This piston ring set seals the gap between the piston and the cylinder wall in the engine of the host tractor. Its primary function is to contain combustion pressure within the cylinder and to control oil consumption by scraping excess lubricant from the cylinder wall. A worn or broken ring set allows blow-by of combustion gases into the crankcase, reducing engine power and increasing oil consumption. This original assembly is manufactured to the same material and profile specifications as the rings originally installed in the engine, which maintains the correct ring-to-groove clearance and axial tension required for proper sealing. On installation, ensure the ring gaps are staggered around the piston and that the rings are compressed evenly during insertion to avoid breakage.
