Crown Pressure Systems require very little maintenance, and the systems are accurate  +/- 2%. Each system consists of a 6″ gauge (CG602-CG603 Series) , gauge protector (gauge saver, 1:1 piston separator, 4:1 debooster), and hydraulic hose.  All  Crown systems are pre-charged with fluid and ready to use, and all the operator needs to do is install the system and adjust the sensitivity to get the most accurate readings.  Overtime, the pump pressure system may lose hydraulic fluid and need to be recharged.  Following the steps in this video will ensure that your pump pressure system provides the consistent readings and long life for the entire system.

 

 

 

Steps to Recharge a Pump Pressure System

Remember to check the following components to the left regularly: fluid levels; damper assembly and sensitivity; inspect gauge protector for cracks, cuts, dents, leaks; inspect hose connections; and inspect gauge for broken glass, loos pointers and loose knobs.
Step One: Remove the cap from check valve on the diaphragm protector.
Step Two: Attach aluminum hand pump to the check valve. Do not tighten swivel completely.
Step Three: Fill the hand pump reservoir with Crown’s red hydraulic fluid.
Step Four: Push on the hand pump plunger to move the hydraulic fluid towards the system. Air bubbles will emerge between the hand pump and check valve.
Step Five: Once you see a small amount of fluid coming out of the connection, completely tighten swivel to the check valve. There should be no bubbles coming out of the connection at this point.
Step Six: Remove the 1/8 pip plug in the gauge, making sure to tape the thread with Teflon tape.
Step Seven: Turn diaphragm protector upside down so that you can see the diaphragm.
Step Eight: Pump hydraulic fluid into the system until the rubber collapses its sides together approximately 38 PSI. The diaphragm sides will be just touching each other.
Step Nine: Remove the hand pump from the check valve.
Step Ten: Replace the check valve cap.
