I purchased a used PM 66 a few years ago and want to replace the matched v belts. Saw was manufactured in 1987. The manual that came with the saw lists 23" belts (4L-230), but the belts I pulled off the saw are 22" (4L-220). I don't know if the 22 inch belt were the originals or if the previous owner swapped the original 23" for 22" that he had on hand. Should I use the belts spec'ed in the manual or replace what was on the saw? Is there enough adjustability in the motor mount to make a 1" difference immaterial?
Thanks,
Rob
