This is a new, genuine Kubota alternator assembly, part number 1E994-64010. It is a 12 V, 40 A unit with a P terminal, and it is Kubota’s current number for alternators 16678-64010, 16678-64012, 16678-64013 and 16678-64014. Kubota engine parts dealers list it for some builds of the Super Mini D722, D902 and Z602, the 05 Series D905, D1005, D1105, D1305 and V1505, and the WG1605.

Kubota built these engines with a dynamo or with a 30 A, 40 A or 60 A alternator, so the engine model alone does not pick the part. This is the 40 A unit with the P terminal, the tap some machines use for a tachometer or hour meter signal. Before you condemn the old alternator, check charging voltage at its output with a good battery, then the belt, the plug and the grounds.
