173F Connecting Rod: The "Heavy-load Transmission Pillar" of 173F Heavy Diesel Engines

The 173F Connecting Rod is the "heavy-load transmission pillar" of 173F heavy diesel engines, designed for power transfer under extreme loads. Its body is made of ultra-high-strength forged alloy steel, with a yield strength of 900MPa after quenching and tempering—60% better fatigue resistance than ordinary forged steel, able to withstand high-frequency piston impact without deformation.

The bimetallic bearing liners at both ends have a steel back and friction-reducing alloy inner layer, with a friction coefficient of only 0.04 against the piston pin and crankshaft, no ablation even during short-term oil-free operation; the cold-pressed interference fit between the liner and rod hole avoids liner loosening under heavy loads.

Old rods often have "transmission jamming" and "power attenuation" due to insufficient material strength and liner wear. After replacing with the 173F Connecting Rod, engine torque output stability increases by 25%, and component service life extends to over 1800 hours.

Whether for continuous operation of large generators or high-load pumping of heavy water pumps, the 173F Connecting Rod supports power transfer under heavy loads with "high toughness + low wear + stable transmission" performance, being the core transmission component for reliable operation of 173F heavy equipment.
