I have recently changed the control valve, o rings, washers, main piston rings, pump rings in the hydraulic system.I did not change or repaired the valve chamber.

When I tested it, it runs perfectly well in draft mode as well as position control mode but it instantly drop when I shut off the engine.

Do you think the valve chamber is the problem or there is some problem in the control valve installation.
 
What I would do is drain some the oil out so the pto lever side plate can be taken off. Then look around inside while someone else works the hydraulics. Since it leaks down rapidly when the engine is cut off you should be able to see where your problem is.
 
I have done that. There is no leak elsewhere which I can see. I have also tested the main piston separately and its not leaking. I am wondering if the worn out valve chamber will lead to leak and rapid fall
