⚙️ Key Features

• 0.054 kg
• Supersedes 3828663
• 55 applications across four engine series

🔌 Function

Sets the standoff between the parts it sits between, holding the correct gap when the fastener is drawn up.

⚠️ Common Signs of Failure

• Fastener not pulling up to torque, or the joint feeling spongy
• Sleeve crushed, belled or cracked at an end
• Component sitting at the wrong height or out of line
• Fretting or corrosion on the sleeve ends

🛠️ Service Notes

• A spacer sleeve sets a fixed length in the joint — never leave one out, shorten one, or substitute a stack of washers, or the clamping load and alignment will both be wrong
• Check that the sleeve is square and fully seated in its counterbore or recess before any fastener is tightened
• Discard a sleeve that is crushed, bell-mouthed, scored or corroded; a shortened sleeve lets the joint be over-clamped and the component distorted
• On sleeves in an oil circuit, make sure the bore is clear and that any seal running on the sleeve has a clean, unscored surface to work against
• Tighten the joint to the figure in the workshop manual for your engine, with the sleeve taking the clamping load rather than the component it protects
