1678297 Spacer Sleeve | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta spacer sleeve is a machined spacing component listed across the D4, D6 and D13 engine ranges. Volvo Penta lists it in a wide spread of assemblies, including the turbocharger, the fuel injection pump, the alternator and its guards, the belt guard, the radiator and the oil filter housing, where it sets the designed standoff on a fastener and carries the clamping load across that gap so the components either side are not drawn together. Volvo Penta gives a length of 14.2 mm and a weight of 0.023 kg, and notes that it should not be used where a clutch casing for a power take-off is installed. The fitted quantity varies from one assembly to the next, so confirm the quantity for your engine as well as the part number 1678297 and the exact model before ordering.

🔌 Function

The spacer sleeve sets a fixed distance between two components on a common fastener or shaft, holding the correct standoff as the joint is tightened. It carries the clamping load across that gap so the components are not drawn together.

⚠️ Common Signs of Failure

• Incorrect component spacing or alignment on assembly
• Crushing, deformation or shortening of the sleeve under clamping load
• Wear or scoring on the sleeve ends
• Corrosion or pitting of the sleeve body
• Fasteners losing torque as a deformed sleeve settles

🛠️ 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
