If you need a 1 inch shorter belt the part number would be k080643 . if 2 inches shorter k080642 etc etc..

I was pleasantly suprised to learn of this logical numbering when I changed pulleys. Go Gates!

Close, but not quite. Think of the last digit as being tenths of an inch. If you want to change the length by a whole inch, you have to change the second to the last digit.

A K080635 is 64 1/4" according to Gates.
