71818 XCMG GR2605 motor grader breather plug
71818 breather plug is a special ventilation component used in closed cavities such as gearboxes, drive axles and hydraulic tanks of construction machinery. It mainly balances the pressure inside and outside the cavity to prevent oil leakage and seal damage caused by excessive internal pressure due to temperature rise during operation. It also blocks dust and moisture from entering to ensure stable pressure and internal cleanliness.
