1800A hydrolic pressure

having problem with the remote cylinders couplers... one way you move the lever you have good 1200 psi and it lifts the implement..move the lever the other way it is very slow..no power low psi 500 psi.. if that....this is the same on both left and right sides couplers..
 
You have an internal leak and if you have 1200 pounds on one end and 500 on the other end I would say your leak is in the top cover. That will make it easy to repair. More questions? J
 
You need to check the bypass valve that is used for single acting cylinders and see if it is open. On the left side it is behind the flow control and in front on the right side. they are to be opened three turns for single acting and turned all the way in for double acting. the 500 hundred PSI sounds about right for the pilot pressure needed to open the PO check that acts as the load holding valve so a single acting cylinder can be lowered.
 
Hart-Parr 70.... YOU WERE RIGHT....the set screws was 3 turns out and in single action cylinder possion...i screw it in and now she works good...Thanks
