It features a cast aluminum housing with a single-groove pulley and flange mounting configuration. The unit integrates a rectifier regulator (RS5101 / 15531-64601) for voltage control. This part supersedes earlier revisions 15531-64016, 15531-64013, and 15531-64010. It serves as a direct OEM replacement for charging systems on compact tractors, mini excavators, and utility vehicles equipped with Z482, D722, D750, D850, V1200, WG750, and DF750 engine series. Cross-reference interchange includes Kubota OEM numbers 6C040-59252 and 6A830-59250, as well as aftermarket identifiers GP8109 and regulator numbers 15531-64601, 15531-64603, RP201-53710. The alternator operates on negative ground electrical systems. Typical applications cover Kubota BX series tractors (BX1500, BX1800, BX2200, BX23), B series tractors (B2400, B2710, B6200, B7200), U series excavators (U10, U15, U17), and RTV500 utility vehicles.
