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.
