Product Number: 18759N
The WAI 18759N is a brand-new 12V permanent-magnet direct-drive (PMDD) starter motor. It is manufactured by Mitsuba, designed as a direct replacement for Remy RS41234 and Yamaha original-equipment units including 4WV-81800-00-00, 4WV-81890-00-00, 5KM-81890-00-00, and further cross-referenced part numbers detailed below. It is built to restore reliable engine-starting performance in applications where these original units are fitted.
The PMDD design uses a permanent-magnet field rather than wound field coils, producing a compact, lightweight unit well suited to smaller-displacement engines. Rated at 12 volts with counter-clockwise (CCW) rotation, the 18759N is engineered to match the electrical and mechanical specification of the parts it replaces, making installation straightforward for a competent technician.
Supplied brand new — not remanufactured or reconditioned — the 18759N carries WAI's quality assurance as a like-for-like replacement. Cross-references span Remy and Yamaha original-equipment numbers, covering 9 verified references in total.
