🔌 Function

Clamps the alternator or its bracket to the engine, holding the unit in position and carrying the belt tension load through the joint.

⚠️ Common Signs of Failure

• Belt squeal or a rattle from the alternator as the joint works loose
• Charging output dropping in and out as the alternator moves on its mount
• Bright wear marks or fretting around the screw head and bracket face
• Thread found stretched, galled or pulled on removal

🛠️ Service Notes

• Two screws serve this installation - this 0.052 kg screw and the 100 mm long 0.038 kg screw 20460867 - so check the length required at your mounting point
• Inspect the bracket bore for wear or elongation whenever a mounting screw has come loose; a worn bore will not hold a new screw either
