Product Number: 18418N
The WAI 18418N is a brand-new 12V 0.8kW Denso PLGR starter motor. It is supplied as a direct replacement for Kubota original-equipment references 6A100-31150 and 6A100-31151. It is designed to replace worn or failed starter motors on Kubota compact utility machines, including the B21TL and B21TLB (2001–2009), and cross-references eight OE and aftermarket part numbers across Kubota, Denso, and Remy.
Built to a PLGR (Permanent Magnet Gear Reduction) design, this starter delivers consistent cranking from a compact, lightweight unit well suited to the tight engine bays typical of Kubota machinery. The clockwise rotation and nine-tooth pinion are matched to the original Denso specification, ensuring correct engagement with the ring gear without modification.
With 12V operation and 0.8kW output power, the 18418N meets the original Denso performance specification. Being supplied as brand new means there is no core charge and no reconditioning uncertainty — the unit is ready to fit straight from the box.
