John Deere JD400 service manual

Try bending some coat hanger wire or something similar to catch a piece of that screen and pull it out.

Well, I may have screwed the pooch in this one. It's what I get for trying to work on hydraulics and knowing nothing about it. The plug I took out to get to the screen wasn't for the screen. I finally got what I thought was the screen out and it ended up being a valve. The best way to describe what came out was it was like a large version of a forward/reverse piston in an air impact gun. I put it back in but it had a key way or notches about mid way through and I'm not sure if I messed up whatever went in there. I THOUGHT I was going for sort of a cartridge screen type thing but stopped and thought about it and realized it was simply a tube screen and that it was right there where the house goes in. It is out and cleaned now but I think that may be useless now. The plug and valve I mistakenly took out is almost directly above the vertically mounted filter cartridge and is about 6" long. Any help or advice would be greatly appreciated!

Are you referring to valve(parts key 3)? That's the hyd filter relief valve. If so it needed to be removed also especially if it was stuck open.

Yes, I hadn't been back on the computer, only my phone, so I couldn't see the picture. It was the relief valve

Only the valve part came out nothing behind it. Thanks for the reply, I don't feel as bad now about possibly ruining the transmission

I would strongly suggest buying the service manual from John Deere. If you go online you can download it instantly in PDF format, or order in on CD, or order a paper manual.

Thanks for the help. I got it all back together and found the sectionals on JDparts. I'll order a manual later this week. Still have the same problem I had before I started. Blew another O ring out. Once I get the manual I'll try to tackle it again. Hard to even describe problem I'm having when I don't know the name of the part having the problem,lol
