M984E1 HEMTT ... wheel seal reminder.

Dear Editor,

We've come across a serious number of leaking wheel seals, NSN 5330-01-048-6240, on our fleet of M984E1 HEMTT wreckers.

After investigating, we discovered that the inner wear ring was being mistakenly installed on the wreckers' wheels. The note on Page 12-21 of TM 9-2320-279-20-2 (Apr 87 w/C4) specifically says the M984E1 does not take wear rings.

When installed, the ring damages the seal. The result is a Class III leak and damage to the brake shoes and other internal parts, not to mention a big mess on the ground.

Could you remind mechanics to leave the wear ring off when installing a new wheel seal on the M984E1?
