🔌 Function

Gives the yoke and its shaft a true bearing or pivot surface, so the selector movement stays precise and the wear falls on the sleeve rather than the parts either side.

⚠️ Common Signs of Failure

• Slack or play felt at the shift lever before anything engages
• Gear selection vague, or the drive not always taking up
• Clicking or knocking from the linkage as the shift is worked
• Sleeve found oval, scored or worn thin on strip-down

🛠️ Service Notes

• Check the shaft and yoke for matching wear while the sleeve is out - fitting a new sleeve onto a worn shaft leaves the play behind
• Sleeves like this are cheap and awkward to reach, so renew it whenever the linkage is stripped for other work
