## Discrepancy

(CAN) DURING A 500 HR INSPECTION FOUND DISTRIBUTOR BLOCK BUSHING WORN. THIS CAUSED THE GEAR TO WOBBLE.  WHEN THE GEAR WOBBLED THE ELECTRODE MADE CONTACT WITH THE BLOCK TERMINALS.  THIS CAUSED THE GEAR TO STRIP AND ELECTRODE TO BREAK. BUSHING POSSIBLY DID NOT HAVE ENOUGH LUBRICATION. (TC NR20060307010)
