My machine is a 343-190 planer thicknesser. Big old capacitor screwed onto exterior of Motor. It has been ally can type but rotted out and can see the film inside . The writing seems to indicate 25uf 440v type. The motor is a 220v. Will one of these capacitors with plastic case from ebay do? Cap has a set screw on end and 2 fly leads with brown and blue on them. Somebody mentioned not using a polypropylene cap. I don't know what they meant.
