Do
you
have
gas?
You
should have traded in your old
gas-powered M12A1 by now
for a new diesel one. If you still
have the gas version, the Army
wants to know about it. Please
contact TACOM-SBC’s Barry
Lakes at DSN 793-5536, (309)
782-5536, or email

He will provide disposition
and shipping instructions for
your M12.
Diesel differences.
The diesel
model
has
differences
from
the gas model that you need
to remember. With the diesel
version, you don’t need to remove
all
the
engine
compartment
panels. Just the back one will do.
But don’t forget to open it for
operation. Otherwise the exhaust
has no place to go.
Changing the oil is much easier
with the diesel model, so now
you don’t have a good excuse
for not doing it. Change the
engine oil after the Frst 20 hours
of operation or at the end of the
Frst month after you receive the
M12. After that, change the oil
every 200 hours of operation or
annually, whichever comes Frst.
The oil from the diesel drains
slowly and it may take two hours
to completely drain it. Use the
dipstick to check the oil levels
when draining and Flling.
Valves and such.
The set-
screws for the four valves often
work loose (or are left off at
maintenance). That makes the
valve
difFcult–or
impossible-
to turn with the handle and the
handle can actually come off. If
the valves handles feel loose, tell
your repairman. He can tighten
or install setscrews.
When you do quarterly lubing,
make sure to hit Valve #1 with
GAA. If it doesn’t get lubed, it
often breaks. In fact, if any valve
feels stiff, give it a shot of GAA.
Watch the heat!
Make sure the heater exhaust is uncovered and that you keeps
hoses and electrical cables away from it. The exhaust reaches 200°±, which can melt
lots of things, including you. So be careful.
