⚙️ Key Features

• 0.023 kg
• 145 applications across the AQ, AD, D, TMD, BB and MS families
• Sets assembly preload

🔌 Function

Sets and holds the preload on the assembly it fits into, its length fixing how much the parts either side are drawn together as the fastener is tightened.

⚠️ Common Signs of Failure

• Assembly slack or loose despite the fastener being tight
• Sleeve found crushed, collapsed or shortened
• Fretting or polished bands where the sleeve bears on its neighbours
• Preload that cannot be brought back within specification on reassembly

🛠️ Service Notes

• Renew rather than reuse - a sleeve that has already been drawn down once will not set the same preload again
• Check the faces either side of the sleeve for the bedding-in marks that show it was crushed rather than just seated

📦 Condition

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