🔌 Function

Clamps the belt-tensioning bracket assembly together, holding its parts in position against belt load and vibration.

⚠️ Common Signs of Failure

• Belt tension slackening off as the joint loses clamping load
• Rattle or knock from the tensioner mounting
• Socket found rounded or packed with dirt so a key will not grip
• Thread found stretched or galled on removal

🛠️ Service Notes

• Two hex socket screws serve this assembly - 0.038 kg here and 0.027 kg for 20499932 - so check the position before ordering
• Clean the socket out fully before undoing; a rounded socket on a tight screw turns a small job into a drilling job
