What is the difference between the a blue/ white, blue, white, yellow , and green valve?
I remove the valve but the broken end is in the pump? It was stuck bad in the pump.
Help Please. thank you.

The valve should come out if you pull on it hard enough. There is a ball and detent spring that retains it in place.

The different colors of valves are for different oversizes of valves available for service if you have one that leaks too much internally.

Bern,

Would you happen to have one of those diagrams for a Ford 8210 hydraulic lift control. This system was unnecessarily complicated and the diagrams we have are almost useless. This is the one with the electronic lift control system called the EDC.

The documentation we got looks more like a patent application for a P.I.T.A. system that would take an electronic engineer to understand. I would also like to find out what the pulse modulation frequency is for this thing so I can make a test stand to check out the valve control. They call this a force motor.
 
Do you have the Ford service manual for that system, because if you do, then I won't be of much more help. The Ford manual has about a 20 page section on the 8210 EDC system, which includes a few diagrams, which I would be willing to scan for you and send via pdf if you send me your e-mail address.

You can either include your address directly here in a reply, or enable it in YT.
 
I will have to recheck the copies of material we have. What we were looking for is a color illustrated diagram like you posted for the 5000 pump, but we need as many illustrated diagrams mainly of the pump, plumbing, the edc valve and computer control system.

It appears a bubba disassembled the force motor not knowing that the washers were actually belville springs adding to a problem already present in the system. I think I have correctly reassembled the force motor, but need to see how the different safety checks are choreographed to make this ballet work.
 
I went to "preferences and set always show email address.

what else do I have to do. Is it broken like the editing function which has been broken for years?
 
I'm not sure what to suggest on the e-mail thing, other than to contact the forum managers. As for editing,
that never has been a feature here. Wish it was.
 
Editing was a feature a number of years ago, then it went wonky when the server? went down for several days or there was a system crash. When it came back up editing was temporarily disabled. If I am wrong I guess I will have to eat Corvus.
 
(quoted from post at 21:35:47 03/19/19) Editing was a feature a number of years ago, then it went wonky when the server? went down for several days or there was a system crash. When it came back up editing was temporarily disabled. If I am wrong I guess I will have to eat Corvus.

I complained to the admins about the lack of editing a while back and I received a response that it is an administrative choice based on a technical issue due to both classic and modern view being enabled, as each view stores the posts in a separate database, so when a new post is made in either view it gets stored in both databases, but if they were to allow editing it would only edit the post in the database for the view you are using when you edit it, so the databases would be come out of sync. So they decided that since some folks absolutely love classic view and would scream to high heaven if it were removed, and others feel the same way about modern view, that their only choice was to leave both views enabled and to disable editing.
