Trucks…
M66 Mount Yes-- M36 Mount
No
I
f any of your trucks have the M36 machine gun ring mount, they shouldn't
have. The M36 is history—it's discontinued and should be turned in to your
local demil facilities or reclassified as an M66 ring mount, depending on
which version of the M36 you have.
If your M36s are NSN 1005-01-099-
5205 or NSN 1005-01-099-5206, they
should be reclassified on your property
book as M66 ring mounts under LIN
M74364. All other M36s should be
turned in.
All trucks except the M939 should
be using the M66 ring mount, NSN
If you're unsure how to mount the
M66, check your vehicles' -20P TMs.
They list the parts and kits required for
mounting the M66. Mounting instruc-
tions come with the kits.
M809-series 5-ton:
mounting kit, NSN 1005-01-226-4589, and cab reinforce-
ment kit, NSN 2590-01-322-2694. See Fig 513 in TM 9-
2320-260-34P-2 for info on the M809's three-post mount.
M35-series 2 1/2-ton:
mounting kit,
NSN 1005-01-226-4589, is used
on both the M35A2 and M35A3.
FMTV:
mounting and reinforcement kit,
NSN 1005-01-381-5431
M977-series HEMTT:
mounting kit, NSN 2590-01-220-6377
The cab reinforcement kit, NSN 2590-01-322-2694, is
needed for the M35A2 only. The M35A3 already has
cab reinforcement installed. See Fig 306 in TM 9-
2320-361-34P for info on the three-post mount kit
and Fig 318 for info on the cab reinforcement kit.
If you don't install the reinforcement kit
when you install the M66, the mount's
weight cracks the cab. The only excep-
tions are the HEMTT and M35A3, which
don't need the reinforcement kit.
