Abstract
This paper describes a new repair program for the Westinghouse 1463-B traction motor used on the BART cars. The program has produced an increase of rewound motor Mean Time Between Removals (MTBR) from approximately 2000 h at the end of 1979 to 131,823 h based on 653 rewound motors by the end of 1981. The program is based upon a new specification that defines each step in the repair process, requires full testing of repaired motors, and sets an MTBR of 20,000 h that must be achieved by the time the rewound motor population operates 100,000 h. As of January 1982 the motor population has reached over 1 million hours with 10 contractual failures.
