3803892 Cylinder Head | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head for the D1-20, D1-20B and D1-20F, weighing 8.09 kg. Reman cylinder heads come ready for installation with the valves and springs already fitted, and with camshaft-bearing housings included where the design has them. With 3803891 at 5.87 kg it forms the pair of small D1 heads among the thirteen reman heads listed here, the rest of which run from 16 kg to 227 kg; the two are separated by engine rating, this one taking the D1-20 engines and 3803891 the D1-13, so match the engine plate rather than the 2.2 kg between them. Supplied on exchange, so a core fee is added to the invoice and refunded when the worn head is returned.
