I just bought a used 36-670 delta table saw with stamped steel wings. The saw vibrates really bad. I just changed the belt and still no change. I cannot change over to 220 die to the wiring in my garage. Is there anything else I can try.

Sounds like your motor pulley is out of line with your arbor pulley. It’s a simple fix, just loosen the bolts of the motor holding it onto the support plate and bring it in line with the motor pulley, Use a straight edge for accuracy.

I would also check that all bolts are secure, including the bolts holding the table to the trunion

If it’s not this, check the arbor itself, it may be twisted or a bearing maybe worn. This is the least likely but the one job you least want to tackle if the arbour/bearing needs replacing Good luck.

The belt may also have a ‘set’ to it. This occurs when the machine is unused for a while but the belt is left ‘in tension’. A belt replacement could be in your future. I use a harbor freight link belt on my -441, and there is no vibration.

Motor bearings, arbor bearings, broken motor mounting bracket, pulley alignment, belt set, warped pulleys, warped blade… what else? That’s all I can think of.

To help isolate the source, take the belt off and run the motor, If the vibration persists, it’s the motor shaft, bearings, motor mount, or pulley. If the vibration stops, it’s likely the arbor, arbor pulley, or belt. Check the alignment of both pulleys too. It could also be the blade….have you tried running it without the blade?

Changing to 220v wouldn’t solve a vibration problem.

Thanks for all of your help. I bought a new blade and the sliced most of the vibrations. I think I still will buy a power twist link belt. I love this saw I can’t wait for the next project.
