FAQ
Q1: Is this piston a direct fit for my Mitsubishi 4M50 engine? A: Yes, this piston (ME224532) is the OEM standard size for the 4M50 engine. It includes the wrist pin and circlips. However, you must measure your cylinder bore to confirm it is within standard spec and has not been previously oversized.
Q2: Does this set include piston rings? A: No, this listing is for the piston with pin only. Piston rings are sold separately. We recommend ordering a complete ring set (part number ME224536 or equivalent) to ensure proper sealing.
Q3: What maintenance steps should I take during installation? A: Ensure the cylinder bore is clean and free of ridges. Lubricate the piston and rings with clean engine oil during assembly. Always use a piston ring compressor and avoid forcing the piston. New connecting rod bolts are recommended. After installation, follow the factory torque specifications for the con rod cap.
