Question about Black & Decker 7448 1/3 Sheet Orbital Finishing Sander
Hello, I have a model 7404 sander . ubit runs( motor runs?) when turned on but unit does not vibrate/orbit for sanding. I have taken nit apart and shaft seems in good shape and borttom(sanding area) plate with pologon seems intact .... Any ide what is wrong ... and how to fix?
I read elsewhere of someone using JB Weld to fill in the pentagonal hole in the bottom plate, after coating the armature of the motor with a light coating of oil to keep the JP Weld from sticking. Assemble, and set aside for the JB Weld to set up.

Wear inhibitor part number 86355 has broken on you. When this part brakes it brakes into tiny pieces which then leave the case so it hard to tell whats wrong. They don't make this part any more as the 7404 was discontinued in October 1975. I hoped this helped. I have the same problem.
