Good Evening,
I have searched over these forums for the last couple days in search of a solution to my problem and have found nothing that quite works with what I am dealing with. I'll give a brief history and then explain my issues in as much detail as I can.
We bought the machine about 7 months ago from Richie Bros in Phoenix AZ. Towed it to Tucson AZ and used it for the last 7 months without fail. The Z45 is an amazing machine. About a month ago one of my crew members was using it to install lights in the top of our shop. He came down after about an hour in the air and mentioned to me that the platform would not rotate back to the left. He had moved the platform to the right and it would not go back. Along with that came the problem of the JIB not moving up. I then starter to TS the issue. I removed both hydraulic lines from the JIB and the Rotate cylinder and reversed them. I was able to move the platform back to center and have the JIB move up. Went back and changed the lines back to their original position.
From there we had a hydraulic hose company out building hoses for our shop and he mentioned that he has rebuilt the check valves on the Z45s plenty of times and offered to do so. He removed the check valve on the rotate cylinder and marked the hoses. Along with that he removed the JIB Boom Manifold to have it rebuild. He marked the hoses but not the wires. (Amateur mistake, sorry). He rebuilt both of the the parts and brought them back. We installed them and still, the same problem. Waste of a little bit of money but they gave a discount on the other hoses we bought.
Now, we removed the lines from the JIB Boom Manifold and checked pressure there. Line V2 checked at 3000 PSI while V1 checked at about 600 PSI. Not sure what the problem is there but I think it might be further up.
What I need help with? I need to know how to wire up the coils that attach to the JIB Boom Manifold. I have no idea what goes where. I also need to know what I should check earlier on in the system that could be causing the low pressure on the V1 line.
Thanks in advanced and I hope to get this solved. Please ask any questions you can and I'll respond as soon as I can.
