HEMTT…
D
ue to safety concerns, the old HEMTT split rim wheels are no longer available.
You now have to order a new two-piece, bolt-together wheel.
Here’s what you’ll need:
Instructions for installing the new rims start on Page 12-32.1 of TM 9-2320-279-20-2.
Just because your HEMTT needs a new wheel doesn’t mean you should do a com-
plete swap-out.
Split rims are still OK to use until they become unserviceable.
The bolt-together rim
does
require a
tubeless tire, though. So Michelin XL
tubed tires must be replaced with Michelin
XZL or Goodyear AT2A tubeless tires
before installing a bolt-together rim.
Early-production non-wrecker HEMTTs
have three 0.62-in bosses on the rear axle
hubs. These bosses should be reworked by
DS to avoid interference when installing
the bolt-together rims. The procedure is on
Page 11-4.1 of TM 9-2320-279-34-2 (Jun
87 w/Ch 3).
