8.11 ENGINE AIR FILTER
The wet-type polyurethane foam air filter must be inspected at least once every fifty hours. Under
extremely adverse operating conditions, it may be necessary to inspect the filter more frequently. The filter
is disposable and inexpensive and a spare should be kept on hand for a rapid replacement.
(a)
Removal Of Engine Air Filter
The filter is located in the lower right front of the engine compartment and may be removed
by the following procedure:
(1)
Open the right side of the engine cowling.
(2)
Loosen each of the four quarter-turn fasteners securing the air filter cover.
(3)
Separate the cover and remove the filter.
(4)
Inspect the filter. If it is excessively dirty or shows any damage, replace it immediately.
(b)
Installation Of Engine Air Filter
When replacing the filter, install the filter in the reverse order of removal.
8.13 BRAKE SERVICE
The brake system is filled with MIL-H-5606 (petroleum base) hydraulic brake fluid. The fluid level
should be checked periodically or at every 50 hour inspection and replenished when necessary. The brake
reservoir is located on the fire wall in the engine compartment. If the entire system must be refilled, fill
with fluid under pressure from the brake end of the system. This will eliminate air from the system.
No adjustment of the brake clearances is necessary. If after extended service brake blocks become
excessively worn, they should be replaced with new segments.
