Causes: Too much pump oil. The exhaust filter is installed incorrectly or the filter material is broken. The exhaust filter is blocked. Failure of the oil return valve and blockage of the return pipe. Check blog post for solutions.
Causes: The ambient temperature or suction temperature is too high. There is not enough air to ventilate the cooling pump. Too much oil in the pump. Insufficient pump oil. Oil deterioration. The exhaust filter is polluted.
Causes: The pump is working without oil or the vane is broken. Running under wrong rotation direction for a long time. The sliding bearing is seized or the shaft copper sleeve is cracked when working with little or no oil for a long time. Check blog post for details.
Causes: Oil deterioration. The exhaust filter is blocked. The ambient temperature is lower than 5°C. Solution: Change new oil. Replace the exhaust filter. Increase the ambient temperature.
