178F Connecting Rod: The "Medium-load Transmission Link" of 178F Diesel Engines

The 178F Connecting Rod is the "medium-load transmission link" of 178F diesel engines, designed for power transfer in medium-heavy operations. Its body is high-toughness forged carbon steel, with impact toughness of 80J/cm² after normalizing—40% better fracture resistance than ordinary carbon steel rods, withstanding high-frequency piston impact without deformation.

The bimetallic self-lubricating bushings at both ends have a steel back and copper-based friction-reducing alloy inner layer, with a built-in lubricating layer—avoiding dry friction damage even with short-term insufficient lubrication; the interference fit precision between the bushing and rod hole is 0.01mm, eliminating the risk of bushing loosening during operation.

Old rods often have "transmission noise" and "power loss" due to insufficient material toughness and bushing wear. After replacing with the 178F Connecting Rod, engine power transmission loss decreases by 25%, operation smoothness increases by 30%, adapting to continuous medium-load operation of water pumps and generators.

Whether for farm irrigation machinery or small construction site power equipment, the 178F Connecting Rod supports power transfer under medium-heavy loads with "high toughness & impact resistance + self-lubrication & wear reduction + precision fit & stable transmission" performance, being the core transmission component for reliable operation of 178F equipment.
