1101337 Kit-Piston Ring — Cat 3408

This piston ring kit is engineered to seal the combustion chamber in your engine, preventing gas leakage and controlling oil consumption. Manufactured to precise standards, it ensures optimal compression and engine efficiency, unlike worn rings that allow blow-by and oil burning. Operators may notice increased exhaust smoke, a drop in engine power, and elevated oil usage when this kit begins to fail.

Installation & Application Notes

Always match seal material to fluid type — NBR for petroleum, FKM (Viton) for high-temperature/chemical applications. Lubricate seals with clean fluid before fitting — never grease. Check shaft surface for scoring — rough surfaces destroy new seals within hours.

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

Failure Symptoms

Initial symptoms of a worn piston ring kit include a slight increase in blue exhaust smoke and a subtle decrease in engine power. If ignored, this will progress to significant oil consumption and a noticeable reduction in overall engine performance. Continued operation can lead to accelerated wear on cylinder liners and pistons.

Installation Tip

Thoroughly clean the piston ring grooves, ensuring no carbon deposits remain before installing the new rings. Pay close attention to the correct orientation and end gap of each ring as specified in the service manual.

Service Note

Inspect cylinder liners for wear and damage, and check the condition of the pistons during piston ring replacement.
