111-1815 Cylinder Liner — Cat 3054 3056

This is a precision-machined cylinder liner that forms the inner wall of the engine's combustion chamber, guiding the piston's movement. Manufactured to exact Caterpillar specifications, it provides a durable, wear-resistant surface crucial for maintaining compression and sealing, unlike a scored or worn liner that compromises engine performance. Operators may notice a decrease in engine power, increased oil consumption, or blue smoke from the exhaust when this component begins to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing cylinder liner may initially cause increased blow-by, indicated by excessive crankcase pressure. If left unaddressed, oil consumption will rise, and the engine may exhibit a loss of power and rough running due to poor compression. Continued operation can lead to piston seizure and severe engine damage.

Installation Tip

Ensure the cylinder block deck surface is perfectly clean and flat before installing the liner. Never reuse old O-rings or seals; always install new ones to ensure proper sealing.

Service Note

Always replace piston rings when installing new cylinder liners, and inspect pistons for signs of wear or damage.
