463560 Adjusting Washer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta adjusting washer 4.00 mm thick, from the Engine group, listed for 21 applications across AQ and BB series engines. Its published weight of 0.019 kg is the lowest in a series that runs from 3.55 mm to 4.15 mm, even though seven of the eight sizes are thinner, so the weights cannot be trusted to identify a size.
