M1097A1 Belt Help

[m38inmaine]

I have been retired from the Army for many years and it's been a while since I have been around the HMMWV, just bought one at auction and while I'm waiting for the paperwork to clear I am trying to order the parts I need. As you can see from the picture all the belts are missing, the PS pump looks like it broke a bolt and slung the belts off. The alternator has 3 grooves and the rest 4 grooves. What is throwing me off is the TM shows a 3 belt set so that leaves 1 missing. From the pictures I see of other trucks it looks like the inner most belt is a single belt, for some reason I can't seem to find that belt in the parts TM.

Thanks

OK I found it in the parts TM, NSN 3030-01-256-3616. Odd they use a 3 belt matched set then a single belt that runs on 3 of the same 4 pulleys.

The 3 belts match because they all go around all of the pulleys and need to be the same length, ps belt only goes around the crank and water pump I think, and is shorter.
