a. With cowlings removed, locate bushings on lower cowling. (See Figure 8A-3a.)
b. Using snap ring pliers, remove snap ring and old bushing.
c. Install new bushing and new snap ring.
NOTE
Bushings should be inspected each 100 hours and should be
replaced upon condition, but no later than 500 hours time in
service.
d. Locate pins in upper cowling.
NOTE
It should not be necessary to replace the pins unless bushing in
lower cowling has worn enough to allow damage to the pin. Any
noticeable notching or cutting of the pin requires replacement.
e. If it is necessary to remove the pins, appropriate tools should be used to remove the fiberglass resin
from around the pin and plate assembly. (A template or adequate measurements should be made to assure
proper alignment of the new pin and plate assembly.)
f. Remove pin and plate assembly
g. To install new pin and plate assembly it will be necessary to prepare the fiberglass surface to accept
the new plate. (See Paragraph 4-56, FIBERGLASS REPAIRS.)
1. Clean area as required, and roughen.
2. Prepare cowling surface by applying resin. Do not allow to harden.
3. Install plate and pin.
4. Lay in a layer of resin impregnated fiberglass cloth over the plate and surrounding fiberglass. (Use
template or measurements from step e to assure alignment.) Allow to cure.
