The 080V02511-0721 Piston is a precision-engineered component designed for the Sinotruk T5G series, specifically optimized for the MAN MC07 engine platform. As a fundamental part of your howo truck parts supply chain, this piston is built to handle the rigorous demands of high-torque, heavy-duty commercial transport.
Constructed from advanced high-silicon aluminum alloy, this piston offers exceptional thermal conductivity and low thermal expansion. This ensures that even under the extreme pressures of a turbocharged MC07 engine, the piston maintains its structural integrity and optimal clearance within the cylinder liner.

Guidelines for Installing the 080V02511-0721 Piston:
-
Inspection: Before installation, verify that the piston crown is free of nicks and the ring grooves are perfectly clean. Check the part number 080V02511-0721 against your engine manual.
-
Directional Alignment: Most Sinotruk pistons feature an arrow or “Front” mark on the crown. Ensure this arrow points toward the engine’s timing gear (front) to align with the offset of the piston pin.
-
Connecting Rod Assembly: When pressing the piston pin, ensure the connecting rod is oriented correctly. Use the specified circlips and ensure they are fully seated in their grooves.
-
Lubrication: Apply a generous layer of clean engine oil to the piston skirt, the pin, and the cylinder walls.
-
Ring Alignment: If you are also installing rings, ensure the gaps are staggered at 120-degree intervals and do not align with the thrust face of the piston.
-
Insertion: Use a high-quality piston ring compressor. Gently tap the piston into the cylinder bore using a wooden or plastic hammer handle, ensuring no resistance is felt from ring misalignment.
