We have our new motor installed. It works fine and with some very minimal mod we were able to get our Grizzly back up and running after burning out the previous Grizzly motor.

The Leeson motor is made as a Unisaw motor replacement. I had not heard or read of anyone doing this so thought I would pass the info along. It is more likely no one will ever have to replace their cabinet saw motor unless you buy older equipment like I do.

Oh yeah, the Grizzly has a good fence I stole off of an older 80s model PM66 and now it has a 4 hp Unisaw motor. This saw is getting better with age :)

As a side note, I have an active bid on an older model 24” Delta planer, hopefully I win the bid. I also bid on an older Rockwell 14” bandsaw, both bid with a local school district. The planer will be nice if we win it because we will then have a dedicated planer, now the Woodmaster shares duties.

I suppose no person has ever had a need to replace their grizzly motor on their g1023.

Our leeson motor has been working great this past week with the older Grizzly table saw. It is like a brand new table saw now :)

If anyone ever does need to replace their table saw motor on either their Grizzly cabinet saw or even on their Unisaw I can provide a good recommended motor source that has good prices on good motors.

I recently replaced my unisaw motor, got a Leeson 4hp motor on eBay for $450 delivered, I’m curious if you found a cheaper source?

Airspeed, I bought our motor from the same vendor who list on Ebay. I just ordered on the phone instead of going through ebay. I wanted to speak with a live person before buying the motor. I think I spent about the same amount, I think it was 392.00 plus shipping. It seems to be a good motor and worked out great for us. How is the motor working for your unisaw.

Thanks, I bought mine to replace a blown motor that was supposed to be new when I bought my unisaw, the guy lied to me, it was a Leeson 4hp but was not new, after it blew up I took a closer look and realized the guy I bought my saw from simply painted it. The new 4hp Leeson motor is far superior, the second I hit the starter the blade is at full speed and is as smooth as a baby’s bottom!

Thanks again!

Jerry,

Did you have to adapt the pulley from the old motor to the new? I thought the Grizzly 1023 motor had a different shaft size than a Unisaw motor.

Incidentally, I put a 3 HP Leeson on my Unisaw a couple years ago and it’s been running like a champ!

Bill, yeah the unisaw motor has a 3/4 shaft, the grizz motor had a 7/8 shaft. I did not want to attempt any rigging of the pulley so I bought a comparable puppy 3.5” diameter with 3/4 ID. I got the pulley for an extra 32.00 from same place I got the motor. Only draw back was my new pulley only takes 2 belts but we have not noticed any power loss as opposed to before when using 3 belts. All in all I have been happy and now feel like our grizzly has been upgraded.

One minor modification was required on the saw in order to allow the blade to drop below the table. The new motor has 2 start capacitors extruding from the motor body preventing the blade to drop lower than 1/2” above table.
