🔧 Product Description

This genuine Volvo Penta cylinder liner Class D is a selective-size wet cylinder-liner service component used in the cylinder block and piston group. It is manufactured to the original Volvo Penta dimensions and interface requirements so the piston and rings operate in the correct bore with the specified liner height. Class D selective-size wet cylinder liner. Nominal bore 144.00 mm and overall length approximately 315.00 mm. Documented replacement-liner dimensions include approximately 158.95 mm outside diameter, 171.94 mm flange diameter and 2.00 mm top-land height. In service, it provides the replaceable precision bore in which the piston and rings operate; Class D identifies the required selective fit. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556532 against the installed assembly before ordering.

Provides the replaceable precision bore in which the piston and rings operate; Class D identifies the required selective fit. Confirm the class marking, bore condition and liner protrusion before installation; renew the associated liner seals and follow the specified clamping and measurement procedure.

⚠️ Common Signs of Failure

• Low cylinder compression, difficult starting or reduced engine output
• Excessive crankcase blow-by or increased engine-oil consumption
• Coolant contamination in the oil or combustion gas entering the cooling system
• Vertical scoring, glazing, cavitation erosion or corrosion on the liner wall
• Incorrect liner protrusion causing cylinder-head gasket sealing problems

🛠️ Service Notes

• The recorded dimensions for this specific liner — nominal bore approximately 144.00 mm, overall length approximately 315 mm — are the figures to check the old liner and the block against; do not assume they carry across to other Class D-graded liners in the range, which are sized differently
• Outside diameter (~158.95 mm) and flange diameter (~171.94 mm) are both larger than the bore, so the block counterbore and seating flange must be clean and undamaged before the liner is pressed home, and liner protrusion should be checked against the ~2.00 mm top-land height once it is seated
