ATX UDP belt length?

[hawkeye18]

I have a 3-piece UDP set. I don't know where they came from, other than Ebay. The PS pump has large holes in it, as does the WP pulley.

I don't know what size belt to get for it. Mine is squeaking, and I can't read the numbers on it. Does anybody know the correct length?

Yes, I searched. Most of the relevant posts are, er, gone.

I have the FPS 2 piece, and it's an 837, but I'm using an 835. I know this doesn't help much.

I have a FPS UDP (crank and alt pulley) kit and I still use the stock belt.

Hey Bill. You mind posting the engineering numbers off those OEM pulleys ?


MTX

KOA ??? 3300 (power steering pump)

E9DU ???? (water pump)

FO?U M A2A (alternator pulley)


ATX

KOB ??? 3300 (power steering pump)

F3DU ???? (water pump)

FO?U M A2A (alternator pulley)


Who made the UDPs ?

Correct!
took them awhile ago, will have to dig em back out-I have bins of 'STUFF' somewhat sorted. LOL

Oh, the UDP's are what I was told, are the newer old ShoShop ones. They did a few runs. The PS & alt are larger than stock-but the WP is same dia-just alum! thats OK as cooling is important!

The OEM engineering number on the alternator pulleys, will be located on the outer face of the pulley where the nut (24mm) clamps the pulley to the alternator shaft.

The SHOShop balancer and alternator pulleys look like they're chrome-plated steel, versus polished aluminum - are they ?

all 3 are alum. I had to get new longer bolts for WP pulley as the alum was thicker than the stock steel one. used some SS button allen head s I had. I did not have time to polish up the PS pulley as much as the others=time crunch! she was in the mid of a full frt 60K when Chris called me & wanted her there. then on a test run the night before, after we got it all together, I found a rear break hanging up. Had to replace a slider pin,boot,rotor & pad & free up the hose crimped in that brkt.

This is my 3.2 setup with ASP UDPs And I have a Gates K060735 on it which is I think a 74" belt. Notice the A/C is gone too. I hope this helps someone.
