It is intended for use in engineering machinery engines, helping to restore compression, reduce oil consumption, and improve overall engine efficiency.
Key Features & Benefits
OEM-Grade Fitment: Directly replaces Komatsu part number 6209-31-2400, ensuring a perfect match for the S6D95 engine block without the need for modifications.
High-Quality Material: Constructed from durable alloy cast iron, providing excellent wear resistance and longevity under the high-stress conditions of heavy-duty excavator operation.
Optimized Oil Control: The 4.0mm oil ring effectively scrapes excess oil from the cylinder walls, minimizing oil consumption and preventing carbon buildup.

FAQ
Q: How do I confirm that this piston ring set fits my Komatsu S6D95 engine? A: First, verify your engine model number (S6D95 or 6D95) stamped on the engine data plate. Then, cross-reference your existing ring dimensions (2.5mm x 2.2mm x 4.0mm) with the specifications provided. The OEM number 6209-31-2400 is the primary identifier for this exact set.
Q: What is included in this set? Does it include rings for all 6 pistons? A: Yes, this set includes the top, second, and oil control rings for all six pistons of the S6D95 engine. The total weight of the package is 5 kg, which accounts for the full set of rings for a complete engine rebuild.
Q: Can these rings be installed without removing the engine from the excavator? A: While it is technically possible, we strongly recommend removing the cylinder head and the oil pan for a proper installation. The pistons must be removed from the block to clean the ring grooves and install the new rings correctly. This typically requires the engine to be in a service bay.
