Faulty hydraulic main pump separation plates cause severe internal oil bypass, killing system pressure and stalling excavator operations. Weak divider plates deform under heavy cyclical loads, leading to extreme pump cavitation and expensive final motor rebuilds. B2B buyers cannot afford costly project downtime.
