Dorsai Posted July 19, 2019 Author Share Posted July 19, 2019 Matched pairs are important for applications like this. I'd swap belts long before I tear into a clutch or compressor. When I go back to NAPA to return my starter core, I'll ask that nice counter girl if she's got a matched pair. What's the worst that can happen? You could get slapped? For asking for belts? Wait...what are you thinking of? (OK, I'll stop now.) Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted July 19, 2019 Share Posted July 19, 2019 Maybe one has stretched to the point of chirping? "ONE" can't chirp. Both sheaves are tied together on both sides. There is no way for one of a pair of belts to lose or gain ground on the other. Link to comment Share on other sites More sharing options...

My A/C compressor on July 9: And on July 19: I am absolutely baffled as to why and how that belt disappeared. I distinctly recall checking all my belts when I was installing the new belt for the air pump, and it was (superficially at least) in excellent condition at that time.

Working at a parts store she probably has to deal with guys being jerks all the time - I wouldn’t be surprised if she kept a tire iron under the counter...

You need to ask her if she'll step outside and whack your starter.***with that tire iron*** Link to comment Share on other sites More sharing options...

Funny how they stayed on for years but as soon as you 'fixed' that bracket.... foof! they're gone. Link to comment Share on other sites More sharing options...
Gary Lewis Posted July 19, 2019 Share Posted July 19, 2019 Please video that. I gotta see it. https://www.canstockphoto.com/violence-at-office-5830229.html David - That's about what I expect. Matthew - You've just proven Jim wrong. It is entirely possible for two belts on the same pulleys to have different rotational speeds. One of them just has to break.

Rembrant Posted July 20, 2019 Share Posted July 20, 2019 Belts can be purchased in factory matched pairs, for applications as this. I guess the tolerances are more closely matched. If one purchases the same part number in separate packages, one may be slightly longer. We've requested matched V-belt sets for industrial applications before. It does matter. They're cut like slices of bread from a loaf, and every loaf is going to be a little bit different. I don't believe I've ever had a vehicle with a double v-belt set up. Of all the vehicles I had that were old enough to have V-belts, they only ever had an alternator and a power steering pump that were belt driven.
