My R4512 recently developed a nasty motor sound. In order to diagnose/fix it I had to disassemble the entire saw. So I’d like some advice on what I should do cleaning and tune up wise when reassembling seeing as how I don’t want to take this thing apart again anytime soon.

The big one to me is lubrication. What should I lubricate and with what? Should I clean off all of the factory grease that is covered in dust? Here is a good example of that.

And it’s mate.

When I reassemble should I use lock tite on set screws and the like? What kind? Does it matter?

Should I replace the nylon threaded nut holding the motor on with a fresh one? I normally wouldn’t ask and would just use it, but one nut (no matter how big) holding the motor for the table saw on makes me wonder if using a new one would be advised.

Would coating the inside of the saw and dust chute with paste wax help with dust collection? I’m using a shop vac with a dust deputy. And after opening this thing considering never cutting MDF again…

Looks like I forgot to take a picture of the fan on the motor that’s giving me grief, but here is a video. I’ve not been able to budge the bushing holding the fan on at all. I need to in order to keep the fan on and prevent that rattle. Any suggestions?
