# 3801515 Longblock | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured long block from the Engine group, weighing 1363.95 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. In the D16 industrial tables it is the long block listed with cylinder head 3801803, unit injector 3801396 and turbocharger 3801421, and no short block is catalogued for that engine. Four other long blocks here fall within 22 kg of it, so the part number is the only reliable identifier. It is supplied on an exchange basis: core deposit 3804515 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
