6D95 Piston Ring 6209-31-2400 6136-31-2010 6136-31-2030 for Komatsu PC200-5 PC200-6 Excavator

Product Details

Product Overview

This high-quality piston ring set is engineered for Komatsu 6D95 diesel engines, commonly used in PC200-5 and PC200-6 excavators. The set includes the critical part numbers 6209-31-2400, 6136-31-2010, and 6136-31-2030, ensuring a precise match for your engine rebuild or replacement needs. Manufactured to OEM specifications, these rings are designed to restore compression, reduce oil consumption, and extend engine life in demanding construction and earthmoving applications.

Each ring in this set is precision-machined from durable materials to withstand the high temperatures and pressures of diesel combustion. Whether you are servicing a single excavator or managing a fleet, this piston ring set provides the reliability and performance required for continuous operation in tough job site conditions. The components are carefully packaged to prevent damage during transit and storage.

Key Features & Benefits

• OEM Specification Fitment: Manufactured to match original Komatsu dimensions and tolerances for the 6D95 engine, ensuring a direct replacement without modification.
• Durable Material Construction: Made from high-strength alloy cast iron with advanced wear-resistant coatings to minimize cylinder bore wear and extend service intervals.
• Optimized Oil Control: Designed with specific oil ring geometry to reduce oil consumption and prevent carbon buildup, maintaining cleaner combustion.
• Enhanced Compression Seal: Proper ring tension and profile ensure a tight seal against the cylinder wall, maximizing power output and fuel efficiency.
• Comprehensive Set: Includes all necessary rings (compression and oil control) for a complete piston assembly, eliminating the need to source individual components.
• Rigorous Quality Control: Each batch undergoes dimensional inspection and material verification to ensure consistent performance across all units.

FAQ

Q: How do I confirm these rings fit my specific Komatsu PC200-6 engine?
A: First, verify your engine model is a 6D95 by checking the data plate on the engine block. Second, compare your old piston ring part numbers with the numbers listed (6209-31-2400, 6136-31-2010, 6136-31-2030). If you have a different piston part number, please contact us with your engine serial number for cross-reference assistance.

Q: Can I install these piston rings without removing the engine from the excavator?
A: While technically possible in some cases, we strongly recommend removing the cylinder head and oil pan in a clean workshop environment. Proper cylinder bore honing and ring end-gap measurement are critical for a successful rebuild. Always follow the Komatsu service manual for your specific model. If you are not experienced with diesel engine rebuilding, professional installation is advised.

Q: What is the recommended break-in procedure after installing new piston rings?
A: After installation, run the engine at low idle (1000-1200 RPM) for 5-10 minutes without load to allow the rings to seat. Avoid prolonged idling. Then, operate the excavator under light to moderate load for the first 10-20 hours, varying the engine speed but avoiding full throttle or sustained heavy loads. Change the engine oil and filter after this initial break-in period to remove any metal particles from the seating process.
