It's only available as the motor assembly at $200. However, the dealer that sold me the saw did get Ryobi to send just the part, but it was the right part number but a similar but different part. It appears the part for this vintage is no longer available, and no guarantees the one on the motor assembly is the right part, either.

I strongly suggest pulling the whole mess out of the saw and setting it up on a drill press to do the new tap drill. Chances of success the first time are greatly improved.Comment

I went through this several years ago. I would go with the helicoil first or something similar. helicoil does trade on its name but the patents have long since expired and there are copycats that work. Reason is that if it fails, or you screw it up (it's possible trust me), there is still one more shot with at keensert (or equivalent). Admittedly all this gets expensive and increasingly frustrating

Now, retract the setup bit and install the working bit in the chuck. When you drill the hole, it will be perfect.
Or just give it to a machinist or engineering tech and let them do it.Comment

I've used heli-coils, Time-serts, and E-Z locks quite a bit. The problem with an E-Z lock is for a 9/16-12 insert you have to drill and tap a 3/4-10 hole. Is there enough material in the boss for a 3/4" hole? The other problem is a 3/4-10 tap is going to cost $40+ and another 10 for the insert pack vs $30 for an Heli-coil full kit.Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas EdisonComment

Thanks, everyone, for your comments and suggestions. I think I will go with the heli-coil, for the reasons mentioned. I had envisioned using a dial indicator to square and center the drill, but the drill method solution will be so much easier.
Thanks again for all your help!!--------------------------------------------------
