I recently picked up a Powermatic 62 off craigslist for $250. It’s a very cool saw, and, as you might imagine, I have developed feelings for it. However, all relationships come with some baggage. We have issues. The first thing I noticed was that it shakes like a washing machine when I turn it on. (Is it something I said?) Upon closer inspection, I could see that the blade has some side to side wobble as it turns. (It’s not the blade itself.) I figure the problem is either a bend in the arbor shaft itself or worn out arbor bearings. Wondering if anyone has any experience with these machines or a similar problem.

I have discovered that the bearings are a common model, so will be easy and cheap to replace. I have removed the arbor and it is not obviously bent, so I am hopeful the bearings are the problem. Any advice for things to watch out for when replacing the bearings? (e.g. Is there something I need to do to make sure they are straight, or will the housing take care of this for me?)

Also, supposing the bearings don’t do it. I guess my next step would be replacing the arbor itself? I hope not. I have read that the 62 shares some parts with the 66, which are readily available. Anybody know if the arbor shaft is one of these? They look similar in manuals. The part is around 175 bucks, so I’d rather avoid going that route if I can. I’m going to replace the belt with an original model, just to cover my bases. Any other thoughts?

Check the arbor flange. Take the blade off and using a
pencil, icepick or similar instrument, contact the flange
lightly and rotate the belt. You’ll be able to feel if
the flange is out of flat. You’ll be resting your hand
holding the instrument in such a way that the your
hand won’t move.

If the flange is out of flat look at for
the article on flange facing with an oil stone.

You certainly may be right about the bearings but
don’t jump to that conclusion just yet.

A picture would be nice. They look like pretty nice heavy contractor saws. The guys on could tell you about interchangeable parts. Hopefully for a few more bucks for a belt and bearings, you’ll have a nice user.

I am not familiar with Powermatic. However, when you get your wobble solved, change your belts to power twist belts. It made an enormous difference on my saw and most of the jocks on this site agree that they are a worthwhile changeover.

Great! Thanks for the info, guys. I’m already committed to the bearing and belt change, so I will check the arbor flange after that. Then I’ll look into the power twists if I feel the need to take it to the next level. What are supposed to be the advantages of those belts?

Never mind that question on the power twist. The search function answered it just fine. I’m going to check out the Harbor Freight version. Thanks guys.

mrbpfister, power twist belts are a fine replacement because the reduce the a out of vibration of a belt powered tool as they do not allow harmonics to build up.

Vibration in a power tool, although probably not dangerous, are a nuisance and can result in fatigue in both parts of the tool and the operator.
