M818 alternator belt part number?

[HarryT]

My brand new XM818 has eaten both of its alternator belts! I took one to the local NAPA store and they couldn't cross reference the Goodyear part number.
Does anyone know the civilian part number or where I can order an Army V-belt?
Thanks,
Harry

Should be a 3/8x 36"matched pair.


MS51065-36-2 should be Goodyear, Dayco

5133178 is GM and Economy

9580 should be Gates, Carquest and NAPA but double check the length.

16857 is the Hyster number

9580 should be Gates, Carquest and NAPA but double check the length.

My NAPA store crossed ref'd the alternator belt to this number...25-7360. I believe the belts are 3/4" wide.

Thanks for the part numbers. The local NAPA store only had one belt (3/8"X36") in stock so I'm waiting until Wednesday for the second belt.
Looks like lots of work to install the belts.

As Chief said, belts should be a matched pair.
My M813A1 alternator belts are Dayco15355. They fit fine.

I ask for a matched set of belts. The parts man said they only come as singles now and with the computer controls each belt is the exact same size.

The ones I just got from Memphis are a matched pair. I don't know how important that really is.
