Cummins Flywheel Housing / Bell Housing Casting 3925234 - Used

Used cast-iron flywheel / bell housing carrying casting number 3925234 with original Cummins-blue paint. **Application:** believed to be from the Cummins B-Series diesel family (4BT/6BT type) — application is NOT verified; the housing is offered by photographs, cast identifiers, and dimensions only. Features a round SAE-style bell flange, machined block face with rear seal register bore, machined starter pad, inspection opening, and cast lower mounting bosses. **Condition:** used take-off, untested. Paint is worn and chipped with surface rust on bare iron; machined surfaces show normal service wear. No crack testing, magnaflux, or dimensional inspection has been performed and none is implied. Note that 3925234 is a casting number, not a confirmed orderable OEM service part number — verify the correct service number with Cummins using your engine serial/CPL. 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.
