DeWalt N390874 Spare Part - CON ROD

N390874

Genuine DeWalt connecting rod (part no. N390874) — the internal con‑rod that links the motor/crank to the hammer piston in select SDS‑Plus rotary hammer drills, restoring correct hammer action and impact transfer when the original rod is worn or damaged.

Precision‑machined metal construction for durability under repetitive impact; supplied as a single replacement piece designed to fit into the factory hammer assembly without modification.

Common fitment examples: DeWalt DCH283, DCH293, DCH323, DCH333, DCH334 and rotary hammer models D25333K / D25334K.

Simple swap during a standard strip‑down: replace the worn con‑rod to eliminate excessive play, metallic knocking or loss of impact and return the hammer mechanism to factory performance. Supplied as the original DeWalt part N390874.
