My Ridgid TS3650 is experiencing some shuttering/jerking when the motor shuts down. It hops a little on start up, but it’s much more noticeable on shut down. When it gets towards the end of shutting down it jumps a bit a makes a pretty audible ca-chunk, if a zero clearance insert is being used you can here the blade make a nice wang sound. If I take the belt off it seems to be fine. It still passes a nickel test though and otherwise runs and cuts fine. Arbor bearing, maybe?

Any advice?

Just to eliminate variables, have you tried a different blade? Check that the pulley alignment is good too. You could also consider a different belt before resorting to new bearings.

Tried different blades, happens with all of them. I should have added, the motor mount is bent, but I have the motor shimmed to make the pulleys coplaner and aligned.

IMO the problem is the motor mount.
