Frequently Asked Questions
Will this alternator fit without any modification?
Yes. This is a direct OEM fit and function replacement using the same mounting, pulley and electrical connections as your original unit, so no modification is needed.
What is included?
You receive one new alternator, ready to install using your existing bracket, belt and wiring loom.
How can I tell my old alternator has failed?
Common signs include a battery warning light, dim or flickering lights, a battery that won't hold charge, or a whining or growling noise from the alternator itself.
My equipment isn't a Kubota tractor - will this still fit?
This alternator is used across a wide range of equipment built around the Kubota diesel engine, including excavators, skid steers, mowers and forklifts. Check the OEM cross reference table above against your existing alternator's part number to confirm a match.
