Aluminum Flywheel Housing / SAE Bell Housing for Inline Diesel Engine - Used

Used aluminum flywheel housing / SAE bell housing for an inline diesel engine. **Application:** engine make/model not verified — the casting closely resembles the Cummins B-series / QSB aluminum flywheel-housing family, but no legible OEM service part number is present, so fitment must be confirmed by measurement. The only markings found are cast foundry/casting marks ("MADE IN USA", "KPI PA6K", and a partially obscured cast number reading approximately 500617) — these are not orderable part numbers. **Condition:** used take-off, untested. Casting appears complete with no visible cracks; painted surface is dirty with staining and light surface rust. No flywheel, starter, seal, dowels, covers, or hardware included. Approximately 22 x 20 x 11 in, roughly 40 lb. Additional photos and dimensions available 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. No returns on electrical, used, special-order, or installed parts.
