Ridgid R4511 Arbor Washer Issues

Hi, I’ve searched and seen this topic posted to death! :) However, I’m having an issue w/ my arbor washer. First of all, my saw is not covered under the recall. The production code is CD0850. I’ve been taking blades on and off experimenting with cross cutting, ripping, and cutting dadoes. Evidently, I’ve overtightened the arbor nut and distored the shape of the washer. It’s very difficult to remove and I’m afraid that I’m going to damage the threads on the arbor. I’ve tried to file and hone the arbor washer, but am not getting any improved results.

I have a part number but, of course, can’t find the part online. I waited too late to call Ridgid customer service and will have to wait until tomorrow. If they can provide the part, I believe I’ll order 4 or 5 to have some spares.

I’ve read that I may have over torqued the arbor nut but I cannot find any reference to what torque specs I should use (I’ve searched Ridgid forums and the provided owner’s manual).

Can anyone provide some insight into the torque specs or where I could find the arbor washer, or an appropriate substitute?

By the way, thanks very much for the myriad welcome notes I’ve gotten since joining the site last week.

Jeff
