Massey Ferguson tractors have an engine identification number stamped onto the crankcase of the engine. This is usually found on the right side, behind the oil filter. Some tractors will have the identification number stamped on the serial number plate, which is typically located near the injector pump. Other Massey Ferguson tractors may have the number stamped onto the engine block itself. Some models may also have the identification number inscribed onto a data plate that is located on the side of the engine block.
