Hmmm, I went out and bought a bypass pulley nad now I see they make belt w/o ac

Buy Drive-Rite V-Ribbed Belt 870K6 at Advance Auto Parts

 

Does anyone know if its possible to just run the belt above to bypass the compressor?

 

I found the diagram below for with and without AC. Without AC still has a pulley where the AC compressor is it just seems lower.

 

Have a 2000 blazer and ac was locked up and ran great with a shorter belt till tensioner pulley blew now on 4th belt in less than a week can figure out why

 

I would expect the a/c clutch that never gets engaged to play and idler wheel role.

 

Without the AC clutch or bypass pulley / or a idler pulley in non AC units it throws the belt angle off and in by doing so increases tension on the belt from the belt Tensioner

 

I can tell you what happens when a meth head gets creative and just throws a belt on without the bypass pulley. The power steering pump takes the abuse and the bearing wears then the belt starts to be thrown off as soon as the truck starts.

It can be done for a short time but term it's a really bad idea. The real trick is getting the right bolt and the washer that holds the pulley and bearing in position.

I got one at pick n pull for a couple of bucks which included the pulley as the idler pulley would work also.

 

For me, permanently disengaged a/c clutch is equal to an idler wheel. Why are You reinventing the wheel here?
