1590076 Spacer Sleeve | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta spacer sleeve within the Marine Propulsion group, used at engine mounting and bracket locations on D9 series marine diesel engines. It sets and maintains the correct standoff distance and bolt alignment at the joint so clamping load is carried properly through the assembly.

🔌 Function

A spacer sleeve maintains a fixed distance between two mounting faces and keeps the through-bolt correctly located, so fastener clamping force is transferred evenly through the joint. It prevents the mounted component from being crushed or misaligned when the fastener is torqued.

⚠️ Common Signs of Failure

• Visible crushing, deformation or ovalling of the sleeve
• Corrosion, pitting or surface scoring on the sleeve body
• Bolts that will not hold torque or work loose in service
• Excessive movement or noise at the mounting point under load
• Elongated or worn bore allowing the bolt to shift position

🛠️ 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
