# 3863066 Adjusting Washer | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta adjusting washer 3.05 mm thick, weighing 0.007 kg and listed for 16 applications across the DPH and D families. It is the thickest of the graded set yet carries the lowest published weight of the four, which cannot be right for a plain washer — treat the weight as unreliable and order on the 3.05 mm figure, with 3863063, 3863064 and 3863065 covering 2.85, 2.90 and 3.00 mm.
