197-9322 Cylinder Liner — Cat C12 C15

This is a precision-machined cylinder liner that forms the inner wall of the engine cylinder, providing a sealing surface for the piston rings. It is made from high-strength, wear-resistant material to withstand the extreme pressures and temperatures of combustion. A worn or damaged liner can result in loss of compression, increased oil consumption, blue exhaust smoke, and a noticeable drop in engine power.

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

The first indication of a worn cylinder liner is often increased oil consumption and a slight loss of engine power. As wear progresses, you may notice blue smoke from the exhaust due to oil burning in the combustion chamber, and a significant reduction in compression. If left unaddressed, severe liner wear can lead to piston seizure and major engine damage.

Installation Tip

Ensure the cylinder block deck surface is perfectly clean and flat before installing the liners to guarantee a proper seal. Do not reuse old O-rings or seals; always install new ones with the liner.

Service Note

Inspect pistons and piston rings for wear or damage when replacing cylinder liners.
