« Part 3: Not so lucky with the age of the saw Part 4 of Delta Unisaw series Part 5: Motor update »

I finally got around to checking on getting new pulleys. The guy at the electric motor shop told me to have them balanced instead. So I went to a machine shop and had them balance the pulleys. When I got home, I tried the saw – no pulley and it worked fine. Put the pulley on the motor and vibrating badly again. At this point I was a little ticked that the balancing didn’t work. So I decided I’d take the motor off and take it and the pulley to the motor shop and get their opinion. I thought, no, try it one more time.

So I did and errrrrr. The motor will not run now. So I took it off and got it to the shop yesterday. They said just a starter of starting capacitor probably (Yeah I quessed right). They are going to keep the motor and run though it. New bearing and new capacitors. Should have it back next week and the Saga will continue.

If I had know how big of a pain in the “you know what” this Unisaw was going to be I’d a never bought it.

Oh who am I kidding. I would have still bought it. Just venting a little I guess. By the time I get done I’ll have close to $700 in it and it’ll be like new. I guess that is still pretty good really.

Pretty good I’d say. I paid almost twice as much and I got a killer deal!

Ditto Gary’s comments. This is one of the annoyances we get when buying tools. Things like this happen on new tools as well but the warranty that comes with them makes it easier to handle. If you can get it up and running for this price you have a bargain.

Keep us posted on how it is coming along.

Kevin before you fix itthink about replacing it if the cost is only a few hundred more. but 700 dollers is good, I think I paid 2300 for mine with a 54” fence. so your still doing good.

I know I’m a little late in the game here but I’ll post it anyway. I had a friend that bought a new Powermatic Contractors table saw a few years ago. He called me up one day shortly after purchaseing it complaining about the saw vibrateing and was wondering if I had any ideas as to what it could be. At the time the new thing for Contractors saws was machined pulleys and the link belt. Confident that this would fix his problem I went over to his shop to help him take the pulleys off his new saw. Well, that didn’t go so good, we couldn’t get the pulley off of the arbor and basically destroyered the pulley in the process. Now I felt really bad for messing up his new saw and now he had to load it up and take it back to the stores service dept. to get the pulley off and replaced. So while thinking about all this I asked him, did you ever read the owners manual ? Does it say anything in there about vibration ? He says, no I never looked at the manual at all, it’s still in the bag. I said, could you please get it ? I’d like to take a look at it. Well sure enough, there was trhe answer. Powermatic says in the manual that if there is any excessive vibration to check the locking knob for the tilt hand wheel. It must be locked. Just a hunch, but maybe this is the cause of your vibration problem Kevin. I thought maybe it would be worth mentioning. From now on when people ask me about a problem with a piece of equipment the first thing I ask them is, did you read the manual ?

Woodchuck you are right. You should check the manual first. Luckily I have screwed things up in the past by not checking, so this time I did check. I have gone through all the steps to narrow the problem down to the pulley which is most likely or possibly the motor.
