FAQ

Q1: Is this piston a direct fit for my Cummins 6CT engine?

Yes, part number 3926963 is a direct OEM replacement for the Cummins 6CT and 6D114 series. However, we strongly recommend verifying the part number against your engine’s serial number to ensure compatibility with the specific piston design (e.g., articulation, cooling gallery type).

Q2: What is the standard piston ring set I should use with this piston?

This piston is designed to work with a standard 3-ring set (compression, intermediate, and oil control). For optimal performance, we recommend using a matched ring set designed for the 6CT/6D114 engine. Please check your engine manual for the correct ring groove dimensions and gap specifications.

Q3: What are the critical installation steps for this piston?

Installation should be performed by a qualified technician. Critical steps include: 1) Thoroughly cleaning the cylinder bore. 2) Installing the piston rings with proper orientation (ring gap position). 3) Lubricating the piston skirt and rings with clean engine oil. 4) Using a proper ring compressor to avoid ring breakage during installation. 5) Torquing the connecting rod bolts to the manufacturer’s specifications.
