missing spacer can be the difference between a HMMWV alternator wiring
harness that works and one that’s got a short.
Eyeball the rear of the 60-amp alternator in your truck to see if the harness is
“trapped” under a spacer. If it is, you’re good to go.
If there’s no spacer, get your supply folks to order one with NSN 5365-01-
289-4434. It’s Item 10 in Fig 32 of
TM 9-2320-280-24P-1. With the spacer
in place, the harness can’t chafe against
the alternator body and eventually short
out.
Secure the spacer with a thin spacer
plate, NSN 5365-01-289-7852; washer,
NSN 5310-00-721-7809; screw, NSN
5305-00-984-6212; and washer, NSN
5310-01-234-9416. They’re Items 11-
14 in Fig 32.
hat would you give, mechanics, to
be able to tighten HMMWV alternator
belts to specification as easily as turn-
ing a wrench?
You say it’d be worth a lot? Well, all
you need is an alternator drive belt ad-
justment tool.
The tool holds the alternator and the
belts in place after you’ve adjusted the
tension. That leaves your hands free to tighten the alternator bolts.
But you can’t buy one; you have to make it.
For the plans to make the tool and instructions on how to use it on 60-, 100-,
200- and 400-amp alternators, get a copy of TB 43-0001-62-8 (Jan 99). Pages 9-
27 through 9-33 have the info.
