Case IH International 385 484 485 584 684 784 Tractor Starter Motor | 12V 2.8kW 10-Tooth CW | OEM 537140R96

Nobody writes love songs about solenoid contacts, but on a forty-year-old International they are the difference between feeding the stock before breakfast and cranking a handle in the dark, and on the 385, 484, 485, 584, 684 and 784 that moment usually arrives after four decades of cold mornings, not because anything was built badly but because brushes are consumables the way tyres are. The replacement sold here carries Case IH reference 537140R96, built to the original Lucas M127 layout, and the crowd of numbers that follows it around — Delco on one box, Bosch on another, Iskra or Mahle on a third — says more about how many companies catalogued these tractors over the years than about any doubt over what the part actually is.

Fitment and Purchase Checks

Tractors of this age deserve one honest warning, which is that build runs overlap and the parts books contradict each other more often than anyone admits, so although the catalogues put 537140R96 across the 385 (1985 to 1990), the 484 (1977 to 1982), the 485 (1981 to 1991) and the 584, 684 and 784 (1977 to 1984), none of them will tell you which variant your particular month of production took.

The plate on your actual machine outranks every chart. So the sensible order of operations is old unit first — read what is left of the number on it, and if rust has been eating the stamping for a decade, a phone photo beats guesswork every time. Dealers and repair shops who send the serial and engine details across with the enquiry get back a proper quote with a price, stock, a dispatch date and warranty terms that hold where the part is actually going.
