    How to size an unknown CVT belt for cross reference?

    I took on a project FL350 that is getting a 503 air cooled transplant. I have figured out that it came from a Polaris Escapade snowmobile (I think it was made in 1987). It has an MBL - Three Stars belt with some identifying numbers on it, but I cannot find any info on the belt, even on MBL's website. They also have not responded yet to an email.

    The numbers are in small text and repeat line after line, but one of the numbers increments each line:

    SP4440 Z4 22 091 MADE IN USA 377
    SP4440 Z4 22 092 MADE IN USA 377
    SP4440 Z4 22 093 MADE IN USA 377
    SP4440 Z4 22 094 MADE IN USA 377
    SP4440 Z4 22 095 MADE IN USA 377
    SP4440 Z4 22 096 MADE IN USA 377
    SP4440 Z4 22 097 MADE IN USA 377

    The width is about 1.25" (32mm) and the length on the outside is roughly 44 5/16" (1129mm). Does anyone know of a website where I can cross reference this, or at least tell me if the dimensions match the stock 350 belt?

    Thanks.

    I must have deleted all my drive belt link stuff, probably because the headaches it gave me during the 600 Pilot testing! I just searched and searched, and found a few different helpful articles and charts. What it came down to with me was taking the buggy to a big sled shop and trying a bunch of them. An online retailer with a generous return policy is an option.
    I race, therefore I am

    I when through this, just found as much info as I could I bought a belt on Amazon, it was too long, I was able to return it and from there I knew what I needed, next one worked fine.
    it sounds to be that that is not too far off from a stock pilot or oddy belt, you should check out the pilot oddy forum
