FAQ

Q: Is this piston liner kit a direct fit for my Komatsu PC60-7 excavator?
A: Yes, this kit (OEM 1K75526/000) is specifically designed for the Komatsu S4D95 engine found in the PC60-7 model. However, we strongly recommend checking your engine serial number and comparing it to the existing piston assembly to ensure it matches the exact variant, as minor design changes may have occurred over different production years.

Q: What does the kit include? Do I need to buy any additional parts?
A: The kit includes the piston, cylinder liner, and a full set of piston rings (compression and oil rings). For a complete engine overhaul, you may also need to purchase connecting rod bearings, main bearings, head gasket set, and oil seals separately, as these are not included in this specific kit.

Q: How do I properly install a new piston and liner set?
A: Installation should only be performed by a qualified diesel mechanic. Key steps include: cleaning the cylinder block bore, pressing in the new liner with the correct interference fit, ensuring the liner protrusion is within spec, assembling the piston rings staggered, and lubricating all components with clean engine oil before installation. Always refer to the official Komatsu service manual for torque specifications and procedures.
