Product Number: 4319N
The WAI 4319N is a brand-new 12-volt starter motor. It is built to the Delco 25MT specification, replacing the original-equipment Delco unit (reference 1109257) on a range of Massey Ferguson agricultural machinery. It is a direct-drive (DD) design with clockwise rotation and a 10-tooth pinion — the same configuration as the factory-fitted Delco unit it supersedes.
Fitted vehicles span seven Massey Ferguson applications, covering models such as the MF-235 (1974–1976), MF-245 (1977–1980), MF-255 (1975–1976), MF-30E (1986–1992), MF-40E (1987–1992) and MF-50U (1976–1977). Being supplied as brand new rather than remanufactured means there are no worn internals to contend with, and the unit is ready to install without further preparation.
The 25MT series is a well-proven platform in the agricultural sector, and the DD (direct-drive) layout keeps the design straightforward and reliable in demanding field conditions. Lester reference 4319 provides an additional cross-reference point for workshop procurement.
