6" Jointer Noise

[Smiles79]

Just picked up this Shopmaster JO-400. It's pretty noisy when I turn it on, and it looks like there's some play in the shaft that holds the knives.

Is this just worn out bearings? Are they easy to replace? Where can I get replacements?

Possibly Grainger

Motion Industries


Amazon or E bay

Can’t help taking it apart, take pictures along the way & hope the bearings have numbers stamped on them.

Maybe a Google search might turn up on it?

Just my 1/2 cents worth

Does that sound like bad bearings to you?

Forget the sound, a bearing should not have the play you show in the 2nd vid.

Also could be a camera trick, but I swear that is spinning the wrong way

I can’t hear anything .

But that shaft play shouldn’t be that way- just a scientific wild guess- I’d say bearing .

If those knifes need sharpened - they can be a pain to place them back . At least mine was, you tubes can help on that.

Unmute it, both clips have sound

probably really worn bearings. "easy" is a relative term. it should be easy to do , if you have the necessary tools. might need pullers etc .
likely they are very common bearings, available online or at a bearing supply house.
if it was mine, I'd be digging into it to see what's up

Have you tried taking off the belt to make sure the sound is in the jointer, and not the motor?

 

[micromind]

Are they ball bearings or sleeve?

Also, as noted, remove the belt and see where the noise is coming from. It could be something as simple as a loose pulley.

If it's ball bearings, there should be no side play. If they're sleeve type, a small amount of side play is normal.

It looks like backward to me too, but yes, it could be an optical illusion.

Correct rotation is to have the cutter knives roll toward the front. Clockwise looking at the non-shaft end of the motor.

 

[The Cobbler]

I thought of the belt too, and it could be adding to the noise, but with that much play in the shaft almost guaranteed a bearing issue too

Thanks for all the replies! I did spin it with the belt unhooked, the motor is fine. I was pretty sure that the amount of movement I saw in the shaft meant bad bearings. I will try to get some new ones and swap them.
