I have a grizzly G5979 wood lathe. Well, I did a lot of modifications to it, so it really isn’t a grizzly anymore. But the inner workings of the headstock are the same.

I have had this lathe for 8-9 years and plan to replace the spindle, bearings, and pulley. My question is, how to I get the bearings and spindle out of this thing? Is it pressed in?

Also, since I am at it, I want to replace the reeves drive pulley with a fixed, standard pulley. I removed the motor and added a 2 horse 220v and VFD a while back and don’t need the reeves for speed control anymore. And it makes a lot of noise. The spindle is a 1×8, but I am concerned that a 1” id pulley might not fit. This lathe has a “1 inch” tool rest post that is actually metric and so a 1” tool rest won’t fit in the banjo. Any thoughts on where I might find a 3-4” pulley that might work??

Any help is greatly appreciated.

You will probably be looking at custom machining for a pulley replacement. I have the same lathe (HF Version) I would expect them to be a press fit but that’s nothing that a bearing/gear puller can’t handle. I would measure the shaft carefully and see what the parts and such will come to because that lathe is only $250 to replace with new.

If Grizzly, doesn’t carry parts, HF might. It is a 34706.

Thanks for your reply. I can get the parts from gizzly. I have the part numbers ready. Like I mentioned, I have modified this lathe beyond recognition. I built a custom stand filled with sand. I raised the headstock to give me a 20” swing, and replaced the 1/2 horse motor with a 2 horse 220v with a vfd.

Thanks for your reply

you can assume the bearings and spindle is pressed in. Otherwise the bearing would float around. Take it to a local machine shop and they can press it apart and back togther. You can press it too with a dead blow hammer and flat block. But if you have never done it, be careful and keep it straight. Hope this helps.
