Fitment FAQ

Questions buyers ask before requesting a quote.

How do I match an excavator alternator?

Use the complete reference number first, then compare voltage, output, pulley, mounting ears, terminals and engine application with the original unit.

Can pulley differences affect alternator fitment?

Yes. A matching alternator body may still be unsuitable if the pulley type, groove count or alignment differs from the original installation.
