Q 1. Does this starter motor replace Mitsubishi part number 37566-00500 or 3756600500?

A. Yes. The WAI 19951N is directly cross-referenced against Mitsubishi OE numbers 37566-00500 and 3756600500, making it a confirmed like-for-like replacement for those original-equipment units. To confirm it is the right match for your specific machine, search our cross-referenced catalogue by OEM number or ask Simon.

Q 2. Which Nikko part numbers does the WAI 19951N replace?

A. This starter cross-references to four Nikko original-equipment numbers: 0-23000-7740, 0-23000-7741, 0-23000-7742 and 02-23-4007. There are 6 OE references in total across Mitsubishi and Nikko. If your existing unit carries one of these numbers, the WAI 19951N is the confirmed replacement. Use the selection widget or search our catalogue by OEM number to verify fit for your application, or ask Simon.

Q 3. What are the key electrical and mechanical specs on this starter?

A. The WAI 19951N operates on a 24-volt system, uses an OSGR (Off-Set Gear Reduction) design, rotates clockwise (CW) and engages the ring gear via an 11-tooth pinion. It is supplied brand new — no rebuilt or reconditioned units.

Q 4. What does OSGR mean and why does it matter?

A. OSGR stands for Off-Set Gear Reduction. The reduction gear set is positioned off-axis from the main motor body, which increases cranking torque without proportionally increasing the motor's physical size. This makes it a practical choice for the high-compression engines and demanding duty cycles common in 24-volt plant and agricultural machinery.

Q 5. 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 6. 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.
