Q 1. What does the WAI 19913N replace, and which machines does it fit?

A. The WAI 19913N is cross-referenced to 9 OE references, including Denso 228000-2180, Denso 228000-2181, Denso 228000-6070, Case 235907A1 and TELEDYNE TM27M00516. It is listed for the Continental TM27 (1992–2005) — 1 confirmed application in the WAI catalogue. Use the selection widget to match your machine by model or OEM number, or search our cross-referenced catalogue by any of the references above. Every fitment shown is backed by our Fit Guarantee.

Q 2. Does this starter motor replace Denso 228000-2180 or 228000-2181?

A. Yes. The WAI 19913N carries 7 Denso references in total, including 228000-2180, 228000-2181 and 228000-6070 (plus their unformatted equivalents 2280002180, 2280002181 and 2280006070) and Denso 2807071. If you are looking up a Denso number not listed here, use our cross-referenced catalogue or ask Simon to check whether it falls within the full set of 9 references held for this part.

Q 3. Does it replace Case part number 235907A1?

A. Yes — Case 235907A1 is one of the 9 OE references listed for the WAI 19913N. If you are sourcing a starter motor against that Case number, this unit is the direct cross-reference. Confirm your engine variant using the selection widget or search by OEM number in our catalogue.

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

A. The 19913N runs on 12V and delivers 1.4kW of cranking power. It is a Denso-design OSGR unit with clockwise rotation and a 10-tooth pinion. It is supplied brand new — no core return or exchange is needed.

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

A. OSGR stands for Over-running Sprag-type Gear Reduction. This design uses an internal gear-reduction stage to deliver higher torque from a more compact motor, and an over-running clutch (sprag) to protect the armature from being back-driven once the engine fires. It is the original Denso design specified for the applications this unit covers.

Q 6. 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.

Q 7. 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.
