FAQ

Q1: Is this piston a direct fit for my Mitsubishi 4M50 engine in a Caterpillar excavator?
A: Yes, the ME227603 piston is a standard direct replacement for the 4M50 engine. It is designed to match OEM dimensions exactly, so no modifications are needed. However, we recommend checking your engine serial number and existing piston part number to confirm compatibility, especially for older or modified units.

Q2: What is the recommended installation procedure for this piston?
A: We suggest having a qualified diesel mechanic perform the installation. Key steps include cleaning the cylinder bore, lubricating the piston and rings with clean engine oil, and using a ring compressor to install the assembly. Always torque the connecting rod bolts to the manufacturer’s specification (typically around 60-70 Nm for this engine).

Q3: Do you offer oversized pistons for rebored cylinders?
A: Currently, this listing is for the standard size (104mm) piston. If you require an oversized piston (e.g., 0.50mm or 1.00mm oversize), please contact our sales team. We may be able to source custom sizes based on your specific rebuild requirements.
