Product Number: 18490N
The WAI 18490N is a brand-new 12V 2.0kW starter motor. It is built to Hitachi OSGR specification, designed to replace original-equipment units on Thermo King and Carrier Transicold refrigeration units. It cross-references directly to Hitachi S13-207A, S13-207C and S13207 among 28 verified OE references, making it the go-to replacement for fleet operators and independent workshops servicing transport refrigeration equipment.
Constructed to OSGR (Off-Set Gear Reduction) design principles, the 18490N delivers its 2.0kW of cranking power through a 9-tooth pinion with clockwise rotation, matching the geometry and engagement characteristics of the original Hitachi unit. The OSGR layout positions the reduction gear offset from the armature axis, which keeps the motor compact while sustaining reliable engagement torque — a particularly important attribute on refrigeration engines that may sit at low ambient temperatures between duty cycles.
The 18490N covers 21 fitment applications across Thermo King and Carrier Transicold, including Thermo King Magnum, SB-200, SB-210, SB-300, SB-310, SB-II SR and SB-III SR units from the late 1990s through to the late 2000s, plus Carrier Transicold various models. It also carries Yanmar OE references (126486-77010, 126486-77011 and 129486-77011), Bosch USA SR5062X and Remy 93591, reflecting the breadth of engines fitted across these platforms.
