FAQ

Q1: Is this piston set a direct fit for my Komatsu PC120-2 excavator?
A: Yes, this piston set (OEM 6137-32-2110) is designed to directly replace the original pistons in Komatsu PC120-2 excavators equipped with the S6D105 engine. We recommend verifying your engine serial number to ensure compatibility with the S4D105 or S6D105 series.

Q2: What is the recommended installation procedure for these pistons?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: clean the cylinder bore thoroughly, lubricate the piston and rings with clean engine oil, use a ring compressor to install the piston assembly, and torque the connecting rod bolts to Komatsu specifications. Always consult the service manual for your specific engine model.

Q3: How do I maintain these pistons for optimal performance?
A: Regular maintenance includes using high-quality engine oil and filters, monitoring compression levels during tune-ups, and inspecting pistons during major overhauls. Avoid prolonged idling and ensure the cooling system is functioning properly to prevent overheating, which can damage piston rings and skirts.
