Q 1. What Hitachi original-equipment numbers does the WAI 16740N replace?

A. The 16740N crosses to 15 Hitachi references, including Hitachi S13-121, Hitachi S13-321, Hitachi S13-62, Hitachi S13-62A, Hitachi S13-62B, Hitachi S13-62C, Hitachi S13-63, and further S13-series variants. In total this part carries 46 OE cross-references spanning Hitachi, Bosch, Delco Remy, Valeo, and Magneti Marelli. Use the selection widget or search our cross-referenced catalogue by OEM number to confirm your application, or ask Simon.

Q 2. Does this starter motor replace Bosch or Delco Remy units?

A. Yes. The 16740N replaces four Bosch Exchange references — including 0986014070, 0986014071, and 0986601407 — as well as Delco Remy DRS4071, Remy 16740, Valeo 458529, Valeo VS422, and Magneti Marelli 944280529060, among others across its 46 total cross-references. If you have the part number from your existing unit, search our catalogue to verify the match.

Q 3. Will this starter motor fit my Isuzu machine?

A. The WAI 16740N fits Isuzu Misc. Industrial Equipment manufactured between 1982 and 1986 — one confirmed application in our catalogue. To verify fit for your specific engine variant, use the selection widget with your make, model, and engine details, or search by your existing OE part number. Fitment is backed by our Fit Guarantee.

Q 4. What are the key specifications of the WAI 16740N?

A. It is a brand-new 12V, 2.0kW starter motor built to Hitachi OSGR (Off-Set Gear Reduction) design. It runs clockwise rotation and uses a 9-tooth drive pinion. Being brand new, there is no exchange core to return.

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

A. OSGR stands for Off-Set Gear Reduction. In this design the motor and drive gear are offset, with a reduction gear between them, allowing a more compact and lighter unit to produce higher torque than a conventional direct-drive starter. When replacing an OSGR unit it is important to match this design — fitting a conventional direct-drive starter in its place will not be a direct swap. The 16740N is confirmed as OSGR, matching the original Hitachi specification.

Q 6. Is this a new part or a remanufactured exchange unit?

A. The WAI 16740N is supplied brand new. It is not a reconditioned or exchange unit, so there is no core surcharge and no old unit to return.

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.

Q 8. 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.
