M978A2/A4 HEMTT: Bent Bracket Blocks Manual Control

Dear Editor,

Please let PS Magazine readers know that a support bracket underneath the M978A2/A4 HEMTT tankers can interfere with the manual control (MC) V1 emergency valve if the bracket gets bent.

Soldiers may not notice it at first if the MC cable isn’t properly adjusted. But the more the bracket bends, the more it binds the cable. Soon, the cable is damaged and the MC won’t work at all.

If HEMTT operators find a bent support bracket, they should tell their mechanic so it can be replaced. Then the mechanic will replace the bracket, NSN 5340-01-618-5711, and readjust the cable to prevent future problems.

Editor’s note: Mike, thanks for that great tip! We added an illustration that shows a bent bracket and the bracket readjusted.
A bent bracket will make the MC cable bend, so get bracket replaced and cable readjusted
