• Component it retains found loose or able to move endwise
• Ring sprung, distorted or missing from its groove
• Groove edges hammered or worn wide
• Rattle or ticking from the assembly the ring should hold

🛠️ Service Notes

• Ask us to confirm supply before planning the job around it
• Old number 875429 is also listed as superseded by gasket 808275, so order by the current number rather than that shared old reference
