id you know the maximum cargo load for M871 and M871A1 semitrailers is
45,000 pounds? If you overload, poorly distribute loads, or abuse those semitrailers
in any way, they could crack under the pressure. And cracks or separations in your
semitrailer’s rear suspension system make your semitrailer
NMC!
TACOM SOUM 10-017 told commanders to have all M871 and M871A1
semitrailer trunnion mount brackets inspected at the frame weld area for cracks and/
or separations using TB 9-2510-242-40 as a guide. That’s because cracks have been
found in the trunnion mount bracket assembly area that attaches the suspension and
the axle to the frame. In fact, the welds on some semitrailers are
completely
cracked,
separating the trunnion from the frame. This could lead to complete separation of the
rear suspension and axle from the semitrailer!
Don’t repair cracks
if you Fnd them because
the M871 & M871A1
semitrailers are on the
automatic disposal list. Just
turn your unserviceable
semitrailers in to DLA
Disposition Services
(formerly called the
Defense Reutilization
and Marketing OfFce or
DRMO). Then order a
replacement, if authorized
by your unit’s TOE.
By the way, a trunnion mount inspection is now part of the crew/operator’s
BEFORE PMCS. Pencil in this change to TM 9-2330-358-14&P.
