FAQ
Q: How do I confirm this piston is the correct part for my MAN engine?
A: The most reliable method is to cross-reference the part number stamped on your original piston or listed in your engine’s service manual with the OEM numbers provided in the “OEM Cross-Reference” section above (51.02501-7621, 51.02501-7602, 51.02501-7556). Always check your engine’s model and serial number plate.
Q: Is this piston sold as a single unit or as a set?
A> This listing is for a single piston assembly, which typically includes the piston body, wrist pin, and piston rings. For a full engine rebuild, a set of six pistons (for the D2866 inline-6 engine) is required. Please contact our sales team for set pricing and availability.
Q: What are the recommended installation procedures?
A> Professional installation by a qualified technician is strongly recommended. Critical steps include: thoroughly cleaning the cylinder liner, checking ring end-gap, properly lubricating the pin and rings, and ensuring correct ring orientation. Always follow the official MAN engine workshop manual procedures for torque specifications and assembly sequence.
