3801504 Longblock | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured long block for the TAD941GE, from the Engine group, weighing 920 kg and listed for 1 application on TAD-series engines. 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. The reman table for the TAD941GE lists it with cylinder head 3801426, unit injector 3801440, turbocharger 3802156 and circulation pump 3803930, and no short block is catalogued, so this is the lowest-level exchange assembly available. It is the lightest of a trio spanning 2.6 kg, with 3801502 at 921 kg and 3801503 at 922.6 kg covering different engines. It is supplied on an exchange basis: core deposit 3804504 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
