Product Number: 19747N
The WAI 19747N is a brand-new 12V 2.5kW starter motor. It is built to Denso OSGR specification, replacing original-equipment Denso units including references 128000-9970, 128000-9971 and 128000-9972. It is cross-referenced to Komatsu part number 600-813-1420 and fits the Komatsu FD20 forklift series, covering production years from 1991 through to 2005.
As an OSGR (Over-running Sprag Gear Reduction) design, this starter delivers its 2.5kW of cranking power efficiently through a gear-reduction drive, which reduces load on the battery and extends solenoid life compared with direct-drive equivalents. Clockwise rotation and an 11-tooth pinion gear match the ring-gear engagement geometry of the original Denso unit precisely, so no modification is required on installation.
Supplied brand new — not remanufactured — the 19747N is a direct replacement for worn or failed starters on Komatsu FD20 forklifts, an application where reliable cold-start performance in warehouse and yard environments is critical.

A. The WAI 19747N is supplied brand new — it has not been remanufactured or reconditioned. It is a direct replacement for the original Denso OSGR unit.
A. The 19747N operates at 12V with a power output of 2.5kW, uses a clockwise-rotation OSGR (Over-running Sprag Gear Reduction) drive, and has an 11-tooth pinion gear. These match the original Denso starter specification for the Komatsu FD20 without any modification.
A. OSGR stands for Over-running Sprag Gear Reduction. The gear-reduction mechanism lowers the motor speed relative to the pinion, allowing more torque to be produced at lower current draw compared with a direct-drive starter. The over-running sprag clutch disengages the pinion cleanly once the engine fires, protecting the motor armature from back-spin damage.
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.
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.
