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.
