🔌 Function

The sleeve controls component spacing and provides a rigid bearing surface for the mounting fastener.

⚠️ Common Signs of Failure

• Sleeve worn, oval or cracked
• Fretting at the sleeve ends
• Component misalignment
• Fastener unable to clamp correctly
• Excessive movement at the joint

🛠️ 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
