T
he M1-series tank’s transmission fller neck doesn’t have a very big opening,
mechanics.
How small is it? Well, let’s just say it’s too small to try pouring transmission fluid
directly From the can.
No matter how careFul you are, some oF
that fluid is going to spill. When it does,
the oil cooler Fans are going to blow it all
over the cooling fns on the oil coolers.
That oil residue attracts dirt and dust like
a magnet. The gooey mess that Forms on
the cooling fns won’t let the heat radiate
away From the oil inside the coolers. That
results in transmission damage.
So, never add oil without a Funnel. IF
your tank’s oil Funnel tip is broken or too
large For the transmission fller 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.
M
echanics, when you remove the powerpack on an M113-series vehicle, you’ll feel mighty
foolish if the carrier goes rolling off across the motorpool.
Once you disconnect the Fnal drives, that vehicle is free to go where gravity takes it. And
a free-rolling vehicle is bad news for everybody and every thing that stands in its way!
Head off serious injury to others and damage to the vehicle by always chocking both
tracks. Here’s how:
•
Make sure the vehicle is on a hard, level surface to lessen the chance of rolling. That
also lowers the risk of damage to the hull and powerpack when you lift it out.
•
Slide a block of wood or other suitable object between the track guides and roadwheels.
Make sure the chock block extends the full width between
both
roadwheels.
Just don’t forget to remove the chock blocks once the powerpack is reinstalled.
Otherwise, your next repair job will be to the tracks!
M1-Series Tanks…
Keep Oil Where it Belongs
M113-Series ±OV…
hey,
I don’t
ask for all
that
much!
just a little
consideration
when it’s time to
fill me with
oil!
a
flexible
funnel
would
be nice!
Spilled oil ends up on cooling Fns
±lexible
funnel will
prevent oil
spills
Place chock block between these two roadwheels on both sides of track
come
back!
I’m not
finished with
you yet!
you should’a
remembered to
use chock blocks!
