Product Number: 19909N
The WAI 19909N is a brand-new 12V 1.4kW starter motor. It is built to the Denso OSGR (Offset Gear Reduction) design specification. It replaces Denso original-equipment references 228000-3930 and 228000-3931, as well as Toyota OE numbers including 28100-32850-71, 28100-32850RF, 281003285071 and 2810032850RF — making it a direct, cross-referenced replacement for buyers sourcing against either the Denso or Toyota part numbers.
The OSGR design locates the reduction gear unit offset from the armature centreline, which allows a compact and lightweight assembly without compromising cranking torque. At 1.4kW output on a 12V system, the unit delivers the starting power required by the applications it is specified for. Clockwise rotation and a 10-tooth pinion are confirmed in the manufacturer specification, so the engagement geometry and direction match the original.
Supplied brand new rather than remanufactured, this starter motor is manufactured to Denso specification under the WAI product range — ensuring the internal components, brushgear and solenoid meet the same build standard as the original-equipment part it replaces.

A. The WAI 19909N is a direct cross-referenced replacement for the following OE numbers: Denso 228000-3930 and Denso 228000-3931, plus Toyota 28100-32850-71, Toyota 28100-32850RF, Toyota 281003285071 and Toyota 2810032850RF — 6 references in total. If you are sourcing against any of these numbers, this is the corresponding replacement. To confirm suitability for your specific machine or vehicle, search our cross-referenced catalogue by OEM number or ask Simon.
A. OSGR stands for Offset Gear Reduction. In this design, a planetary or offset reduction gear set sits between the motor armature and the drive pinion, allowing the motor to spin at higher efficiency while delivering the required cranking torque through a smaller, lighter housing. The WAI 19909N uses OSGR design to match the Denso original-equipment specification exactly, ensuring correct fit and engagement with the ring gear.
A. The WAI 19909N is supplied brand new — not remanufactured or reconditioned. It is built to Denso design specification under the WAI product range.
A. Voltage: 12V. Power output: 1.4kW. Rotation: clockwise (CW). Drive pinion teeth: 10. Design: OSGR (Offset Gear Reduction). These figures match the Denso original-equipment specification for the cross-referenced part numbers listed above.
