My Delta Unisaw has been working fine for fifteen years. Now all of

anything else? Thanks.

Check the incoming voltage first.


It "might" be the centrifugal switch in the motor.
It "might" be the start/run capacitors.
It "might" be the motor bearing.

That is going to require a remove and take to the
shop for those issues unless you are very familiar
with electric motors.

I would vote for arbor bearing.(I been wrong many times)

The only real way to determine which is the problem
requires removing top and taking off belts.

If the blade spins with belts off, it is not the arbor bearing.

Start with start/run capacitors remove and replace,
if that doesn't fix it, time to remove the motor for
a trip to the shop.
