Service and Replacement Notes

For overhaul-kit purchases, exact fitment matters more than visual similarity. Kit configurations can differ between engine variants even when the base family is the same. Confirm the catalog part number and every relevant engine suffix or application code shown on your existing documentation before placing the order.

Before Ordering

Fitment should be confirmed before purchase. Match part number KMP4740.EOK-6ALY first, then compare the complete engine/application code to your equipment or service documentation. Contact your parts source for verification when the original number is unavailable.
