22181757 Lock Washer | Genuine Volvo Penta Part

🔧 Product Description

Hardened axial locking washer used to retain a shaft, gear, bearing or rotating component in its specified position. Its tab, tang or locking profile is matched to the associated nut and shaft feature.

⚙️ Key Features

• Hardened spring/locking material
• Application-specific tab or tang geometry
• Prevents loosening under rotation and vibration
• Maintains axial retention of the serviced component
• Single-use replacement is recommended after tabs are bent or disturbed

🔌 Function

Mechanically locks the associated nut or shaft component against rotation and axial loosening.

⚠️ Common Signs of Failure

• Broken or flattened locking tab
• Nut movement or loss of preload
• Fretting around the washer faces
• Cracking from repeated reuse
• Axial play in the retained gear, bearing or shaft

🛠️ Service Notes

• Lock washers are single-use: the spring or the lock is set by the first tightening, so fit a new one whenever the fastener is disturbed
• Refit in the same arrangement as the parts came off, with the washer bearing on a clean, flat, undamaged seat
• Where the washer is a tab or bent type, bend the tab firmly against a flat of the fastener after final tightening, and never bend the same tab back and forth twice
• Tighten the fastener to the figure in the workshop manual for your engine — a lock washer secures a correctly tightened fastener, it does not compensate for a slack one
