3801691 Turbocharger | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured turbocharger for the high rating, listed in the reman catalogue against the TAD552VE within the TAD550VE to TAD552VE group, weighing 8.23 kg and covering 3 applications across the TAD series. It has been replaced by 3801818, the current high-rating TAD552VE turbocharger, so treat this number as superseded stock. This unit is supplied on an exchange basis: core deposit 3804691 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
