Product Number: 19188N
The WAI 19188N is a brand-new 12V 2.0kW starter motor. It is built to the OSGR (Off-Set Gear Reduction) design and manufactured by Poonsung. It is a direct replacement for Delco Remy DRS0237, Cummins 4900574, DRI 683044152, and Poong Sung / POONGSUNG 031013180 / 03101-3180, making it a verified cross-referenced choice for buyers sourcing by OE number.
The OSGR design positions the reduction gear set off-axis from the armature, delivering strong cranking torque relative to motor size — a layout well suited to the heavier-duty diesel and industrial engine applications these references commonly serve. With clockwise rotation and a 15-tooth pinion, the motor is built to exact engagement specifications and is supplied brand new, not remanufactured.
At 12V and 2.0kW output, the 19188N meets the power requirement for the engine platforms these OE numbers cover. All key parameters — voltage, power, rotation direction, tooth count, and design type — are confirmed in the specification table below.

A. The 19188N is cross-referenced to five OE numbers: Delco Remy DRS0237, Cummins 4900574, DRI 683044152, POONGSUNG 03101-3180, and Poong Sung 031013180. If you are sourcing by one of these numbers, this is the confirmed replacement. To verify fit against your engine or machine, search our cross-referenced catalogue by OEM number or machine model, or ask Simon.
A. The 19188N carries Cummins reference 4900574, confirming it is cross-referenced to a Cummins original-equipment starter. To identify whether your specific Cummins engine variant is covered, search our catalogue by your engine model or OEM part number, or ask Simon. Every OE cross-reference shown is backed by our Fit Guarantee.
A. The WAI 19188N runs on 12V, produces 2.0kW of output power, uses an OSGR (Off-Set Gear Reduction) design, has a 15-tooth pinion, and rotates clockwise. It is supplied brand new by Poonsung. Full specifications are in the table on this listing.
A. OSGR stands for Off-Set Gear Reduction. In this design, a planetary or spur gear set reduces the armature speed before it reaches the pinion, increasing cranking torque without requiring a larger or heavier motor. This makes it a practical choice for diesel and industrial engines where high initial torque is needed to turn over the engine against compression.
A. It is brand new. The 19188N is not a remanufactured or reconditioned unit — it is supplied new by Poonsung.
A. Yes. Delco Remy DRS0237 is one of the five confirmed OE cross-references for the WAI 19188N. It is the highest-demand reference for this part. If you are replacing a DRS0237, the 19188N is the verified cross-referenced substitute.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
A. Compatible spares and accessories are shown on the Related Accessories tab of this product page, and common parts across the brands we stock are in our Parts & Spares section.
