20820363 — 6 Pcs Piston Rings 20820363 For Volvo D12D Lde3 L150E Ec330B Ec330C Ec360B Ec360C Ec360Chr

These piston rings are essential for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. Manufactured from high-strength cast iron with a wear-resistant coating, they maintain a tight seal, unlike worn rings that allow combustion gases to blow by and oil to enter the combustion chamber. Operators may observe increased oil consumption, blue exhaust smoke, and a loss of engine compression when piston rings 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

Increased blue smoke from the exhaust and a noticeable rise in oil consumption are common initial indicators of worn piston rings. Continued operation can lead to a significant loss of engine power and compression, potentially causing overheating and internal engine damage.

Installation Tip

Thoroughly clean the piston ring grooves to remove all carbon deposits before installing the new rings. Never force the rings into the grooves, as this can cause them to break or become distorted.

Service Note

When replacing piston rings, it is essential to inspect the cylinder walls for wear or scoring and check the pistons for any cracks or damage.
