🔌 Function

Locks a threaded joint in the mechanical speed, fuel-control or stop-linkage assembly, holding the adjustment where it was set.

⚠️ Common Signs of Failure

• Linkage adjustment drifting so idle or maximum speed changes
• Nut found finger-loose on inspection
• Thread found galled or the nut found seized by corrosion
• Rattle from the linkage as the joint slackens

🛠️ Service Notes

• Reset and recheck the linkage adjustment after fitting - a locknut that has been slack means the setting has already moved
• It replaces 20511890, so both numbers describe the same nut
