Problem
Some 1S5440 Dowels were made with a chamfer on the ends instead of a radius. These dowels are used in certain governor groups and automatic timing advance units. The chamfered dowels may damage the threads of the bolts in the governor flyweight retainer and in the automatic timing advance units.
