21334768 Cylinder Liner — Volvo FH12 FH16

This cylinder liner is a crucial component within the engine's combustion chamber, forming the inner wall of the cylinder bore. It is precision-engineered to withstand extreme temperatures and pressures, providing a smooth, durable surface for the piston rings to seal against, unlike a worn liner which would exhibit scoring, ovality, or pitting. Operators may experience a loss of engine power, increased oil consumption, blue smoke from the exhaust, or rough idling when cylinder liners begin to fail.

Failure Symptoms

Increased oil consumption and visible blue smoke from the exhaust are often the first signs of worn cylinder liners. As the condition worsens, engine power will noticeably decrease, and the engine may start to run roughly or misfire due to poor compression. If left unaddressed, the scoring or wear can lead to catastrophic engine damage, such as a piston seizure or connecting rod failure.

Installation Tip

Ensure the cylinder block deck surface is perfectly clean and free of any debris or old gasket material before installing the liner. Improper seating can lead to coolant leaks or premature liner failure.

Service Note

Always replace piston rings and inspect pistons for wear or damage when replacing cylinder liners.
