Diesel Engine Front Timing Gear Housing / Gear Case Cover Casting 489202-03 - Used

Cast-iron front timing gear housing / gear case cover for a marine or industrial diesel engine, carrying the casting number 489202-03 (cast into the metal — this is a casting number, not a confirmed OEM service part number). Features a machined block-mating face, crankshaft front seal bore, and a large bolted accessory/gear-drive opening at the top.

Application: not verified — engine make and model could not be confirmed from the casting or photos. This part is sold by photographs, identifiers, and dimensions. Our parts desk can help cross-reference the casting number if you provide your engine model and serial number.

Condition: used take-off, untested. Complete casting with chipped factory blue paint, surface rust on the lower flange, and old gasket residue on the machined faces. Not crack-tested or dimensionally inspected; the installed front seal should be treated as a replacement item.

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.
