24V clockwise starter motor identified by Cummins part number 5287988. Exact-number parts records identify it as a Cummins starting motor, and published application records associate the number with ISB, ISD and B6.7 engine families. Five exact owned white-background views show the same starter, flange, pinion housing and terminal arrangement. Replacement catalogs disagree on 5.5 kW versus 7.5 kW output and do not establish one universal pinion configuration, so neither output nor tooth count is asserted as a verified specification. Confirm 5287988, the original nameplate, pinion, flange and engine serial number before ordering.
