Just wondering what is meant when trying to buy the belt for a compressor they ask whether it has a "performance Axle" or not.
Steeper gears got a bigger clutch pulley, therefore a longer belt. Patrick http://www.v8buick.com/index.php?th...ginal-gm-fan-belt-part-numbers-needed.283475/
Smaller pulley is 5”, larger appears to be 5 5/8” or so. Is your car a Stage 1? Was it built with 3.42 rear gears as a separate option? Patrick
I will have to measure pulley. My car is not a stage 1. The build sheet should tell me if I got special gears?
If you have it, post a picture. Some on here (probably Duane) can decode your gears and probably your compressor. But that won’t tell what it has now; it could have been swapped in 50 years. Patrick
...per '71 Assy Manual page 6-5.2, all GSs got large pulley compressor (label part# 5910725), my (non-Stage) 455 has a 25. Skylarks got a 5910724. Don't know if true for other years...
Mine has the 725 serial number and the outside diameter of the pulley is 5 5/8” Funny that when I sent away for a replacement Frigidaire sticker I told them I wanted the original for my car and they sent a sticker with 5910597 What Buick’s got 597????
...can't rely on vendors. Here you go https://www.ebay.com/itm/DB0467-197...=item5b34be09e4:g:1l0AAOSwB-1Yxc4Y:rk:23:pf:0 Someone may chime in on 597...
