3801894 Cylinder Head Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head for the TAD650VE, weighing 62.50 kg and listed for one application in the TAD series. A Reman cylinder head is supplied ready for installation with valves and springs, and with the camshaft-bearing housings included where the design carries them. It supersedes part number 3801133, catalogued earlier simply as a cylinder head, and the reman catalogue lists it alongside engine 3801476, injector 3803976 and turbocharger 3801140 for the same engine. This unit is supplied on an exchange basis: core deposit 3804894 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

• Compression loss on a cylinder
• Cracks at the valve seats or injector bores found on strip-down
• Corrosion or pitting in the coolant passages

🛠️ Service Notes

• The TAD660VE takes cylinder head 3803974 instead, so check the designation before ordering
• Renew the head gasket set and head bolts, have the block face checked, and set the valve clearances and injector protrusion after fitting
• Correct the cause of the original failure so the new head is not damaged the same way, and return the core once the engine is running
