FAQ

Q1: How do I confirm this piston ring set will fit my Komatsu S4D95 engine?
A: Start by locating the engine model plate on your machine. Confirm the engine is an S4D95. Next, verify the OEM part number (6204-31-2203) on your existing piston ring set or your engine parts manual. This is the most reliable method to ensure a correct fit.

Q2: What is the recommended installation procedure for these piston rings?
A: Installation should be performed by a qualified diesel mechanic. Key steps include cleaning the ring grooves, checking ring end-gap in the cylinder bore, and using a piston ring compressor for installation. It is critical to stagger the ring gaps (typically 120 degrees apart) to prevent blow-by. Always refer to the official Komatsu service manual for your specific engine.
