This is usually preventable with good PM. But a recent issue created a dangerous
situation that PM
won’t
fx. What’s that? Glad you asked.
Some units have found defective M989A1 HEMAT wheel assemblies, NSN
2530-01-506-7324. These were assembled by an unapproved wheel source. This
contractor welded together the inner disk and outer rim oF the wheel, NSN 2530-01-
289-3963. And your guess is as good as ours as to how long these defective wheels
will last!
Reporting Is Important
IF you fnd a bad HEMAT wheel assembly, submit a product quality defciency
report (PQDR) that includes the PQDR Number, quantity and point oF contact at
your CONUS location.
If your unit is OCONUS, replace bad wheel assemblies with good on-hand assets.
Or you can buy new ones through the supply system. Also, submit a PQDR.
Questions? See TACOM SOUM 10-024 online For details:

Inspections Offer Protection
IF you haven’t already, do this right away:
•±
Perform a one-time inspection for HEMAT wheel assemblies received or installed
on or after 4 Dec 08. Inspect
before
you use your trailer again, or at the next weekly
preventive maintenance checks and services (PMCS), whichever comes frst.
This doesn’t apply iF the wheel assembly is stamped with “TITAN” on the rim or
has the “M±R 20076” CAGE Code stamped on the disk. Those wheel assemblies
are good-to-go.
Wheels without hand holes are also good. A hand hole is an opening in the disk
area of the wheel between the bolt holes and the rim.
•±
Remove bad wheel assemblies, but
do not
remove the tire from the wheel
assembly!
•±
Classify all trailers with suspect wheel assemblies as NMC until they are replaced.
•±
Check the part number that is stamped on the disk portion oF the wheel. Bad
wheel assemblies have part numbers WN13610, WN13589, or WN13458.
