Our commitment to quality ensures you receive a reliable product:
Q1: Is the 4923745 piston a direct fit for my Cummins ISX15 CM2350 engine?
A: Yes, this piston is designed as a direct replacement for the ISX15 CM2350 and CM2250 engine platforms. However, we always recommend verifying your engine’s serial number and current piston part number to ensure compatibility with the specific piston crown height and bowl design required for your application.
Q2: Do I need to replace the piston rings and liners at the same time?
A: It is highly recommended to replace the piston rings and cylinder liners simultaneously with the pistons. This ensures a proper break-in period and prevents premature wear. For best results, consider our matching piston ring and liner sets.
Q3: What is the typical 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 skirt and rings, using a proper ring compressor, and carefully tapping the piston into the liner. Torque the connecting rod bolts to the manufacturer’s specifications. Always consult the Cummins service manual for your specific engine model.
