Zs1125 Connecting Rod for Agricultural Single Cylinder Diesel Engine

Cast connecting rods have low cost and average toughness, with internal defects such as porosity and air holes, only suitable for low-speed and light-load ordinary equipment. Forged connecting rods are formed by high-temperature forging with higher material density and no internal defects, featuring greatly improved strength, fatigue resistance and impact resistance, applicable to high-speed, heavy-load and long-term continuous working conditions. Precision forged connecting rods are preferred

Common causes include connecting rod wear and deformation, excessive bushing clearance, loose bolts, fatigue damage and assembly deviation. Slight abnormal noise can be solved by tightening bolts and calibrating assembly position; continuous jitter, metal impact sound and power attenuation indicate irreversible wear or deformation of the connecting rod, which requires timely replacement to avoid cylinder block scratch, crankshaft damage and greater equipment failure and maintenance losses.

Forged connecting rods can be used stably for a long time under normal light-load working conditions; the service life decreases with the load intensity under high-frequency heavy-load and high-speed conditions. Daily maintenance such as regular oil replacement, avoiding long-term equipment overload operation, timely inspection of loose accessories and standardized start-stop operation can effectively reduce connecting rod impact wear and greatly extend service life.
