lder vehicles like the M88A1 and AVLB may need to be lubed a little
more often than the LO indicates. That’s particularly true of their roadwheels
and road arms.
The LO calls for quarterly lubing, but that may not be often enough, especially
if your vehicle gets a good workout on a regular basis.
After operation, take a few minutes to check the roadwheels and arms. Hold
your hand close to each of the hubs and arm housings. If they’re too hot to touch,
chances are more lube is needed.
Of course, it
won’t matter
how much lube
you use if the
roadwheel
arm’s inner
and outer grease seals were installed wrong.
If the seals are in backward, any grease
you pump in leaks out of the arm and into
the hull. It won’t take long for the roadwheel
arm bearings to burn out.
Mechanics, remember to install the inner
seal with the lip facing away from the
vehicle’s hull. Install the outer seal with the
lip facing in toward the vehicle’s hull. That
keeps the lube where it’s needed.

Mine Clearing Blade . . .
rivers, there are only six lube points on each side of the mine clearing blade
on your M1-series tank. It doesn’t sound like much to remember, but far too
many blades are going down for lack of lube.
There are four lube points on each of the travel lock assemblies. The rest are at
the base of the lifting straps.
Give each of these lube points a good shot of general purpose aircraft grease
after every operation. NSN 9150-00-145-0268 brings a 6.5-lb can of the grease.
