Low lubricating oil pressure in the Stain high-speed pump?
The internal clearance is large, the oil temperature is high; the pump can adjust pressure but only to a low level; the oil is of incorrect type or poor quality; there is blockage or leakage at the inlet; the pressure gauge is faulty; and the mating surfaces between the main oil pump and the bearing housing are not level. . . . Wait
1. The oil filter needs to be replaced； 2. Oil leakage is occurring at the rubber seal in the internal oil circuit; the rubber seal needs to be replaced ； 3. The flat surface of the cycloidal oil pump is not in proper contact with the seat hole or is worn, resulting in the connection between the inlet and outlet of the cycloidal oil circuit ； 4. Insufficient spring force at the top of the cycloidal oil pump
