2 bench grinders to disassemble

[crice63]

My old Victor bench grinder has been needing new bearings and cannot be ignored. I started tearing it down to where I need to separate the housing so I can pull the spindle out. It does not want to come apart. The bearing looks like it is pressed tightly into the end housing. What should be the next step?

I have another grinder on a pedestal, a Baldor that I got at a garage sale that shudders on start up. With both stones off it still shudders, so I think the spindle might be bent. But since I was tearing down the one, I decided to go for the other and got to the same point. I'm obviously missing some knowledge here.

End bells need to be separated from the main body of the motor. For the baldor tap that raised shoulder on the end bells where the bolt goes thru and gradually work your way around the circumference of the motor. A flat head screwdriver might work.

On the Victor it looks like you'll need to separate where the seam is between the main body and end bells. An old screwdriver with a thin sharpened tip might work. Turn the grinder over. Sometimes there's already a slot that's a good starting point.

Once the end bells are loose you might need a pulley puller to completely remove the end bells.

Be careful because centrifical start assemblys and wiring are attached to one of the end bells and need to be detached before you can completely remove that end bell. The rotors usually come out the side of the motor without the centrifical start assembly.

Thanks.

The end bells are separated. The Baldor had no connections to either end--both bells came right off and I pulled the rotor out easy. I used a puller to get the bearings off. The Victor not so easy. I pulled the left end off but the right end doesn't want to give way. I don't see where it is attached. There's no access to anything behind the rotor. I tried hitting the end, but it shifted the spindle inside the rotor so I hit it on the other end and got it lined up again. But the bell is still attached (as it is in the photo).

I got the one bearing off of the Victor. Hopefully you can buy bearings by the specs of the motor because the super tiny stamps on the edge of the bearings are incomplete at best. The two Baldor bearings seems to have different numbers, and the Victor just says 15 at 12:00 and C at 6:00.
