Alternator for Kubota RTV900, RTV1140 & RTV-X900 Utility Vehicles

Fits Kubota RTV900, RTV1140 and RTV-X900 Series Utility Vehicles

This alternator is a direct replacement for the original unit fitted to Kubota RTV900, RTV1140 and RTV-X900 utility vehicles powered by the 3-cylinder diesel engine. It is built to OEM specifications for fit, form and function, so it bolts straight into the original mounting points without modification.

The unit is a 12-volt, 55-amp alternator with clockwise rotation, an internal regulator (IR) and internal fan (IF), matching the specification of the original Kubota part. It uses a single-groove (V1) pulley and an IG-L plug configuration, and the internal regulator is fitted with L-output as per the original design. The same alternator is also used on several Kubota B Series compact tractors and the ZD1511 zero-turn mower.
