⚙️ Key Features

• Alternator, Charging, Electric Motor, Electric Drives group
• 0.039 kg
• 29 DPX applications
• Half the weight of bolt 3861016
• 2 used per assembly

🔌 Function

Clamps a charging or electrical drive component down onto its mounting so it cannot move under belt load and vibration.

⚠️ Common Signs of Failure

• Bolt found loose, or the component able to move on its mounting
• Thread stripped, stretched or galled
• Head corroded so the drive rounds out on removal
• Bolt bent or the shank polished where it has been working in its hole
• Belt tension drifting because a mounting bolt has slackened

🛠️ Service Notes

• This bolt and 3861016 sit exactly two to one on weight, so 3861016 is the longer or larger fastening - check which length the mounting needs
• Clean the thread and the seating face, and pull down to the specified torque rather than by feel, since an over-tightened alternator mounting will distort the bracket

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
