Massey Ferguson Tractor Starter Motor | 12V 10-Tooth CW | OEM 1860093M2

A 290 on the same farm since new is usually on its third starter, and the one it wants is this one. 1860093M2 is the Lucas M50-family motor in heavy direct-drive form, twelve volts and about 2.8 kW on an 89 mm three-hole flange, and the tractors it fits run from the 165 of 1964 to the 298 of 1986 because the engine bay barely changed while the sheet metal around it did.

Fitment and Purchase Checks

Catalogues disagree about these revisions because MF never retired the original number, and one digit separates a starter that bolts up from one that never quite reaches the flywheel. The old unit settles it faster than any table: read the plate, count the pinion teeth, measure across the flange, and send a photograph with the enquiry, and the quote comes back firm on price, stock, dispatch window and warranty terms for the destination.
