Self-locking nuts used in aircraft are
precision-made so never try to restore
one with a locally-made tool, like the
one shown on page 55 of PS 194. Use
a new nut.


 Die-Alco- MX
 Yes you can winterize your multi-
fuel, diesel and gasoline fuel systems
with alcohol during freezing tempera-
tures. Use '/2 pint of Grade III, Spec 0-E-
760B denatured alcohol FSN 6810-543-
7415 (1 Gal can) to every 10 gallons of
fuel. Although some tech manuals
haven't been updated to reflect this new
poop, USATACOM Msg 1-23033 (23
Jan 68) says it's OK. Regardless of the
alcohol mix, be on constant guard
against water getting into your system.
Keep it water-free.




 The bit in PS 192, page 19, about us-
ing 4 steel bolts andassociated hardware

housing also goes for the Huey UH-1C
model. Dig up a copy and make a note.


 Change 3 to your 155-MM towed
howitzer's TM 9-1025-200-12 says you
should jack up your M114A1 till the tires
are off the ground when you're putting
it in firing position. Fine. But watch this:
If you have to extend the firing jack
plunger all the way to get those tires air-
borne, slow down in your cranking when
you near the limit. Else you might hurt
the firing jack stop.



 No need to play with fire because the
gasket on your gas can is lost or in bad
shape. You can replace it with a syn-
thetic rubber gasket, Type Ill, FSN 5330-
298-7165. TB 385-3 (Jun 68), Fire Pre-
vention and Protection, Military Gaso-
line Cans, gives you the authority.



 Now, just a cotton-pickin' minute
there! Don't wrap a cleaning patch
around your brush when drying the bore
or chamber of small arms. It won't get it
any drier and it's likely to ruin the
brush. Use the swab holder section of
your cleaning rod that's what it's for.
