⚙️ Key Features

• Cotter from the Fuel System group
• 0.086 kg

• The lightest of three near-identical cotters covering the same engines, the others being 23021554 and 23021654

🔌 Function

Locks the parts it is fitted between, wedging into its groove so the assembly cannot work loose or move along its axis.

⚠️ Common Signs of Failure

• The retained component working loose or moving in service
• Cotter cracked, spread or partly backed out of its seat
• Seat or groove fretted bright where movement has started
• A hammering or knocking note from the joint under load
• Cotter corroded into place so it will not drive out

🛠️ Service Notes

• Seven grams will not tell these three apart by hand, so order strictly by part number
• Renew rather than reuse a cotter that has bedded in, and check the groove for fretting before refitting

📦 Condition

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