Take it nice and slow, draw things up as you dissemble, take pictures , identify nuts , bolts, screws where they go perhaps by poking holes on a card board the same pattern and place the screws in appropriate holes. It take a bit of a time but end result would be much better. If I turned wrench to make a living probably I would not do what I suggests. I really like small magnetic SS trays you can buy from HF. I just try to keep things organized so if nothing else I can put them back together like how I found them originally.

I removed the valve assy and removed the top valve where you have circled. I think that might be the unload valve. When I blew air in to the inlet port, air came out. when I put it back together air wouldn't come out any more. This eve. I put the assy. back on the tr. to try it and it worked. All you really have to do is clean everything in the assy. and change the oil. It will probably work.

Can you identify the part # per diagram I gave you? can you post a picture of partial dis assembly and point on the part. Metal part can not be damaged by penetrating oil but o-ring can be damaged. I use a bit of oil and let it soak. perhaps I put a bit of heat (very little) and use a small mallet with plastic head and try to tap the valve out. whatever you do, do as gently as you can. Make sure not scratch the spool and metal part as they will be ruined for good. if you need to take the rust off use finest emery cloth a nsome oil to remove rust on internal parts. Try some compressed oil if you can.

The valve at the top of the assy is held in with a plug and spring. it should slip out. I have stuck snap ring pliers in to grab the inside of the valve (the kind you squeeze to open snap rings) and try to turn and pull on it. Just keep spraying penetrating oil.

What happened to detailed pics and dis assembly pics and details.
Can't just seek an "answer" without giving more details, it is difficult and time consuming to just guess an answer. How you did the repairs and your feedback is essential so "educated guess" can be dispensed.

You need to monitor pressure with an oil filled gauge to get some clues. Need to be more descriptive. What does lowering and raising functions with or without load on 3 point arm.
