Yes, this part number (6128-31-2070) is specifically designed for the Komatsu 6D155 engine family, which often includes the S6D155 variant. However, we always recommend checking the engine serial number and comparing the old ring dimensions (thickness and width) to ensure a perfect fit.
For optimal performance and longevity, it is highly recommended to replace the piston rings in conjunction with new cylinder liners. Reusing worn liners with new rings can lead to poor sealing and accelerated ring wear. If the liners are still within specification, a light hone of the cylinder wall is required before installing new rings.
Installation should follow the standard Komatsu service manual. Key steps include: 1) Lubricate the rings and cylinder bore with clean engine oil. 2) Use a piston ring compressor to compress the rings evenly. 3) Ensure ring gaps are staggered (typically 120° apart) and do not align with the piston pin bore. 4) Ensure the oil ring expander ends do not overlap. Improper installation can cause ring breakage or engine failure.
