Absolutely, there's not nearly enough adjustment available to make up for the pulley diameter difference.

You'll have to figure out the new length on your own.
I usually take an old belt and cut it to try to make up one that's close, then go to the parts store and get some help. It might take a couple of tries to find the right belt that will adjust properly. |
