⚙️ Key Features

• Fits 31 applications across D engines
• 0.122 kg
• No published length or diameter — measure the old sleeve

🔌 Function

Sets and holds a fixed gap between two components on a bolt or shaft, so the clamping load passes through the sleeve rather than crushing what is between.

⚠️ Common Signs of Failure

• Component sitting loose or rocking on its mounting
• Sleeve ends bruised, burred or crushed
• Bore worn oval or scored
• Fretting marks or corrosion where the sleeve meets its faces
• Fastener through the sleeve repeatedly working loose

🛠️ Service Notes

• Spacer sleeves 977799 and 977801 are the other two listed here, both far lighter and both against different application sets
• Check the faces the sleeve bears on for bruising; a dished face will let the joint work loose again

📦 Condition

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