3801568 Longblock Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured longblock from the Engine group, weighing 986.56 kg and listed for 1 application on TAD-series engines. It supersedes part number 3801687. Longblock 3801510 is only 2.7 kg lighter and covers 5 applications, so the part number decides. This unit is supplied on an exchange basis: core deposit 3804568 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
