________________________________________________________________________
REPLACEMENT OF MAIN WHEEL
1. Hoist aircraft up. This can be done by placing a floor “jack” under main gear near
fuselage.
2. Remove the cotter pin and axle nut, disassemble the brake assembly and remove the
wheel and tire.
Check the wheel casting for visible signs of cracks, corrosions, loose or broken bolts,
and any defects which may impair its operation.
Note: If there are any indications of defects, deflate the tire, remove the three
wheel bolts, remove the tire and tube and perform a thorough inspection of the
suspicious area..
Remove wheel bearings from the wheel hub and clean thoroughly with a suitable
solvent. When repacking with grease, be sure the lubricant enters the space between the
rollers in the retainer ring. Do not pack the grease into the wheel hub.
REINSTALL in reverse order, using the shims to prevent lateral floppiness. Safeties the
nut. Note: Bolt torque values are given in AC-43-13-1B. Perform Landing gear section of
Table 1.
BRAKE MAINTENANCE
BLEEDING PROCEDURE
If the brake line has been disconnected for any reason, it will be necessary to bleed the
brake and line as described below.
Connect the bleeding unit hose to the fitting at the bottom of the brake unit and pressure
fill the brake system with MIL-H-5606 fluid.
Remove the bleeding unit hose after tightening the fitting.
Repeat the bleeding procedure on the other gear.
BRAKE PADS REPLACEMENT
When the brake pads become worn excessively (1/16” pad thickness), they are replaced
with new pads.
Remove the wheel (see previous pages).
Remove the two bolts holding the pads.
Remove the pads.
REINSTALL in reverse order. Check for safeties and operation.
Note: - No adjustment of brake clearance is necessary on the brakes.
- The brake disc should not necessarily be replaced because of circumferential
grooving.
Perform Landing gear section of Table 1.
