I rescued a Dewalt radial arm saw from the junk pile. It's in very nice shape considering, but needs some TLC. When I plug the unit in, I have to hand spin the blade to get the motor to start. This suggests that the motor start capacitor is shot. Removing same from the unit, the cap fell apart in my hands.
The cap is marked 86 - 103 mf, 110 VAC. Looking inside the broken cap, there is a 1 watt resistor across the terminals too. Finally, there is a relay mounted near the cap (which I assume, switches out the cap when the motor starts).
Looking around the web, I found this unit.http://www.epoolshop.com/runcapacitor88-108mfd125v1-7/16x2-3/4.aspx
It has a range of 88 - 108 mf at 125 volts.
How close in value does the replacement have to be? Will this work? What are the important specs that I need to consider?
Second, can I assume that the cut out relay is 110 VAC, and can I replace it with a generic equivalent, or might this item be something special?
Called Dewalt, but they need a model off the saw, and that model plate is long gone.
