Caterpillar 3126 Injector Rocker Arm Shaft Assembly - Used

Caterpillar-style injector rocker arm shaft assembly, tagged "3126 ROCKER ARM INJECTOR" by the removing shop. **Application:** Believed to be a Caterpillar 3126-family inline-6 diesel (marine / truck / industrial). No OEM part number or data plate is visible, so the application is unverified — it may fit CAT 3126 series engines; buyer must confirm. **Condition:** Used take-off, untested. Complete-appearing one-piece rocker shaft with rocker arms, pedestals, adjusting screws and locknuts; light surface oxidation and oil film from storage. Not tested, not rebuilt, and not measured to OEM specification — offered as a used/untested assembly or rebuildable core. We can provide additional close-up photos of any casting numbers and tape measurements on request. 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.
