Q 1. Does this starter motor replace Denso 228000-5210 or 228000-5211?

A. Yes. The WAI 17458N is a confirmed replacement for Denso OE numbers 228000-5210, 228000-5211, 2280005210 and 2280005211 — all four Denso references are cross-referenced to this part. It also replaces Bobcat OE number 6665654. If you are searching by one of these numbers, this is the correct unit. Use the vehicle selection widget or search our catalogue by OE number to confirm fitment, and every match is backed by our Fit Guarantee.

Q 2. Which Bobcat and Clark machines does this starter motor fit?

A. Confirmed applications include the Bobcat 751C (1995–1997) and Bobcat 873C (1995), and the Clark 653 and Clark 751 (both 1994–1995). Agco Spra-Coupe 3440, 3640, 4440 and 4640 models (1998–2003) and equivalent Melroe Spra-Coupe variants are also covered — 13 applications in total across the four makes. Use the selection widget or search by OE number to verify your exact model and year.

Q 3. What are the key specifications of the WAI 17458N?

A. It is a 12V, 2.7kW starter motor using the Denso OSGR (Over-running Spring and Gear Reduction) design. Rotation is clockwise (CW) and the pinion has 10 teeth. The unit is supplied brand new.

Q 4. What does OSGR mean on a starter motor?

A. OSGR stands for Over-running Spring and Gear Reduction. It is a Denso-developed starter design that uses a gear reduction stage to produce high cranking torque from a compact unit, with an over-running spring clutch to protect the pinion on engine start. The WAI 17458N replicates this design to match the original-equipment specification.

Q 5. Does this replace Bobcat part number 6665654?

A. Yes. Bobcat 6665654 is a confirmed OE cross-reference for the WAI 17458N, covering the Bobcat 751C and 873C models listed in the fitment data. Search by this number in our catalogue or use the selection widget to confirm your machine's variant.

Q 6. Is this part covered by your Fit Guarantee?

A. Yes. Every vehicle and OE cross-reference shown for this part is checked against manufacturer data and backed by our Fit Guarantee. If it is not right, our Fit Guarantee or hassle-free returns have you covered.

Q 7. How do I confirm this part fits my vehicle or machine?

A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.
