What was found
THE (2) BEARINGS THAT SUPPORT THE DISTRIBUTOR ROTOR GEAR (LARGE GEAR) WERE FOUND TO BE WORN OUT. A CONSIDERABLE AMOUNT OF BEARING MATERIAL WAS DEPOSITED THROUGHOUT THE DISTRIBUTOR HSG. ALSO, BECAUSE THE GEAR WAS ALLOWED TO MOVE WITHIN THE WORN BRG, OTHER PLASTIC MATERIAL WAS GROUND OFF FROM THE DIST BLOCK. AS A RESULT OF THE CONTAMINATION THE POINTS CAM WAS FOUND TO BE WORN DOWN AS WELL. THIS DAMAGE WAS DISCOVERED DURING THE SECOND 500 HR IMPULSE COUPLING AND MAG INSPECTION. THE PART WAS STILL FUNCTIONING WHEN THE PROBLEM WAS FOUND.
