I have had an 8" Ryobi (I know cheap ****...it was a gift) bench grinder I've had for almost a decade. The other day I turned it on and saw some magic smoke out the back. It started not really wanting to start in the correct direction and with a jump start in the correct direction, it didn't really want to spin up to full speed. After some brief dis-assembly, I see some obvious issues. I am guessing this is the "motor-start" capacitor... which is obviously toast.

The motor was still working but was getting quite warm trying to run without this guy. Should I try to pick up another Cap with the same specs, or just toss the damn thing. I need a grinder so I can grind my boogered tig rods back to shape:lol_hitti

Found one on Prime for similar price. Specs look the same except for 400V max.

As long as the capacitor voltage is the same or higher as the old one it will work.

Just make sure the cap will fit in the space. Not all caps of that voltage and Uf are the same dimensions.
