Compressor belt help

[ivbeenrokd]

I've noticed the belt for the compressor on my deuce is either the wrong belt or it's just not tight enough. I can't see any way to tighten it and it would appear the radiator may need to come out to replace it. I tried searching the manuals but wasn't able to find it. Any help would be appreciated.

Thanks

The pulley is a two-piece deal that tightens on itself in order to tighten the belt. You have to unlock the outer half of the pulley by removing the two bolts. Then it takes a special wrench. The -20 TM will certainly have the info. (yep--page 642 of TM9-2320-361-20)

Thank you for the info. My last truck had that wrench with it but I never had to use it and it went with the truck when I sold it. Where can I get one?

Do a search here. One of the members makes them. I don't remember his name. Its a good buy. Be sure to get both wrenches that he offers. The second one holds the compressor shaft, while you are tightening the outer half of the pulley.

There is also a drawing that you can download, trace and make your own. Being a welder, I thought I would go that route. After I made two, that didn't fit, I thought buying the pair was a real good deal.

That belt is not supposed to be tight. Just snug enough so the compressor does not slip. If you over tighten it you can damage the compressor.

Just my two cents worth

Thanks for the heads up.

Currently I would say its not even snug. I think right now it is likely slipping and causing premature wear.

The TM tells you exactly how tight it needs to be.

Holding straight edge (6) along drivebelt (5), use 6-inch rule to push in center of drivebelt (5).
Correct drivebelt tension is 0.75 in. (1.905 cm) with firm finger grip on 6-inch rule.

I did the same thing, luckily we have big wrenches at work ( I didnt know about the special wrench back then)...it was a little hard at first , I used the 1 13/16th on the back of the pulley (between it and the compressor), and a 2 7/8th or 2 15/16th on the front of the pulley to break it free from the rust, then channel locks after that.

I did mine by holding th eback with a large wrench then tightening it with a big cressent hammer. Did the trick for me.
