Abstract: A method and apparatus are provided for replacing a commutator on a starter armature in which radially extending, circumferentially spaced commutator contact wires are interspaced between and soldered to mating contact wires on the armature. A heated platen includes at least one receiving hole through which the commutator is placed so that the soldered connection between the commutator and armature contact wires rests against the platen to thereby melt and remove the solder. The commutator is secured in a chuck while the armature is driven away from the stationary commutator. Thereafter, a novel tool spreads the rotor contact wires radially outwardly which permits a subsequent and new commutator to be positioned over the armature shaft so that the new commutator contact wires are interspaced between the armature contact wires. The contact wires between the new commutator and the armature are then soldered together by dipping the assembly into a solder pot heated by the platen.

Abstract: A method and apparatus are provided for attaching a first member having a predetermined cross-sectional shape to a thin walled second member at a predetermined attachment position. The second member is supported on one side around the outer periphery of an area substantially corresponding to the shape of the first member at the attachment position on the second member. A drive means then engages and drives the first member through the other side of the second member at the attachment position whereby the first member punches a plug corresponding to the shape of the first member from the second member. The first member thus forms a hole in the second member in which the first member is frictionally engaged.
