pache maintainers, Para 10.1 in TM 1-1520-238-23-6 tells you to inspect
both engine fuel filter elements and the filter bowls for contaminants after doing
run-ups on your aircraft. But removing the fuel filter from its bowl can be a real
exercise in damage control.
Para 6-46 in TM 1-2840-248-23 tells you to remove the filter element, NSN
2915-01-094-8577, from the bowl but doesn’t say how.
If you’ve been putting a screwdriver to the filter to pry it out of the bowl,
stop
!
You’ll damage the threads on the bowl’s shaft and on the fuel filter element and
seal. Then the filter has to be replaced.
The best way to remove the filter without damage is with an engine fuel
AH-64A . . .
4.
During reinstallation, hand tighten
the bowl only.
3.
Tap the tool on a hard surface and
the filter will fall out.
2.
Screw the removal tool shaft onto
the threaded shaft in the bowl. (Make
sure tool is clean. Clean with a lint-
free cloth before use.)
Here’s how to use it:
1.
Remove the bowl and filter element
from the engine.
