• 133 applications across D, TAMD, HS and MD series

🔌 Function

⚠️ Common Signs of Failure

• Adjustment drifting out of position as the nut loosens
• Threads galled, stretched or stripped
• Nut faces rounded off by tooling
• Rust locking the nut so it will not move
• Knocking or movement at the joint the nut secures

🛠️ Service Notes

• Adjusting screw 3839410 and sleeve 3839411 sit in the same Engine group across the D, TAMD and MD engines and are worth ordering together when the assembly is stripped
• Clean the mating threads and tighten to specification against a clean face
