463561 Adjusting Washer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta adjusting washer 4.05 mm thick, from the Engine group, listed for 21 applications across AQ and BB series engines. It is published at 0.030 kg, exactly the same as the 4.10 mm washer 463562 and the 4.15 mm washer 463563, so the top three sizes cannot be told apart by weight at all.

• Clearance out of specification at service
• Contact face pitted, cupped or worn bright
• Uneven wear across the washer face
