The area of contact from the crank to the piece 2, keyed clutch disk looks good. Appears to have some small rub on it, but no loss of materials.
The keyed clutch disk has very obvious wear and grooving where it has made contact with the coil/field housing.
The field and housing. The potting melted partially out, and pulled the coil out from the recess and has some rub on the windings. No wires are cut/broken, and still pulls proper amps. The housing itself shows wear along both inner and outer lips with some 'mushrooming' on the lips. It appears even across the entire housing lip, and there is no wearing other than the lip, so the field was not installed off 'level' with the engine mount.
