⚙️ Key Features

• 3.60 mm thick
• 21 applications across AQ and BB series engines
• One 0.05 mm step from 463551 and 463553
• Published weight of 0.024 kg does not track thickness across the series

🔌 Function

Packs a running clearance by a fixed amount, so it is chosen on measurement rather than by engine model.

⚠️ Common Signs of Failure

• Noisy valve gear or a distinct tap at idle
• Measured clearance out of specification
• Contact face polished, pitted or dished
• Wear concentrated on one side of the washer

🛠️ Service Notes

• Order on measurement, not on weight, as this washer is published lighter than the thinner 3.55 mm one
• Fit only one washer per location, never a stack of two to make up a size

📦 Condition
