This is a new, genuine Kubota starter motor, part number 1K371-63010. It is a 12 V, 2.0 kW unit with a 9-tooth pinion for Kubota 03 Series engines, and it is listed for the V2203 and V2403 four-cylinder diesels.

Replace a starter when it clicks but will not turn, cranks slowly on a good battery, grinds on engagement, or pulls too much current. Rule out the battery, cables, grounds and the start signal first, since they cause many no-crank calls on small Kubota engines.
