M
echanics, make sure that all the bolts are installed in the engine lift brackets when
pulling a CAT engine from an ±MTV.
Lifting an engine with
any
bolts missing puts way too much stress and pressure on
the remaining bolts. Eventually, one or more of the bolts
that mount the bracket to the engine’s cylinder head
will shear or strip out, putting Soldiers at risk.
Replacing a damaged cylinder head
is expensive!
So, here are a couple tips to keep
in mind about the lifting brackets:
With all the bolts in place, the engine lift bracket can do its job. The end results are
safer shop practices and no downtime or rebuild costs.

When you remove the engine, make
sure you follow the engine assembly
replacement work packages in TM
9-2320-333-14&P and TM 9-2320-
391-14&P. Pay special attention
to Steps 23 and 24.
•
Make sure the lift bracket’s two
bottom bolts get reinstalled if
they’ve been removed.
Applying the grease doesn’t stop
the current flow, either. Just put
grease around the connectors and
just inside the connector lip.
There’s a note in WP 0033 00-11
of TM 9-2330-331-14&P reminding
you to do this.
This advice also applies to
other
tactical vehicles.

Also, consider adding the kit to
the official unit inventory so it
must
be checked
out and returned
after each use and
stays
intact.

get the rigs

won’t be
