ou’ll be asking “What gives?” when the SEE’s backhoe stays in the transport
position after you pull the lock’s release lever.
When that happens, take a look at the release
lever’s pull cable where it mounts into its bracket
between the rear cab window and spare tire.
Vibration loosens the mounting bracket nuts and
lets the cable slide out. So, nothing happens when
you pull the release lever. Since the lock won’t
release, you can’t move the excavator’s backhoe
into the upright position for digging operations.
If the travel lock on your SEE won’t release, eye-
ball the cable where it fits into the mounting brack-
et. If the nuts are loose or the cable has slipped out
of the bracket, report it to your mechanic.
A
n oil leak from the sight indicator gauge on
either of the SEE’s hydraulic tanks usually
means the screws that hold the gauge in place
were overtightened.
Too much muscle on those screws will crush
and split the rubber gasket behind the sight indi-
cator. Then oil seeps past the gasket and runs
down the side of the tank.
So easy does it, repairmen. The screws should
only be snugged down by hand. If the gasket is
leaking, replace it with NSN 6680-01-144-8984.
It’s part of the sight indicator assemblies shown
in Figures 317 and 318 of TM 5-2420-224-24P.

Dear Half-Mast,
Our
units
just
got
some new excavators.
They had small protective
caps on the grease fit-
tings. These caps keep
the fittings clean and
unclogged
during
field
exercises. It's easier to
take the cap off when
it's time to lube than it is
to replace the fittings
because they won't take
grease. Can we get more
of these caps for other
construction equipment?
SFC S.M.F.
Dear Sergeant S.M.F.,
Caps are put on some equipment during
manufacture. Other construction equipment
gets them during rebuild to protect them against
paint and dirt during that process.
Protective caps keep dirt
out of grease fitting
Put your
slings,
cables
and
chains
in my
stowage box!
They weren't
intended to be
replacement items,
but if they're doing
the job, use 'em. You
can get more with
NSN 4730-00-289-
8148.
Y
ou're not done with your
crane, operators, until you've
done your "good housekeeping."
That is, never leave the crane's lift-
ing slings, cables, chains or pile drive
attachments on the vehicle's super-
structure when you're done with
them. Anything left out can get lost
when the crane moves, or cause you
to slip and fall off the vehicle.
Put the items where they belong—
in the stowage box next to the cab
carrier—so they're out of the way,
won't get lost, and you'll know where
to find them.
