Got the 300u going, but...

Posted by JayWalt on February 11, 2007 at 19:30:32 from (70.226.20.153):

I got her all going today. I am in the process of bleeding the air out of the system. The system is FULL of air, as the cylinders and hoses were emptied as well as most everything else to ensure only clean fluid is in the system. The filter seems to be doing well in its new spot. The fear I had of the front axle hitting it is no concern whatsoever. Now I have a question. The safety regulator directs flow to the res when no valves are being used. Now heres the thing, when i run her, about every 5 econds the pump seems to dead head and stop "deadheading" real quick, like not even a second, then its like a cycle. I thought that maybe there was an air leak in the suction line and the pump was going into captivation. Well, Its ovbious the pump is being deadheaded, because the high pressure hardline , you can feel it like its lifting a load when it "deadheads".
Now I had the safety regulator apart when I was inspecting, cleaning, regasketing the system, and there has got to be air in that bugger. I'm thinking/hoping that it will go away when the air gets bled out of it, and it seems to be less frequent, with period of nothing. I ran out of fluid to keep her filled up, so I had to stop for today, maybe tomorrow. Is this a plausible reason? Do I need to re-evaluate the safety regulator? Its got to be in there, but could somthing be stuck in there? I'd just like to get the thread going so I can get some resposnes for tomorrow. It's why I wish the site had a chat, u could go in and ask a few questions and hopefully someone will be there to help, instead of waiting til the last second, having a question, and having to wait multiple hours for responses, not that I dont appreciate the forum, cause I do. I think most of you understand what I mean.
Thanks guys!!

I'm still kinda lost as to how the safety regulator detects the valve needs a fluid pressure? I dont know why the valves just dont manually dump the fluid into the res. I mean let's say that you move the valve, there is no pressure going to the valve, so the valve cannot feed pressure to the safety regualtor to open a multipling valve of some sort hence feeding pressure to the valve. I have had it apart, but didnt investigate too deeply into how it works, its hard to follow the passages in the main assembly. I also couldnt get it totally apart, as I didnt have a spanner socket to remove the innards.
