Q 1. What does the WAI 10705N replace — which original part numbers does it cross-reference?

A. The WAI 10705N cross-references 12 OE and aftermarket references in total. The highest-demand originals are Mitsubishi 32A66-02100 and 32A6602100. It also replaces Denso 428000-1660, Denso 4280001660, Denso 9742809166, Delco Remy DRS0983, Perkins 32A6602100, Perkins MP10237, AD Kuhner 254495, BTS Turbo S512270, Farcom 106918, and Sando 60403380. Match your existing part number against these references, or search our cross-referenced catalogue by OEM number to confirm fitment.

Q 2. Which machines does this starter motor fit?

A. Fitment data on file covers Caterpillar agricultural and industrial equipment — one application recorded for the 2006–2010 model range. Use the selection widget to match your specific Caterpillar make, model, and engine variant, or search by OEM number such as Mitsubishi 32A66-02100 or Perkins MP10237 to confirm your machine is covered. Every fitment shown is backed by our Fit Guarantee.

Q 3. Does this replace the Denso original — what are the Denso part numbers it covers?

A. Yes. The WAI 10705N is built to Denso OSGR specification and carries three Denso cross-references: 428000-1660, 4280001660, and 9742809166. If your machine's service documentation lists any of these numbers, the WAI 10705N is the confirmed replacement.

Q 4. What are the key specifications of this starter motor?

A. The WAI 10705N is a 12-volt, 2.7kW Denso OSGR (Off-Set Gear Reduction) starter motor with a 10-tooth drive pinion and clockwise rotation. It is supplied brand new — not reconditioned or exchange. Full specification details are in the table within the product listing.

Q 5. Will this starter fit a machine with a Perkins engine cross-referencing 32A6602100 or MP10237?

A. The WAI 10705N carries both Perkins 32A6602100 and Perkins MP10237 in its cross-reference data, confirming it as a direct replacement for those original-equipment numbers. Search by either Perkins reference in our catalogue to verify against your engine build, or ask Simon if you need further confirmation.

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.
