⚙️ Key Features

• Valve-train locating or retaining component
• Approximate weight: 0.304 kg
• Factory bore, thickness and profile
• Controls axial position or spring alignment

🔌 Function

The ring locates, retains or supports the assigned valve-train component and maintains the specified axial position.

⚠️ Common Signs of Failure

• Excessive axial movement
• Scoring or wear
• Incorrect spring or rocker alignment

🛠️ Service Notes

• Renew rather than reuse: rings of this kind seal or retain by being sprung or compressed into place and take a permanent set once fitted
• Clean the groove, register or bore the ring sits in and remove any burr or old sealing residue before fitting — debris in the groove stops a ring seating and is a common cause of a repeat leak
• Open or compress the ring only as far as it needs to go on; overstretching or twisting it during fitting distorts it permanently
• Check the ring is fully seated all the way round its groove or register, and the right way round where its faces differ, before closing the assembly up

📦 Condition

• Genuine Volvo Penta part
