Product Number: 5918N
The WAI 5918N is a brand-new 12V PMDD (Permanent Magnet Direct Drive) starter motor. It is engineered as a direct replacement for Honda original-equipment numbers including 31200-ZJ1-004, 31200-ZJ1A-0040, and 31200-ZJ4-003, as well as the Remy reference RS41060. With 12 OE cross-references in total, this unit serves as a precision aftermarket substitute across a broad range of Honda-engined compact plant machinery.
The 5918N is built to the United Technologies PMDD design — a compact, efficient architecture that eliminates the conventional wound field in favour of permanent magnets, delivering reliable cranking with reduced current draw. Running at 12V with counter-clockwise (CCW) rotation and a 10-tooth pinion, it is manufactured to OE specification and supplied in brand-new condition, ensuring fit and performance from first installation.
Fitment extends across compact plant and groundworks equipment: the Rammax FP2SP and Rammax SP2 Self-Propelled compaction machines, the Ditch Witch 1820 trencher (1995–2005), and the Terramite T5C backhoe loader (1991–2005). Four makes, four models, all confirmed applications.
