   Bill,

   Do you know if the motor starts and runs, or are there other problems that make you worried about the brushes and wiring?  What is the saw wired for now? 

   Contacting Delta is probably the place to start.

   The motor does run. When I purchased it - theguy ran 220V directly to the motor, bypassing the switch and wiring.

   How can I contact Delt tools parts ordering? Cant find the 800#

   Always start with the manufacturer for information. Call rather than e-mail. They usually respond in an hour or less if they can't answer right away. Early calls are better than mid-day peak busy time.

   1/2" brush length is getting down there. They are standard size brushes in a soft grade. With the covers removed, slide the tension spring off the brush and pull it out. Find the corrasponding brush at the other end of the wire and do the same. Next do the same for the other pair of brushes. Take note on the order they are removed.

   I don't recall the wire connections for 230 volt, I will check. The standard switch is a double pole so it should be fine with out rewiring, but don't assume.

   The 1HP motor is a repulsion induction type. Very heavy with tons of tourque. Delta states that a repulsion induction motor produces 2.25 times the torque of a modern capacitor start motor.

   I love the old "bullet end" Unisaw motors. I have nine of them in single and three phase. Installed one in a 14" band saw. You can resaw 12" maple all day long and it won't quit or stall.

   To answer an earlier question - my saw motor does run. When I purchased it. The guy connected 220 directly to the motor, by passing the internal wiring and switch.

   I can read a portion of the plate on the motor and it mentions rotating something to access the brushes. When iI remover the cover plates, I can see the brushes but I can't  reach in and work on them. Also - it looks like the wires to the brushes is soddered. Is that correct?

   Questions -

   How can I get the Model # for my saw. The plate only has the Rockwell serial #, I compared it to the Sawcenter website's list. My saw was manufactured about 1950. how do I get access.

   How do I rotate the brush assemble so that I can get to he brushes?

   To install new brushes, Are the wires from the brushes attached with screws or are they soddered?

   Thanks

   Bill DeBender
