Dear Editor,
After pulling the powerpack in your M88A1 recovery vehicle, the final
drives are left uncovered. That means dirt, sand, water and other
debris have full access to the final drives.
One way to protect final drives is to cover them with plastic bags and
tape. But the bags are easily torn and tape leaves behind a sticky
residue that’s hard to clean up. Too many mechanics take their chances
and leave the final drives
completely unprotected.
We’ve designed a
homemade final drive cover
that’s easy to use and
keeps dirt out.
Here’s what yor support
needs to make the covers:

Looks like you’ve finally got those drives covered! Good work! This drawing will
be added to the special tools list in TM 9-2350-256-20 at the next update.

ppendix B in TM 9-2350-256-10 gives you the option of a 12x12-ft tarp,
NSN 2540-00-653-7589, or a 12x17-ft tarp, NSN 8340-00-841-6456, to help
protect your M88A1 recovery vehicle from the elements. Which one should you
choose?
In this case, more is better. The 12x12-ft tarp
doesn’t cover enough of the top of your vehicle,
especially the boom tubes. Rainwater falls straight
down the boom tubes and fills the hull.
Even if you drain the hull regularly, some of
that water is going to evaporate—and condense
right onto the main winch and the hoist winch
drum. That gives rust a foothold.
So always order the 12x17-ft tarp. It’s big
enough to cover the boom tubes and keep rain-
water out.
