etting things wet that you meant to keep dry can be a problem if your FMTV’s cargo
cover is ripped. Avoid this by doing one smart action: PMCS!
Check for holes and tears in your truck’s cargo cover
before
moving out on a mission.
Then plug up any that you see. Patch them with repair kit, NSN 2540-01-496-4442. That
should solve your problem while keeping cargo dry and you comfortable.
Cargo Cover Repair
The repair kit mends
vinyl-coated
cargo covers. Don’t use it on canvas because it wasn’t
made for that. The kit comes with an instruction card, alcohol pads for cleaning the vinyl,
scissors and a roll of repair tape.
Here’s how to use it:
Seam Repair
If rain gets in after you’ve repaired your truck’s canvas cover, you may need to seal the
seams. Apply sealant to the seams using a small brush. A pint of sealant comes with NSN
8040-00-262-9028; NSN 8040-00-281-1972 brings you a gallon.
Keep the Bed Dry
Standing water in the
dump
bed
means
the
drain holes are clogged.
Ignore the standing water
long enough and you’ll
have a rusted bed.
Eyeball the bed corner
drain holes for debris.
If
you
Fnd
plugged
holes, turn the tip of a
screwdriver through the
holes to open them up.
If your dump truck is going
to sit for a while (like weeks
or months), keep the bed
elevated so water can easily
drain. Use the dump body
support
braces
(bedlocks)
to
hold
the
bed
up
and
keep pressure off the main
hydraulic cylinders.
•
Make sure your cargo cover is dry and is placed in an area that is 50°F or higher.
•
Find the hole or tear on the inside (or
underside) of the fabric. Make all repairs on
this side.
•
Let the fabric dry.
•
Spread the fabric on a flat surface.
•
Cut the tape two inches longer than the hole you want to cover.
•
Using the scissors, round off the four corners of the tape. Rounded corners make the
tape less likely to peel off.
•
Peel off the film liner from the tape as you apply it to the inside of the fabric.
•
Press the tape firmly against the fabric. Allow the tape to set, the longer the better.
Overnight is best, but give it at least 20 minutes.
Keep ‘em Lubed
With the dump bed up, lube the grease Fttings
for the bed rollers during scheduled services. Lube
keeps the rollers moving smoothly when the bed
is elevated. Also, put a
thin
layer of grease on the
roller tracks for smooth operation. If you use too
much grease it’ll just get squished out and wasted
the Frst time the rollers move across the track.
Get the Hook
Lube both grease Fttings
on the safety latch hook
during scheduled services.
Without lube, the hook can
freeze in place. Then it—or
the latch mount—will break
when you raise the bed.

Brush off loose soil or dirt from the area to
be taped. Clean the area with an alcohol
pad. Wipe a large enough surface so that
the tape will fit well inside the cleaned area.
