Saved me from having to buy a new motor!
I'm replacing Harbor Freight's dust collection motor that has the 20mm shaft that's basically close to 3/4". Some of you know that those motors are only designed for 110V and it's not exactly 2HP like they advertise so replacing it with a 120/240V motor from Grizzly with the standard 5/8" which I didn't double check. I looked around on Amazon and sure enough, there's an adapter! It is indeed stainless steel checked with my magnet and is of quality. It slipped on the 5/8" shaft with very little play. I already bought some stainless cup point set screws and will drill into the impeller's side at 90 degree each to keep them held in place. There's plenty of length so I'll be cutting it nice and flush with my metal saw. The key for the adapter exposes out enough it shouldn't be an issue. For the price, you can't beat it! Otherwise, I'd have to shell out more money to get the right motor.

Fits 79 cc engine 5/8 shaft
This will not fit a 212 engine. this will fit 79 cc and smaller 5/8 shaft converts it to 3/4 for a bigger pully on a smaller engine

May be a little snug but better to be a little bit tight than a little loose
Worked perfectly would definitely purchase again
