Q 1. What Caterpillar machines does the WAI 17100N fit?

A. This starter motor fits Caterpillar Ag. & Ind. machines across 44 confirmed applications, including the 540S, 600S, 670S, T100C, T120C, T125D, T30B and T30B/C — all from the 1982–2001 production span. Use the selection widget to match your specific model and engine variant, or search our cross-referenced catalogue by machine model. Every fitment shown is backed by our Fit Guarantee.

Q 2. Does this starter replace Denso 028000-8230?

A. Yes. The WAI 17100N replaces Denso OE numbers 028000-8230, 0280008230 and 2807019, along with cross-references from Bosch USA (SR9944X), Delco Remy (DRS0328), Remy (1109422), Caterpillar (1109422 and 3T5649), Hyster (3004017), Sando (60402230) and Yale (2200071-47 / 220007147) — 12 references in total. If you are working from an OE parts book, search our cross-referenced catalogue by OEM number to confirm your match.

Q 3. Does this replace the Bosch USA SR9944X or Delco Remy DRS0328?

A. Yes, the WAI 17100N is a direct cross-reference for both the Bosch USA SR9944X and the Delco Remy DRS0328, as well as a range of Denso, Remy, Caterpillar, Hyster, Sando and Yale numbers listed in the specification table. If you have another reference number not listed here, ask Simon to check it against the full catalogue.

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

A. The 17100N is a 12V, 1.4kW OSGR (Off-Set Gear Reduction) starter with clockwise rotation and a 10-tooth drive pinion, built to Denso design. It is supplied brand new — not remanufactured — so there is no core charge and no worn components to contend with.

Q 5. What does OSGR mean on a starter motor?

A. OSGR stands for Off-Set Gear Reduction. In this design the motor armature and the drive pinion sit on offset axes, with a reduction gear set between them. This allows a smaller, lighter motor to produce the torque needed to crank larger engines — the configuration Denso specified for the original Caterpillar fitment this unit replaces.

Q 6. Is this starter motor brand new or remanufactured?

A. It is brand new. The condition is confirmed as Brand New in the product specification, meaning you receive a starter built from new components with no core exchange required and no remanufactured wear parts.

Q 7. Can I ask questions about this product before ordering?

A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.

Q 8. 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.
