When aircraft broil in the summer heat on the flight line, oil heats up and
expands. If it has no place to expand, it will blow out rotor head seals. Then oil gets
on the rotor blades and on top of your aircraft. That makes the aircraft dangerously
slippery for anyone walking or working there.
When you service the oil reservoirs on the hub oil tank, the pitch bearing oil tank,
or the vertical hinge pin oil tank, rotate the blades. That levels off the oil in the sight
indicators so you can get a correct reading before you start filling reservoirs. Then
fill the reservoirs until the level reaches only halfway on the sight glass. That’s the
word in Tasks 1-55 to 1-57 of TM 55-1520- 240-23.
Looks
like you
need
more oil!
You’ve got
that
right. I Couldn’t
have said it
better, feebus!
F
illing a morning coffee cup to the brim is most mechanics’ recipe for a perfect
start to the day.
But filling the forward and aft rotor head oil reservoirs to the brim on a Chinook
is a recipe for ruining the rest of that day, mechanics.
If the oil reservoirs are low and need oil, fill ‘em no more
than half full.
Check all oil reservoirs

is enough
