# 3803525 Cylinder Head | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head, weighing 36.286 kg and listed for 12 applications across the TWD740, TAMD74, TAMD75 and TAD740 range. The reman catalogue lists this number against the TAMD74C-A, TAMD74L-A and TAMD74P-A. It is supplied ready for installation with valves and springs fitted, and camshaft-bearing housings included where applicable. Cylinder head 3803286 at 37.647 kg sits close enough that weight is no guide, so order on the engine designation. Supplied on an exchange basis: core deposit 3806525 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
