Frequently Asked Questions

Will this alternator fit my Bobcat or Clark loader without modification?

Yes. This is a direct OEM-fit replacement built to the same specification (12V, 55A, IR/EF, CW rotation, V1 pulley) as the original unit, so no modification is required.

My model is not listed with a year - will it still fit?

Where our supplier data does not publish a year span we list the model only. The safest check is to compare the OEM number stamped on your existing alternator against the cross reference table above.

What's included with this part?

You receive the alternator unit only. Mounting hardware and pulleys are not included unless already fitted to the original unit you are replacing.

How can I tell my old alternator has failed?

Common signs include a warning light staying on, dimming or flickering lights, a dead or slowly draining battery, or unusual whining noises from the unit.

What does IR/EF mean?

IR/EF stands for Internally Regulated, Externally Fan-cooled - the voltage regulator is built into the alternator body and cooling air is drawn in by an external fan.
