Faults and troubleshooting
Fault Failure Cause Troubleshooting

Insufficient or no oil flow

Suction oil filter resistance larger population, or even blocked Cleaning filter to reduce inhalation resistance
Suction pipe leaks or low oil level Eliminate leakage causes, heightening the oil surface
Overheat Cooling oil
Wear Parts Replacement of worn parts
Reverse operation of pump Correct turn
Key is cut Renewal key
Pressure or no pressure fluctuations Hydraulic system pressure valve does not work Pressure valve replacement
System with air Exclude air
Inadequate inhalation Suction oil filter diameter or greater
Suction pipe connection bolts loose Tighten suction tube with bolts
Damage pump parts Replacement of defective parts
Noise is too large Inhaled too much resistance, inadequate inhalation Suction oil filter diameter or greater
Pump body with airPump body with air If you drive, work in the oil pump body is filled
Cover before and after the "0-ring" or the front cover oil seal damaged Replacement of defective parts
Pump installation rack loose Solid compact rack
Installation of the coaxial pump, verticality tolerance, so that spindle by the radial force Re-install more positive concentricity, perpendicularity
Severe bearing wear Replacement
Oil viscosity too high Appropriate choice of oil
Oil temperature rises rapidly Large oil tank foam Elimination of intake because
Oil tank capacity cooling effect is too small or too bad Increased fuel tank capacity, improved cooling
Damage pump parts Replacement of defective parts
Pump oil spill Oil viscosity too low Appropriate choice of oil
Cover before and after the "0-ring" or the front cover oil seal damaged Replacement of defective parts
Hole to plug the pump back on Cleaning pump back hole
Installation of the coaxial pump, verticality tolerance. To spindle by the radial force Re-install the correct concentricity, perpendicularity
