Precaution of installing Power Steering Pump
Please pay attention to the following instructions during the Power Steering Pump installation,to avoid any loss.
1. To prevent any trash and metal chips inside hydraulic pipe flowed into the pump,thus oil leak,abnormal noise and turning hard happened,steering system hydraulic pipe wasted oil should be released and cleaned.
2. Before assembling the high pressure connector,enough fresh hydraulic oil should be poured into the pump from high pressure oil mouth to avoid non oil absorption in low speed,then install the high pressure pipe connector and other pipeline ,all the pipeline joint should be fixed tightly without loose or oil leaking hidden trouble.
3. Enough steering oil should be poured into the oil reservoir,start the engine,drive the steering pump in low speed,and make sure the whole steering system full with steering oil,meanwhile,the fluid level of oil reservoir will be dropped rapidly during the oil pouring,so continuous oil filling is required to prevent air absorption in the pump.
4. Turning the steering wheel from one limiting position to another limiting position,and repeat 10-15times.
Don\'t stop in the limiting position over 5 seconds.
Don\'t use over strength in the limiting position,otherwise the fluid stays foamy.
Repeat the above action,until no bubble leaked out.
5. In the process of installing pump transmission belt,tension force should be moderate,otherwise,abnormal abrasion & noise,premature damage,oil leakage & hard steering force will be shortly happened in case of too tight tension force.
6. All standard operation should be followed during the installing,hammer and other objects knocked is strictly forofferden.We are not responsible for any nonstandard installing damage,except the quality defect.
Note: Abnormal noise and reservoir oil foam will be happened during the trial run unless correct venting,because of remained air stayed in steering system,affer running 10-20kms,all the remained air will be released,and the noise will be disappeared.
FAQ
Q1 Q: Why is the pump making a whining noise all of the time?
Q1 A: A whining pump is usually caused by air in the system. Remove reservoir lid and inspect fluid level and condition. If fluid has foam or air bubbles present, you must bleed the system again. Some systems are very difficult to bleed manually and may require the use of a vacuum pump to extract all of the air from the system.
Q2 Q: Why do I still have hard steering in one direction after I replaced the pump?
Q2 A: The problem is not in the pump, it is in the steering gear. The pump would cause a steering problem in both directions.
Q3 Q: I bought a replacement power steering pump and my original pulley has a loose fit on the replacement pump shaft. What should I do?
Q3 A: The end of the original pump\'s input shaft enlarged causing the pulley hole to increase during removal. The pulley must be replaced.
Q4 Q: I only have assist when increasing engine rpm after installing the replacement pump. What\'s causing this?
Q4 A: Most likely cause is contamination. Remove the pressure hose and pressure fitting on the power steering pump. Remove the flow control valve and spring. Clean the valve and check the valve bore for damage. Reinstall the spring, valve, fitting and hose. Flush and bleed system and re-test. If okay, install power steering filter to prevent problem from re-occurring.
