Review HARLEY DAVIDSON New Oem Bigtwin .040.s. Piston And Rings fits FLH 1955-73

Introducing the Harley-Davidson 22146-55B 1955-73 FLH Big Twin 040 O.S. Piston Rings, specifically engineered for Harley-Davidson Big Twin engines from the year 1955 to 1973. These piston rings are meticulously crafted to ensure optimal engine performance and longevity for your classic motorcycle.

The set includes four piston rings: the compression ring, the oil control ring, the skirt ring, and the top ring. Each ring is precision-manufactured to exacting specifications using high-quality materials. The compression ring, which sits at the top of the piston, is designed to seal the combustion chamber effectively, allowing for efficient transfer of power from the fuel to the crankshaft. The oil control ring, positioned below the compression ring, works to prevent oil from leaking past the piston and into the crankcase. The skirt ring, located at the bottom of the piston, is responsible for sealing the piston to the cylinder wall and preventing the loss of compression. Lastly, the top ring, which is the first ring in contact with the cylinder wall, provides a tight seal to prevent the loss of compression and ensure efficient combustion.

These piston rings are designed to fit Harley-Davidson FLH Big Twin engines with a bore size of 3.50 inches and a stroke length of 3.75 inches. The outer diameter of the rings ranges from 3.65 inches to 3.95 inches, depending on their specific function. Each ring is also heat-treated to ensure they can withstand the high temperatures generated during engine operation.

Installing these piston rings is a straightforward process, but it is recommended that the installation be performed by a professional mechanic to ensure proper fitment and seating. When replacing piston rings, it is also important to check the condition of the piston, cylinder wall, and other engine components to ensure a proper seal is achieved.

In summary, the Harley-Davidson 22146-55B 1955-73 FLH Big Twin 040 O.S. Piston Rings are essential components for maintaining the performance and longevity of your classic Harley-Davidson Big Twin engine. These high-quality piston rings are precisely manufactured to fit your engine and are designed to seal effectively, preventing oil leaks and ensuring efficient combustion.
