Product Number: 18343N
The WAI 18343N is a brand-new 12V 4.0kW starter motor. It is built to Denso OSGR specification, replacing original-equipment units from Denso, Remy, Iskra, Mahle, and Letrika across a wide range of Case combine harvesters. If you are cross-referencing by OE number — including Denso 228000-5620, Remy 10461645, Iskra 11131213, or Letrika 11.131.213 — this is the direct replacement to consider.
Manufactured to Denso's OSGR (Over-running Sprag Gear Reduction) design, the unit delivers reliable cranking performance through a compact, gear-reduced architecture that reduces mechanical stress on the ring gear at start-up. The 10-tooth pinion engages with clockwise rotation, and at 4.0kW output it provides the sustained cranking force demanded by large agricultural diesel engines. Being supplied brand new, there is no exchange core to return and no worn components to factor in.
Fitment covers 80 Case applications, including the 1620, 1640, 1644, 1666, 1668, 1670, 1680, and 1688 combine models across model years spanning 1985 to 2002. The part cross-references 34 OE and aftermarket references in total, including numbers from Denso, Remy, Iskra, Mahle, and Letrika — use the selection widget or search by OE number to confirm the match for your machine.

A. OSGR stands for Over-running Sprag Gear Reduction. The gear-reduction design allows the motor to operate at higher speed internally whilst delivering controlled, lower-speed cranking torque to the ring gear, reducing mechanical shock at engagement. The over-running clutch in the drive allows the pinion to disengage cleanly once the engine fires, protecting the starter from over-speed damage.
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.
