Abstract: A lock having a pin inserted into openings in the housing and the shaft to lock the shaft against movement relative to the housing. A lock guard is welded to the housing and a pin and ball receptacle is welded to the opposite side of the housing. A pin lock inserted through the lock guard, through the housing and the shaft into the pin and ball receptacle includes an outer pin containing a pair of ball bearings disposed within openings in the end of the outer pin. When inserted the pair of ball bearings are disposed adjacent to depressions in the inside surface of the pin and ball receptacle. A cylinder key lock is attached at the end opposite the key to a rotator which engages an inner pin. The inner pin has a large diameter section and a reduced diameter section at its end. When the large diameter section is in contact with the ball bearings, the ball bearings protrude through the outer pin and engage the depressions in the pin and ball receptacle to lock the outer pin to the pin and ball receptacle.
