3803314 Cylinder Head | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head, weighing 19.709 kg and listed for 30 applications across the TD, TWD, TMD, TID, TAMD and TAD 121 and 122 range - the widest coverage of the eighteen heads listed here. The reman catalogue lists this number against the TAMD122A, TAMD122C, TAMD122D and TMD122A. It is supplied ready for installation with valves and springs fitted, and camshaft-bearing housings included where applicable. It supersedes 3803135, which the earlier listing carried as a cylinder head. Supplied on an exchange basis: core deposit 3806314 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
