Abstract
Abstract Starting motors operated on direct current have a brush armature combination to provide necessary rotation. Brush plate assemblies conventionally include a brush plate with a plurality of brush holders attached thereto and an elongated stud as an integral part of the plate, to convey D.C. power to the plate. During maintenance, the elongated stud may be damaged. Replacement studs may be removably secured to the brush plate, thereby salvaging the original assembly, except for the damaged stud. In addition, new brush plate assemblies can be made with removeable elongated stud members.
