ransmission oil belongs in your tank’s
transmission, not sprayed all over the engine.
Unfortunately, the filler neck is so small
that spills often happen. A lot of that spilled
oil gets blown by the cooler fans onto the oil
cooler fins.
That oil residue attracts dirt and dust like
a magnet. The gooey mess that forms on the
cooling fins won’t let the heat radiate away
from the oil inside the coolers. That results
in transmission damage.
Never add oil without a funnel. If your
tank’s oil funnel tip is broken or too large for
the transmission filler opening, get a new
funnel.
A flexible funnel does the best job. NSN
7240-00-559-7364 brings a box of 12.
Each funnel holds one quart, so use it
carefully. Don’t pour more than a quart into
the funnel at one time or it’ll overflow. If that
happens, make sure you wipe up any spilled
oil right away.

M1-Series Tanks…
Don’t Forget the Tank
Now that you’ve got the mine clearing blade checked out, don’t forget the tank it’s
attached to.
The blade’s weight puts a lot
of extra stress on your tank’s
suspension system, so check
the shock absorber housings
for leaks each time you stop. If
the fluid level is low, add lubri-
cating oil, NSN 9150-01-439-
0756,
until it reaches the
halfway point in the sight glass.
Never park your tank with the mine blade in the travel position for an
extended period. Lower the mine blade to the ground.

Lifting Belts
Take care of the mine clearing blade’s lifting belts and they won’t let you down.
That means using the right lifting techniques.
During operations, always make sure you back the vehicle 8-10 feet before lifting
the blades. That keeps the blades from hanging up on anything that’ll snap the belts.
Never use the mine clearing blade
to recover mired vehicles or to lift
anything. Either the lifting belts will
break or the motors will burn out.
Never drive the blade through
concertina wire. It’ll nick and cut
the belts. When that happens, your
mechanic has to replace them with
new belts, NSN 4020-01-289-8249.
Lubing
There are only five lube points
on each side of the mine clearing
blade, but they still get missed.
There are four lube points on
each of the travel lock assem-
blies. The other is at the base of
the lifting straps.
Give each of these lube points
a good shot of general purpose
aircraft grease after every opera-
brings a 5-lb can of the grease.
