose wheel, first remove the cotter pin and washer that secures the safety clevis
pin of the wheel nut. Next remove the clevis pin and wheel nut. Then slide the wheel from the
axle.
(3) 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 wheel half
opposite the valve stem first and then removing the other half.
(4) 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 be removed by tapping out evenly from the inside.
B. Assembly and Installation
(1) Ascertain that the bearing cup for each wheel is properly installed. Install the tire with tube on
the wheel half with the valve stem hole and then join the two wheel halves. Install the through
bolts with the washers and nuts to the valve stem side.
NOTE: Torque the nuts on the Cleveland Wheel Assembly to 90 inch-pounds. Torque the nuts
on the McCauley wheel assembly to 140-150 inch-pounds on the McCauley wheel
assembly only. A bushing is required to prevent tube movement.
(2) Lubricate the bearing cones and install the cones, grease seals, felt rings and seal retainer
rings. Secure with snap rings.
