t’s real easy to damage the engine’s throttle linkage and
mounting bracket when you tilt or lower the small emplacement
excavator’s cab.
Both the linkage and bracket
are connected to the driver’s side
of the cab’s engine wall. There’s
not much room between them and
the engine. A damaged throttle
linkage means you’re stuck with
an engine that won’t accelerate or
decelerate smoothly, if at all.
To protect the linkage and
bracket, have a buddy hold the
other side of the cab when it’s
tilted forward or back. That extra
help keeps the cab clear of the
linkage.
Pages 4-418 through 4-432 of TM 5-2420-224-20 have the
complete lowdown on how to raise and lower the cab.
Looking for Leaks
And while you’re looking for leaks
during PMCS, touch the return line
where its multiple-connector mounts
into the engine block. If it feels wet,
the metal O-rings on each side of the
connector are probably shot.
Replace them with NSN 5330-00-
140-7701. They’re shown as Item 2 in
Fig 40 of TM 5-2420-224-24P. For a
tight seal, use the O-rings only once.
Watch the Fuel Line
The excavator’s fuel return line is an
open target for bumps and rubs when
you remove and replace the engine cover
(doghouse) during checks and services.
Over time, enough bumps and rubs wear
a hole in the line. You’ll know something’s
up when the engine runs rough, won’t run
at all, or you smell fuel inside the cab.
You can head off those problems by
lifting the cover clear of the fuel return line
when you need to get at the engine.
U
nits, you need to move the camoufage net systems listed in the table below From
your Modi±ed Table oF Organization and Equipment (MTOE) to the Common Table
oF Allowances (CTA) 50-909.
Note that this is only a transFer oF material From the MTOE to the CTA. When some
oF you saw these camo nets come oFF your unit’s MTOE, you tried to turn them in! Not
so Fast. Keep any on-hand net systems unless otherwise instructed by higher HQ.
Note:
Only the ±rst two LINs listed are still active. The other LINs are terminal
items that are still good, but are no longer stocked or procured. The old nets will keep
their LINs/NSNs For property book purposes.
