This is a new, genuine Kubota alternator assembly, part number 1G874-64010, rated 12 V and 30 A. Kubota engine parts catalogs list it for the Super Mini and 05 Series diesels and name the D722, Z482, D905, D1005 and D1105. It is the current replacement for alternators 16231-64010, 16231-64012, 16231-64013, 16231-64014 and 16231-64015, and Kubota dealer catalogs list it for the G2160, G2460G and TG1860 lawn and garden tractors.

Replace an alternator when charging voltage stays low with a good battery and clean connections, when the charge light stays on, or when a bearing gets noisy. Test output at the alternator and check the belt and the wiring before you condemn it. Kubota builds these engines with more than one alternator. This is the 30 A unit. The 40 A alternator 1J022-64010 and the 60 A alternator K7561-61920 are separate parts.

Frequently Asked Questions

Will the 1G874-64010 fit my Kubota D1105?

Kubota engine catalogs list it for the D722, Z482, D905, D1005 and D1105. Kubota also builds 05 Series engines with 40 A and 60 A alternators under other numbers, so call 530-668-0818 with your engine serial number and the number on your old alternator.

What numbers does the 1G874-64010 replace?

Kubota 16231-64015 and the earlier 16231-64014, 16231-64013, 16231-64012 and 16231-64010. If your old alternator carries one of those numbers, this is the current part.

Does it fit the Kubota G2160 or TG1860?

Kubota parts lists show alternator 16231-64015 on the G2160, G2460G and TG1860, and 1G874-64010 is the current replacement for that number. Early tractors can carry a different alternator number, so send us the tractor serial number and the number on your old alternator and we will check it.

How is it different from the 1J022-64010?

Output. The 1G874-64010 is the 30 A alternator and the 1J022-64010 is the 40 A alternator. They are separate part numbers, so order the one that matches your old unit.
