Q 1. Which Komatsu part numbers does this starter motor replace?

A. The WAI 19869N cross-references 11 OE part numbers in total. The Komatsu references on this part include KOMATSU 600-813-7110, KOMATSU 600-813-7111, and KOMATSU 600-813-7112 (also listed without hyphens as 6008137110, 6008137111, and 6008137112). If your existing unit carries one of these numbers, this WAI starter is the direct replacement. To confirm fit by machine model, use the selection widget or search our cross-referenced catalogue by OEM number — every fitment is backed by our Fit Guarantee.

Q 2. Does this replace any Nikko OE starter motor references?

A. Yes — the WAI 19869N also cross-references five Nikko original-equipment numbers including NIKKO 0-23000-7160, NIKKO 0-23000-7161, and NIKKO 0-23000-7162. The full set of 11 OE references (across both Komatsu and Nikko) is listed on this product page. Search our catalogue by any of these numbers or ask Simon if you need help confirming your unit.

Q 3. What are the key technical specs — voltage, rotation and tooth count?

A. The 19869N is a 24V starter motor with clockwise (CW) rotation and an 11-tooth pinion gear. It uses an OSGR (Off-Set Gear Reduction) design and is supplied brand new. These figures should be verified against your original unit's spec plate before fitting.

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

A. OSGR stands for Off-Set Gear Reduction. In this design, a reduction gear set is positioned offset from the main motor shaft, which allows a smaller, lighter motor to deliver higher cranking torque — a characteristic well-suited to the demanding start cycles of plant and agricultural machinery such as Komatsu equipment. The WAI 19869N replicates the original Nikko OSGR configuration.

Q 5. Can I ask questions about this starter motor before I order?

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

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.
