A Dewalt 4-1/2 inch hand grinder that normally uses 110-120 volts? Probably fried the armature windings.

Check the switch (Out of grinder), and see if it has continuity. (OHMS test with multimeter) Pretty rare thing, but perhaps the switch took the brunt of the overload. If this is the case replace the switch.

(After checking continuity on armature, and field windings, of course. If either one is bad, a new switch won't help)

Which Model Number is it, and perhaps I can find an exploded drawing for you.

I have a dewalt 28402 grinder. I have replaced the pinion but I don't know how to get the helical gear out of the case to replace it. Any thoughts? Thanks Chris


You can buy the pinion gear as a seperate part but not the ring gear. Dewalt only sells the ring gear as a part of the gear case assembly, PN 623586-00.
