21111123 Liner | Genuine Volvo Penta Part

🔧 Product Description

Brand-new genuine Volvo Penta cylindrical liner used inside the D13/D16 plate heat exchanger—not an engine cylinder liner. Two liners locate the top-plate assembly around the end spacer tubes and maintain accurate alignment through the plate stack.

🚤 Compatibility

• Engine Family: D

⚙️ Key Features

• Heat-exchanger locating liner
• Two used per applicable heat exchanger
• Fits with spacer tube 21111110 and collar 21111128
• Maintains concentric top-plate alignment
• One liner supplied
• Engine type: Volvo Penta D13 and D16 marine diesel
• 2 used per assembly

🔌 Function

Locates and supports the heat-exchanger structural components so the plate pack remains centred during assembly and operation.

⚠️ Common Signs of Failure

• Corrosion or wear at the liner bore
• Loose top-plate location
• Misaligned spacer tube
• Uneven gasket compression
• Difficulty inserting the retaining hardware

🛠️ Service Notes

• Two of these liners are fitted per heat exchanger — renew both together rather than one, since they locate the same plate stack and uneven wear between the pair will throw the pack out of alignment
• Check the liner bore and its mating collar (21111128) for wear or scoring before reassembly; the liner's job is to keep the stack centred around the spacer tube, and a worn liner lets the pack shift under vibration
• At 45g this is a small precision spacer rather than a structural part — bag and label it separately during a heat-exchanger strip-down so it isn't lost among gaskets and fasteners
