Product Number: 18154N
The WAI 18154N is a brand-new 12V 2.0kW starter motor. It is built to the Denso OSGR (Off-Set Gear Reduction) design, cross-referenced to Kubota original-equipment numbers including 15425-63010, 15425-63011, 15425-63012 and 15425-63013, as well as Denso references 028000-9030, 028000-9031 and 028000-9032. It is a direct replacement for worn or failed units on Kubota and Thomas Equipment machines across a total of nine confirmed applications.
The OSGR design positions the reduction gear off-axis from the motor shaft, delivering strong cranking torque from a compact envelope — well suited to the diesel engines found in Kubota compact excavators and wheel loaders. The unit runs at 12 volts, produces 2.0kW of output power, turns clockwise, and engages via a 9-tooth pinion. It is supplied as a complete, ready-to-fit assembly in brand-new condition — not a remanufactured or exchange unit.
Confirmed fitment covers six Kubota models — including the KX121-2, KX161-2, R510 and R520BU-1A — and three Thomas Equipment models, including the T173 and T183. The full 20-reference cross-reference list spans Bosch USA SR10104X, Remy 69025 and Universal UNS1790 in addition to the Kubota and Denso numbers noted above.

A. It cross-references to six Denso numbers — 028000-9030, 028000-9031, 028000-9032, 0280009030, 0280009031 and 0280009032 — as well as Bosch USA SR10104X, Remy 69025 and Universal UNS1790. All 20 cross-references are available in our catalogue; search by any OE number to verify your application.
A. The WAI 18154N operates at 12V, delivers 2.0kW of output power, and uses a Denso OSGR (Off-Set Gear Reduction) design. It rotates clockwise and engages with a 9-tooth pinion. It is supplied brand new — not remanufactured.
A. OSGR stands for Off-Set Gear Reduction. In this design the reduction gear sits off-axis from the motor shaft, which allows high cranking torque to be generated from a physically compact unit. This is well suited to the smaller diesel engines found in Kubota compact excavators and wheel loaders where underbonnet space is limited.
A. This is a brand-new starter motor. It is not a remanufactured, reconditioned, or exchange unit, so there is no core charge and no old unit to return.
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.
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.
