466384 Valve Spring | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta valve spring from the Engine group, weighing 0.070 kg and listed for 68 applications across the TD, TMD, TWD, TID, AQD and TAMD series. It carries no build restriction, while valve spring 466383 covers the same 68 applications only up to serial number 2071104427 and weighs 0.029 kg, so the two are clearly different springs.

🚤 Compatibility

• Engine Family: TD, TMD, TWD, TID, AQD, TAMD, D, THAMD, TAD, MD
