3801665 Longblock Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured long block built without VCB, from the Engine group, weighing 1009.24 kg and listed for 1 application in the TAD series. Volvo Penta define a long block as the cylinder block assembly with pistons, connecting rods, crankshaft, camshaft, cylinder heads, rocker mechanism, oil pan and valve cover, so the intake and fuel system, exhaust manifold, turbocharger, oil cooler and circulation pump all transfer from your old engine. It is the long block for the TAD1371VE to TAD1375VE group, listed with unit injector 3801469, turbocharger 3801536 and a choice of cylinder head - 3801571 without VCB or 3801572 with VCB; no short block is catalogued for this engine. It supersedes part number 3801567. It is supplied on an exchange basis: core deposit 3804665 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
