Q1: Is this piston set compatible with the Komatsu PC130-8 or PC130-7 models?

A: Yes. The ring set (6276-31-2300) includes all necessary rings for a single piston: typically two compression rings and one oil control ring assembly. You will need to purchase the required number of sets based on your engine’s cylinder count (4 sets for a 4-cylinder engine).
Q3: What is the recommended installation procedure for these pistons?
A: We strongly recommend professional installation by a certified diesel mechanic. Key steps include: cleaning the cylinder bore, checking ring end gap, lubricating the piston and rings with clean engine oil, and using a proper ring compressor for installation. Torque the connecting rod bolts to the manufacturer’s specifications (usually 90-110 Nm for this engine, but please consult your service manual).
