FAQ

Q1: How do I confirm this piston fits my Komatsu S4D105 engine?
A: To ensure a proper fit, please cross-reference your engine’s serial number with the model designation (S4D105-5A or S4D105-5B) and verify the part number 6137-32-2110 on your existing piston or your equipment’s parts manual. This piston is manufactured to OEM size standards for these specific engine models.

Q2: What is included in the assembly, and can I use my old piston rings?
A: This product includes the piston and the piston pin. We strongly recommend replacing the piston rings and cylinder liners at the same time to ensure a proper seal and prevent premature wear. Using old rings with a new piston can compromise compression and oil control.

Q3: What is the recommended installation procedure for this piston?
A: Installation should be performed by a qualified diesel mechanic. Key steps include cleaning the cylinder bore, lubricating the piston and rings with clean engine oil, using a proper ring compressor, and torquing the connecting rod bolts to the manufacturer’s specifications. Always follow the Komatsu service manual for your specific engine model.
