water pump pulley

[infidel got me]

Does anyone know of a source to purchase a 5 groove waterpump pulley? I did google it and came up empty. Flea-bay has pretty chrome ones, but they are only 3 groove. I've heard that you can remove a alternator belt and use that groove. I would rather do it right and use the 5 groove. It is a 6.2 liter. Thanks for any help.

I have only seen 4 groove HMMWV pulleys. Are you sure 5 groove ones exist?

there is actually 2 part numbers and nsn's for it. One is a red dot and the other is the military supply version. Confused me (does not take much )when I was looking for mine. My thought is to do the pulley at the same time I do the 200 amp conversion and the a/c in the spring.

OK. I went and pulled one of mine and it only had 4 is why I asked.

the 5th groove is for adding a/c. Interesting that I "think" they use a double belt clutch on the compressor but only drive it with one belt.

infidel, buy two 3 groove pulleys, cut 2 grooves off of one, and have them TIG welded to the other 3 groove pulley. Just don't pull yourself out from under the car using the floor jack handle.

I found one of the 5 groove water pump pulleys here: https://www.hummerpartsguy.com/PULLEY-WATER-PUMP-V-BELT-H1_p_3728.html

I just bought it. My mechanic says that's the one. I'll try to remember to get back out here to update you guys after my red-dot AC is blowing cold air.

Did the pulley work? I thought that was for the civilian one. I'm looking for the same thing.

 

[infidel got me]

Yes, worked perfectly!!!

How did you tension the belt? Is there a tensioner for the V-belt?

The a/c compressor is the adjustment.. no v-belt tensioner

 

[Lazboytt]

I have a pancake V-belt compressor so I got the newer style mount for the pancake compressor but that does not have any adjustments on there

Idk, Should have a tensioner if the compressor is fixed

 

[Lazboytt]

I wonder if they make a tensioner for the V-belt or if I would have to pick up one for the other belt and switch to pulley on it
