Knowledge base for the Yanmar New Super Forte series: F195, FX195, F215, FX215, F235, FX235, F255, FX255, F265 and FX265 (D = 4WD, approx. 1987–1992). These compact diesel tractors share one family, but differ in engine: the F/FX195 has the 3-cylinder 3TNB80 (1327 cc, 80 mm bore), the F/FX215 the 3TNB82 (1394 cc, 82 mm bore), and the F/FX235, F/FX255 and F/FX265 the 3TNB84 (1463 cc, 84 mm bore). As a result, among other things, the cylinder head gaskets and piston rings are not interchangeable between the groups. F models have a standard gearbox, FX models have powershift (main shifting without clutch); the U version has OK-UFO lift electronics.
