Product Number: 19994N
The WAI 19994N is a brand-new 12V 4.0kW starter motor. It is built to Denso OSGR specification, supplied as a direct replacement for Denso original-equipment number 428000-7360 and the Case and New Holland part number 504357253. OSGR (Off-Set Gear Reduction) design delivers reliable cranking torque through a compact, gear-reduced drivetrain — the format Denso specifies on a wide range of diesel plant and agricultural applications.
Running at 12 volts with a 4.0kW output and a 10-tooth drive pinion, the unit turns in a clockwise direction. These figures match the original Denso specification exactly, so no adaptation or modification is required at installation. Condition is brand new — not remanufactured — meaning all internal components are manufactured to tolerance from the outset, with no core deposit required.
WAI is a Denso-authorised manufacturer of starter motors and alternators, and the 19994N is produced under that arrangement to meet Denso's own dimensional and performance standards.

A. Yes. The WAI 19994N is a direct replacement for Denso original-equipment numbers 428000-7360 and 4280007360. It is built to Denso OSGR specification and supplied brand new. To confirm it is the correct unit for your application, search our cross-referenced catalogue by OEM number or ask Simon.
A. The WAI 19994N cross-references directly to Case part number 504357253 and New Holland part number 504357253. If you have that number on your existing starter or in your parts manual, this unit is the listed replacement. Use the selection widget or search by OEM number to verify fitment for your specific machine, or ask Simon — every cross-reference shown is backed by our Fit Guarantee.
A. The 19994N is a 12V, 4.0kW starter motor in Denso OSGR (Off-Set Gear Reduction) design. It has a 10-tooth drive pinion and clockwise rotation. The unit is brand new — not remanufactured — so no core deposit is required.
A. OSGR stands for Off-Set Gear Reduction — a design in which a small gear train reduces motor speed to increase pinion torque, allowing a physically compact unit to deliver strong cranking force. It is a specific Denso architecture, and the WAI 19994N replicates that design exactly. It will only fit applications that were originally equipped with an OSGR-type starter; fitting an OSGR unit in place of a different design type is not recommended without confirming compatibility.
A. The WAI 19994N is brand new. All internal components are manufactured to tolerance from new — this is not a remanufactured or reconditioned starter motor, and no core return or surcharge applies.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
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.
