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.
