BMW Germany Belt Tensioner Damper Body Cast No. 1128-7 786 880 - Used

BMW cast-aluminum accessory / V-ribbed belt tensioner damper body, marked "BMW Germany" with casting number 1128-7 786 880 and a two-bolt mounting flange.

Application: Not verified. Visually consistent with the BMW belt-tensioner family used on M47/M57 diesel and related BMW inline engines (E39 / E46 / E53 era) — possible application only, not a confirmed fit. The number on this part is a casting number, not a confirmed orderable OEM service number, and must be verified against the BMW parts catalogue.

Condition: Used, untested take-off. Finish largely intact with light scuffs and surface dirt; no cracks, no broken ears, no visible corrosion. Tensioner arm and pulley are NOT included — damper/housing unit only, exactly as pictured. Spring tension, damping and bearing condition have not been tested.

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.
