A. The WAI 18284N cross-references 12 Hitachi original-equipment numbers, including Hitachi S24-03A, Hitachi S24-03B, Hitachi S24-03C, Hitachi S24-13, Hitachi S25-120, and Hitachi S25-120A, among others. In total there are 29 OE cross-references for this part spanning multiple brands. Search the cross-referenced catalogue by any of these numbers to confirm fit, or use the selection widget — every fitment shown is backed by our Fit Guarantee.

Q 2. Does this starter replace the Delco Remy DRS3219?

A. Yes — Delco Remy DRS3219 is one of the 29 OE cross-references listed for the WAI 18284N. If your machine currently carries a Delco Remy DRS3219 starter, this WAI unit is the cross-referenced replacement. Verify against your machine's original part number in our catalogue or ask Simon if you need further confirmation.

Q 3. What Isuzu equipment does this starter motor fit?

A. Fitment data covers Isuzu miscellaneous industrial equipment from 1979 to 1989, representing one recorded application. Isuzu OE references cross-referenced to this part include Isuzu 5811001280, Isuzu 5811001281, Isuzu 5811001282, Isuzu 8942549221, Isuzu 8943205310, and Isuzu 8943334380. Use the selection widget or search by your Isuzu OE number to confirm the exact match for your engine — every fitment shown is backed by our Fit Guarantee.

Q 4. What are the key specifications of the WAI 18284N?

A. This is a brand-new 24V, 3.5kW starter motor built to Hitachi OSGR (Off-Set Gear Reduction) design. It operates with clockwise rotation and drives through a 9-tooth pinion. Full specification details are in the table on this listing.

Q 5. What does OSGR mean on a starter motor?

A. OSGR stands for Off-Set Gear Reduction. In this design, the reduction gear is positioned off-centre relative to the armature, which allows the starter to produce high cranking torque from a more compact and lighter assembly compared with a direct-drive unit — a useful characteristic in space-constrained plant and industrial engine bays.

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.
