Hi, Leon

Thanks for the quick reply. I am familiar with the lever and how it releases tension on the skinnier v-belt (part #237, shown on P. 57 in the Grizzly manual, which I appreciate your sending me the link to!)€¦.but I am trying to replace the drive belt (#138b). That lever does not seem to release tension for that belt. I had thought maybe I could take off the v-belt and slip the drive belt behind and then just sort of rotate the shaft while sqeezing the drive belt onto its gear, but it just seems too tight.

Maybe Im just missing something€¦.any thoughts?

I would probably take the lazy way out and carefully loosen nut number
206 on page 2 of the Grizzly parts manual for the #203 idler pulley
shaft:

That should let the pulley flop around enough to work the belt on.
Other choice is the motor mounts but that would be harder to get lined
back up again or so I think. I had the motor loose on mine when it was
new to get the little rice paper belt to line up and fit. It wasn't
much fun...

FWIW I never run it so slow that I need that cogged belt. I just keep
it on the motor directly using the smallest pulley for 400 rpm
