Hello all,

I have a Grizzly G0456 wood lathe. I know its not a top of the line model but I have enjoyed having it in my shop. I think the motor in it is starting to act up a bit. I have noticed an occasional hot electrical smell and just have the suspicion that it might be getting ready to crap out. This bothers me because this is the one part of the year that I can spend some time in the garage using it. I contacted Grizzly about ordering a spare motor for it and they said that it was back-ordered. OK… SO… I asked them if they could provide the basic motor specs to see if I could find a replacement locally. Grizzly responded with “Unfortunately, we cannot provide any information regarding the motor, as we do not have a motor in stock to measure and have no schematic drawings.”

First off, this shocks the me. I have worked in an industrial business for many years. I can’t imagine one of my manufacturers saying that they don’t have schematics for one of their products.

So, I was just hoping someone in the community might have had a similar problem and located the motor specs while repairing their machine. And yes, If my motor finally craps out for good then I will tear apart the headstock and remove my motor. I just don’t want to mess with doing that while it still runs.

Thanks for any help

I’m not familiar with that lathe, but from the parts list and description over at the Griz site, it appears to be a 220V brush type motor? How old is it and have you checked the brushes for excessive wear and possible replacement? If it were mine, I’d yank it, crack it open and give it a good rehab before shelling out the bucks for a new motor. Electric motors are pretty hard to kill, and usually don’t just ‘crap out’ unless they are poorly (or never) maintained or allowed to overheat (which is usually a result of lack of maintenance!). Might just need a good cleaning out and some new bearings/brushes to be back to good as new.

Cheers,
Brad

First question is can it be cleaned out with an air hose? it might have dust in the internal switches etc?

Just a thought!.

We replaced motor on a Jet lathe at school and the problem was the screws fell out of the inner part of the fixed half of the Reeves drive and it was pushed into the motor where it badly deformed the place where the setscrews were to go and eventually locked up the motor so it would not start. When replacing the motor with a new one we found that and tried the old motor and it ran great with that pulley removed.

Thanks for the advice. I had to really swallow my pride just to ask in the first place. I am dreading trying to tear down the head stock but apparently that’s what I need to do. I didn’t want to take the downtime but what do they say… An ounce of prevention is worth a pound of cure? I definitely don’t want to pay the cost of a new motor… OUCH!

The wifey says that I don’t have any other commitments this weekend. So, I hope to take some time and work on the tear-down.

Thanks,
Buzz

If anyone could help me out. I need some suggestions on how to safely remove the sanding disk from my lathe. I am afraid to use my pullers to remove it. It is made out of thin aluminum and I am afraid of totally distorting the edge by using the pullers to apply force. Any thoughts or tips would be greatly appreciated.

Judging from the parts diagram, it doesn’t look like it’s pressed on as there appears to be a screw in the middle holding it onto the shaft… so a puller shouldn’t be needed. I’d try prying from behind as close to the shaft/hub as possible, providing you can get in there. I’ve found that those ball-joint ‘pickle’ forks work great for stuff like that. A little penetrating oil and/or some heat might help as well. Other than that, hopefully someone who actually owns one of those lathes can chime in with better suggestions.

Cheers,
Brad

I finally got the motor out. I tried to be very gentle with the sanding disk. I had removed the screw earlier but couldn’t apply enough gentle hand force to remove the disk. I broke down and used my pullers. I applied just as much pressure as I dared and tried turning it quarter or eighth turns. Applied just a bit more force to the puller by hand. Then Bam, it popped off, bounced off my hand and landed on the floor. Darn… I laid it on the bench and don’t see any distortion. Not exactly how I planned it.

I took out the brushes and they measure 5/8” long. I thought, well since I have done all this work I might as well just put in new brushes. They have some life left but I don’t want to do this again for a while. I went to the Grizzly site to order new brushes. They are discontinued. Just my luck…
