3919937 — Cylinder Liner 3919937 For Cummins Engine 6C8.3 Isc Cm554 Volvo Excavator Ec240

This cylinder liner forms the inner wall of the engine cylinder, providing a smooth surface for the piston to reciprocate against. It is manufactured to precise dimensions and material hardness standards, ensuring optimal sealing and minimal friction compared to a worn liner with scoring or ovality. Operators may notice increased oil consumption, blow-by, or a decrease in engine compression if this liner is damaged or worn.

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

Early signs of cylinder liner wear include increased blue smoke from the exhaust due to oil burning and a noticeable loss of engine power. If left unaddressed, this can lead to severe blow-by, reduced compression, and potential piston or ring seizure, leading to significant engine damage.

Installation Tip

Ensure the cylinder block deck surface is perfectly clean and flat before installing the liner to achieve a proper seal. Avoid using excessive force when seating the liner, as this can damage the liner flange or the block.

Service Note

When replacing cylinder liners, always install new piston rings and inspect the pistons for wear or damage.
