Product Number: 18055N
The WAI 18055N is a 12V 0.9kW PMDD starter motor. It is built to the Hitachi specification, cross-referenced against 35 original-equipment part numbers including Hitachi S114-443, S114-653, and S114-816 variants. It is a brand-new unit — not remanufactured — making it a direct OE-quality replacement for compact tractors, mini-excavators, and diesel-engine plant across the Yanmar, John Deere, Takeuchi, and New Holland Industrial ranges.
The PMDD (Permanent Magnet Direct Drive) design eliminates the planetary reduction gear common to older starter architectures, giving a lighter, more compact unit with fewer internal wear surfaces. Clockwise rotation and an 8-tooth pinion match the original ring-gear engagement geometry, so no modification is required at installation.
Fitment covers 10 verified applications across four makes, including John Deere 330, 655, and 3375 farm tractors, the New Holland Industrial E15 compact excavator, Takeuchi TB007, and Yanmar 3TN63 and 3TN66 engine variants. Full application data is searchable in the cross-referenced catalogue by OEM number or machine model.

A. This is a brand-new starter motor — not remanufactured, reconditioned, or exchange. The WAI 18055N is supplied as a single new unit built to the Hitachi PMDD specification.
A. PMDD stands for Permanent Magnet Direct Drive. Rather than using an electromagnetic field coil or a planetary reduction stage, the motor uses permanent magnets and drives the pinion directly. The result is a more compact, lighter unit with fewer internal components and wear points compared with older gear-reduction designs. The 8-tooth pinion and clockwise rotation of this unit match the original ring-gear specification, so it installs as a direct replacement without modification.
A. Voltage: 12V. Power output: 0.9kW. Rotation: clockwise (CW). Pinion teeth: 8. Design: PMDD (Permanent Magnet Direct Drive). Manufacturer specification: Hitachi. Condition: Brand New. These figures match the original Hitachi S114-series specification this unit is built to replace.
A. Yes — the WAI 18055N has 4 verified John Deere applications, including the 330 farm tractor (1986), 3375 (1994–1999), 375 (1988–1993), and 655 (1989–1991). John Deere OE references covered include AM875014, AM878176, AM878813, AM880978, and SE501846. Use the selection widget or search by your John Deere model number to confirm fit, or ask Simon if your model is not listed.
