Product Number: 19839N
The WAI 19839N is a brand-new 12V 2.5kW starter motor. It is manufactured by Mando to OSGR (Off-Set Gear Reduction) design, cross-referenced against Hitachi S13-41 and its variants, Yanmar original-equipment numbers 121254-77010, 121254-77011 and 121254-77012, and Delco Remy DRS0052, DRS0106 and DRS3245 — drawing on 32 OE references in total. It is a direct-replacement unit for Yanmar and John Deere plant and agricultural machinery spanning a range of diesel engine applications.
Mando is an established OE-tier supplier of rotating electrics, and this starter is built to their original specification. The OSGR design positions the reduction gear set off-axis from the main motor body, delivering efficient torque multiplication and a compact profile that suits the confined bays common to compact tractors and construction plant. Clockwise rotation, 15-tooth pinion geometry and 12V/2.5kW output are matched to the original Hitachi and Yanmar specifications the unit replaces.
Fitment covers Yanmar engine models including the 3D84-1C, 3T95, 4T95 and 4T95T (spanning build years 1980–2004), and John Deere skid-steer models 575, 675 and 675B (1987–1994) — 10 confirmed applications across both makes. Additional cross-references include Prestolite Electric 20513065, Sando 60201340, John Deere AM875415 and AM876224, and DRI 682012152 and 682013152.

A. The WAI 19839N is a 12V, 2.5kW starter motor of OSGR (Off-Set Gear Reduction) design, manufactured by Mando. It has a 15-tooth pinion and clockwise rotation. It is supplied brand new.
A. OSGR stands for Off-Set Gear Reduction. In this design, a planetary or spur reduction gear set is positioned off-axis from the main motor armature, which reduces the output speed of the motor into higher cranking torque at the pinion. The result is a compact unit that delivers strong starting performance — well suited to the confined engine bays of compact tractors and construction plant such as the Yanmar and John Deere machines this starter serves.
A. This unit is brand new — not remanufactured or reconditioned. It is manufactured by Mando to OE specification.
A. Yes. John Deere OE references AM875415 and AM876224 are included within the 32 cross-references held for this part. Search our cross-referenced catalogue by either number to confirm suitability for your John Deere machine.
