This connecting rod assembly is engineered as a direct replacement for Yanmar 3TNA72 series diesel engines. The component features a center-to-center distance of 112.00 mm and a piston pin bore diameter of 21 mm, matching the original equipment specifications for the 72 mm bore, 3-cylinder engine platform. Manufactured from forged steel for high tensile strength and fatigue resistance, the rod undergoes precision machining to ensure exact fitment on the crankshaft journal and piston pin. The part is compatible with Yanmar engine variants 3TNA72, 3TNA72E, 3TNA72L, 3TNA72U, 3TNA72UJ, 3TNE72, 3TNA74, and 3TNE68. Primary applications include John Deere F925, 430, 455, 670, 755 front mowers, Kobelco SK15SR mini excavators, Takeuchi TB015 excavators, and Thermo King TK3.95 refrigeration units.
