3801502 Longblock | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured long block weighing 921 kg and covering five applications - TAD940GE, TAD940VE, TAD941VE, TAD942VE and TAD943VE. It is the single long block across both halves of the D9 listing, while the injector splits between 3803874 for TAD940VE and TAD941VE and 3801437 for TAD942VE and TAD943VE. A reman long block is defined as the cylinder block assembly with pistons, connecting rods, crankshaft, camshaft, cylinder heads, rocker mechanism, oil pan and valve cover - the intake and fuel system, exhaust manifold, turbocharger, oil cooler, circulation pump and flywheel housing belong to the complete engine package rather than to a long block. Reman components are restored to technically new condition, with wear parts and anything outside tolerance replaced by new genuine parts, built to a bill of material carrying all design changes so the unit meets the latest technical specification, then tested and painted before despatch. This is an exchange item: core deposit 3804502 is charged alongside it and refunded as soon as the worn long block is returned, and the core can go back once the new one is fitted and the engine is running again.

🔌 Function

Supplies the block, crankshaft, pistons, camshaft, cylinder heads and valve gear as one remanufactured assembly, replacing the core of a worn engine while the ancillaries carry over.

⚠️ Common Signs of Failure

• Low or uneven compression across the cylinders
• Heavy blow-by from the crankcase breather
• Knocking or rumbling from the bottom end under load
• Oil pressure falling away when hot
• Scored bores, picked-up bearings or a worn crankshaft found on strip-down

🛠️ Service Notes

• Order strictly by part number: long block 3801503 sits within 1.6 kg of this one and serves a different engine range
• Transfer or renew the intake and fuel system, exhaust manifold, turbocharger, oil cooler, circulation pump and flywheel housing, none of which are long block content
• Core deposit 3804502 is charged with this order and refunded when the worn long block goes back - the return can wait until the new one is fitted and the engine is running again

📦 Condition
