To confirm your specific model and engine variant, use the selection widget to match by make and model, or search our cross-referenced catalogue by OEM part number. Every fitment shown is backed by our Fit Guarantee.

Q 2. Does this replace Kubota part number 6C140-59210 or 6C04059212?

A. Yes. The WAI 18396N cross-references directly to Kubota 6C04059212, 6C140-59210, 6C140-59211 and 6C140-59212 among others. In total, 17 OE and aftermarket references are on this part across Mitsubishi, Kubota, DRI and Sando. If you are matching by a different number, search our catalogue by OEM reference or ask Simon to confirm.

Q 3. Which Mitsubishi OE starter numbers does the 18396N replace?

A. The WAI 18396N replaces Mitsubishi OE numbers including M000T71981, M000T90281, M000T90282 and M000T90284, as well as the short-form equivalents M0T71981, M0T90281, M0T90282 and M0T90284 — 8 Mitsubishi references in total across the 17 listed for this part.

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

A. The 18396N is a 12V, 0.9kW permanent-magnet gear-reduction (PMGR) starter motor with clockwise rotation and an 8-tooth pinion, supplied brand new. It is built to the original Mitsubishi specification, so it is a direct replacement with no modification needed.

Q 5. What is PMGR design and why does it matter for my Kubota?

A. PMGR stands for permanent-magnet gear reduction. The gear-reduction mechanism allows the motor to run at a higher internal speed, generating more torque before the pinion engages the ring gear. This makes it particularly efficient on the compact diesel engines fitted to Kubota B-series tractors, delivering reliable cold-start cranking from a compact, lightweight unit.

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.

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.
