🔧 Product Description

This is a genuine Volvo Penta spacer sleeve supplied in the 22 mm inside diameter, 2000 mm length size, used within the lubricating and oil system. It is cut or fitted to length to space, protect and support oil return pipework and adjacent components.

🔌 Function

The spacer sleeve provides support, spacing and protection around oil return pipework in the engine's lubrication system. It helps maintain correct component positioning and guards against direct contact, chafing and vibration damage.

⚠️ Common Signs of Failure

• Oil weeping or leakage around the pipe or joint the sleeve supports
• Visible cracking, splitting or hardening of the sleeve material
• Chafe marks or wear through the sleeve wall where it contacts adjacent components
• Loose or displaced sleeve allowing the pipe to move or vibrate
• Collapsed or deformed sleeve causing misalignment of the oil return line

🛠️ 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
