Key Features

  • New injector rocker arm — not reconditioned

Texas Power injector rocker arm for Caterpillar 3406E and C15 engines, covering the 5EK, 6TS, 1LW, 2WS, 6NZ, and MBN serial prefixes. The injector rocker transfers cam lobe motion to the unit injector, so worn bushings, galled contact surfaces, or a loose adjusting screw translate directly into inconsistent injection timing and fuel delivery. Replacing worn injector rockers during an overhaul restores correct injector actuation across all six cylinders.

Please note: This is the injector rocker only, sold individually. A complete CAT engine uses six injector rockers and twelve exhaust rockers. Exhaust rockers are a separate part number and must be ordered separately. Confirm quantity before ordering.
