My father in law has an old Rockwell Model 9 contractors table saw that he has lost the capacitor to the motor. I am trying to find out which capacitor is needed. I have checked with various electrical houses and they tell me I need to get the MFE rating on the capacitor. The motor is a model 34-607, 1 HP, 115 v, 3450 rpm, motor that has a Delta # of 62-145 on the plate. I would appreciate any information provided on the capacitor replacement or a suitable motor replacement for the saw.
Again thanks so much. Jackson5

Can’t help you with the Cap. rating, but any 1 hp, 115v, 3450 rpm motor that will mount in, that has the same rotation will work. Last motor I bought for my saw was an on sale Harbor Freight.

Re: the cap, it doesn’t have to be an exact match for capacitance….I’d guess somewhere in the 30 to 100 mfd range would work fine. It has to be able to handle the electrical input, and obviously they need to be able to physically fit inside the cans. You can always check another 1hp motor as an example.

Most motors of this size have two capacitors. One for starting and another for running. You might check with a motor manufacturer’s website and look for a similar motor to see what size capacitors they use. You can also check the WD Grainer web site for the same information.
