Professional Installation Guide
Step-by-Step Installation for 080V02503-6810 Piston Rings:
-
Cylinder Preparation: Before installation, ensure the cylinder liner is clean and inspected for wear. Apply a light coat of engine oil to the cylinder walls.
-
Ring Gap Inspection: Place each ring into the cylinder bore and use the piston to square it up. Measure the end gap using a feeler gauge to ensure it meets Sinotruk MC07 technical manual standards.
-
Correct Orientation: Identify the “TOP” mark on each ring. Ensure the marked side faces the combustion chamber (upward).
-
Sequential Fitting: Use a professional piston ring expander tool to avoid snapping the rings. Install the oil control ring first, followed by the second compression ring, and finally the top compression ring.
-
Staggering the Gaps: Position the ring gaps at 120-degree intervals around the piston. Never align the gaps with the piston pin axis or with each other to prevent “blow-by.”
-
Lubrication: Thoroughly lubricate the entire assembly with clean engine oil before inserting the piston into the block using a ring compressor
