Dear Editor,
On M939-seRes trucks, the AOAP samplng vaLve for the engine oiL
is right above the
aLte±ator. It's easy
to spi²L oiL on the
aLte±ator³a mess
and a fire haza´µ
So, we've a¶ an
18-in piece of ·¸in
ID tubing, NSN
liI
to the vaLv¹.
It's
Listed in the buLk
materiaLs on Page
840 of TM 9-2320¸
272¸20P.
When it's time foº a sampLe» start the engine and drain about a
pint of oiL into a cLean container to Fush the Line. Then take your
oiL sampLe. Shut off the engine, and pour the pint of oiL back into
the engine.
