epairmen, your Chinook engine’s main oil filters are routinely replaced during
400-hour phase maintenance, but don’t just blow off the daily check of the oil filter
indicator buttons. Dirty oil filters can shut down your aircraft at any time, even in
the air.
If your bird works like a workhorse, your engine’s oil filters are working hard,
too. If the filters get clogged during operation, the oil filter indicator button pops out
to tell you it’s time to change the oil,
now
.
If the button is popped and daily inspections are ignored, clogged filters let dirty
oil pass through the engine system. That could damage engine bearings, then your
aircraft is down for extensive and expensive repairs.
So, if you want those engines to run
smoothly, inspect them every day, like it
says in Sequence 7.8 and 8.6 of TM 1-
1520-240-PMD. If the button is popped,
service your oil filter like it says in Task
1- 99 of TM 55-2840-254-23 on helicop-
ters with T55-L-712 engines and Task 1-
45 of TM 1-2840-265-23 on helicopters
with T55-GA-714A engines. That’ll
keep your engines from getting burned
by contaminated or dirty oil.
Looks like
everything
checks out!
Check oil filter indicator
for popped button
The moral of
the story is
“preventive
maintenance
saves
dollars.”
And those extra
dollars will
ensure that you
continue to have
“the
world’s
best
equipment”
and continue to
maintain it!
not so
fast,
buddy!
you’d better
check the
oil
filter indicator
button
on both
my of engines…
they won’t
run smooth
with cruddy
oil!
