echanics, you all know that rust and metal don’t mix. That’s especially true with the
spare roadwheel hanging on the side of your M88-series recovery vehicle.
The spare roadwheel is bolted to
the side of the vehicle at an angle, just
hanging around waiting to be used.
But that leaves it exposed to rain and
washwater, which pools in the bottom of
the roadwheel until it evaporates.
Standing water doesn’t do the spare
roadwheel any favors. The bottom of
the roadwheel can develop severe rust.
And the lug nuts can rust in place on the
mounting bolts. Then the bolts can snap
when you try to remove the nuts.
But just a little elbow grease will make
sure your M88’s spare roadwheel is ready
to bail you out of a jam when needed.
Use a little antiseize compound on the lug nuts and bolts when mounting the road-
wheel. That’ll prevent rust and make the nuts easier to remove later. Get a 4-oz tube of
antiseize compound with NSN 8030-00-059-2761.
Be sure to take a few rags and soak up the pool of water in the bottom of the roadwheel
after it rains or you’ve washed your vehicle. That’ll keep the rust at bay and the spare
roadwheel ready for action.
Better yet, if you have access to a canvas shop, get them to make a cover for the
roadwheel. That’ll keep water at bay all the time.

rewmen, your M119A3 howitzer’s fre control computer (FCC) is wrapped in a
hard case designed to protect its sophisticated components ±rom damage.
But the FCC’s ±ragile touch screen is still its weak spot. A replacement FCC, NSN
1220-01-604-0729, will set your unit back nearly $27,000!
So take care to protect the FCC’s touch screen, especially during missions when
it’s exposed to the elements.
When using the FCC outside o± its docking station, don’t drop it, lay it down on
the screen or use anything except the stylus that came with it on the touch screen.
