Q 1. Which Denso part numbers does the WAI 17614N replace?

A. This starter motor cross-references 18 Denso OE numbers, including Denso 128000-5370, Denso 128000-5371, Denso 128000-5372, Denso 128000-5373, Denso 128000-5620, Denso 128000-5621, Denso 128000-5622, Denso 128000-5623 and Denso 128000-5625 — 26 OE references in total across Denso, Case and AD Kuhner. Search our cross-referenced catalogue by any of these numbers to confirm fitment, or ask Simon if you need further guidance.

Q 2. Which Case machines does this starter motor fit?

A. The WAI 17614N fits 25 Case applications, including the Case 3150 Patriot (2004–2009), Case 3185 Patriot (2004–2009), Case 5130 (1990–1991), Case 5140 (1990–1991), Case 5230 (1992–2001), Case 5240 (1992–2001), Case 5250 (1992–2001) and Case 6030 (1997–2007). Use the selection widget to match your specific model and engine variant, or search by Case OE numbers including 116928A1 and 116928A2. Fitment is backed by our Fit Guarantee.

Q 3. Does this replace the Case part numbers 116928A1 or 116928A2?

A. Yes. Case OE references 116928A1, 116928A2, 116928A23, 1987565C1, A186247 and A187615 are all confirmed cross-references for the WAI 17614N. If your machine carries any of these numbers on the original starter, this unit is the correct replacement. Check the selection widget or search by OE number to verify your exact application.

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

A. The WAI 17614N operates at 12V with a power output of 3.0kW. It uses an OSGR (Off-Set Gear Reduction) design, rotates clockwise (CW) and drives through a 10-tooth pinion. It is supplied brand new and ready to fit without modification.

Q 5. What does OSGR mean and why does it matter for fitment?

A. OSGR stands for Off-Set Gear Reduction. It describes the internal drive arrangement of the starter motor, where a reduction gear is offset from the armature axis to multiply torque. This design is specific to the original Denso unit fitted to these Case machines, so using an OSGR replacement such as the WAI 17614N ensures correct dimensional and electrical compatibility with the existing mounting and ring gear.

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.
