3801890 Cylinder Head Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head for the D4-300A-F, D4-300D-F and D4-300I-F, weighing 55.338 kg. Reman cylinder heads are supplied ready for installation with the valves and springs already fitted, and with camshaft-bearing housings included where the design has them. Its neighbour here is 3801889 at 54.885 kg, the head for the D4-180 to D4-260 F engines - 453 grams apart, so the engine rating is the only reliable guide. The catalogue lists this head alongside long block 3801702 and turbocharger 3801173 for the same engines. Supplied on exchange, so a core fee is added to the invoice and refunded when the worn head is returned.
