CAT Caterpillar 10R-7228 Electronic Unit Injector EUI - Used

Caterpillar Electronic Unit Injector (EUI), printed number 10R-7228, with follower, return spring assembly, two-post solenoid connector, and capped nozzle. Body is cast-marked CAT.

Application: Not verified. This injector is associated with Caterpillar electronic engine applications, but the exact engine family for this number has not been confirmed and no marine application is claimed. Cat injector numbers within the same family differ by calibration and are not automatically interchangeable — verify against your engine serial number and arrangement number before ordering.

Condition: Used, untested take-out. The unit appears complete with no visible cracks or impact damage; light surface staining is present and the body O-rings should be replaced on installation. No bench test, flow test, or engine run has been performed, and no operational claim is made. Recommended that the buyer have the injector flow-tested by a qualified diesel injection shop before service.

Ships drained with the nozzle capped and terminals protected.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
