8. Torque the tie bolt nuts to 90 inch-pounds for 1/4".
Observe the amount of torque required to turn the nut due to the locking friction of the nut and add
this to torque requirements to get the proper torque wrench reading.
9. Repack the bearings using MIL-G-81322 grease such as Aeroshell 22 or Mobil 28.
You may also use the newer Mobil SHC 100, but because it is not compatible with other wheel grease,
the bearings and races must be thoroughly cleaned before application.
10. With the wheel on a flat working surface, insert a wheel bearing. Lightly coat the bearing race with
bearing grease before installing the bearing.
11. Install the washers, felt grease seal and retention snap ring. A light coat of light weight oil on the felt
grease seal is recommended.
12. Turn the wheel over and repeat steps 10 and 11.
13. Place the wheel in a protective enclosure and inflate to 3.5 bar / 50 psi.
Reinstalling Wheel
1. Inspect the axle to ensure that it is clean, dry and in serviceable condition.
2. Slide the wheel onto the axle with the brake disc side inboard.
3. Install axle nut and hand tighten ensuring that that inboard wheel bearing is fully seated on the axle.
4. While slowly rotating the wheel, tighten the axle nut until resistance to turning is felt. Care must be
taken to ensure that the valve stem is not damaged during this process.
5. Loosen the axle nut only enough so that the wheel runs free, or with very little drag.
6. Align the axle nut to the nearest cotter pin alignment in the axle. If you need to move the nut for
alignment, first try to tighten it. If the wheel still moves with little or no resistance, use that alignment.
If there is significant resistance to rotation, loosen the nut to the next hole.
7. Install a new cotter pin. One end of the cotter pin should fold out and bend over the end of the axle to
its center. The other end should be bent back toward the wheel and shortened if necessary, to avoid
contact with the wheel.
CAUTION: Extreme care must be taken to ensure that the cotter pin does not interfere with the valve
stem or other parts of the wheel when the wheel is rotated!
8. Reinstall the brake caliper backing plate. Torque the bolts to the value indicated on the label of the
brake caliper and safety wire.
9. Rotate the wheel to ensure that it is secure and rotates freely.
10. Lower the airplane to the ground
11. Reinstall landing gear fairings and cowling as needed
