Leaking Chief/Bailey's 3 spool valve - how hard to fix?

[FTG-05]

Why can't I find a parts/assembly diagram like this for Chief hydraulic valves? See the first 20 seconds of this video: YouTube

I wrote Bailey's and all they had was a dimensional diagram, that showed nothing of the internal parts. I can find no technical drawings or parts list on their web site. I google Chief valves but I can't find the manufacturer.

This is the valve I'm looking for: CHIEF G Series: 1 GPM, SAE 1 Inlet/Outlet, 3 Spool, 3625 PSI, 15-3625 PSI Relief Setting, SAE 8 Work Ports, 22959

Can anyone help?

Thanks,

Looks like those valves are just rebranded valves from Badestnost, a very well known manufacturer used widely here in Europe.

Specifically their P40 valves.

EDIT: It does say P40 on the description of the Chief valve.

Ok, I contacted Badestnost and asked for a parts list and disassembly diagram (in English). We'll see what they send me.

Thanks,

Once you find the right O ring dimensions I would just buy a whole kit that size. I did this about 2 yrs ago and bought a kit for about $16 with around 100 O rings. I cant tell you how many times I go hunting for an O ring now and find it in my kit.

However there can be some oddball hydraulic O rings. I wouldnt buy a kit for them.

One thing I remembered, is that since it's possible that it's a Badestnost valve, the O-rings will most likely be Metric. I think that can be part of the reason why you can't find the right ones.

I believe I had downloaded some literature from Badestnost since I have lots of valves from them and it's a good thing to have. I'll search for those later on.

Thanks guys: I'm gonna need it!!!

Got it hot today, working on my one mile gravel road. It's still leaking, albeit not quite as fast.

But drip......drip....drip......drip.

I'm still very suspicious that you have a internal crack on the valve body. It's would be hard to see, even with the valve all taken apart but that would be my guess.

The O-rings are meant to seal the slightest film of oil that can get past the spool and to prevent from outside contaminants to get in.

I thought I had a more detailed brochure for these valves but all I have is this: http://hydraulic-vlv.com/files/mf/products/12_file.pdf

Do you have a hydraulic shop nearby? Maybe they could test the valve for you.

There is a cylinder repair/rebuild shop nearby. I'll call them tomorrow and see if they are able to repair/rebuild 3 spool Bulgarian valves.

Thanks!

ETA: I pulled that same .pdf off the Bad site yesterday. Page 5/8 has some internal drawings, but not parts list. Thanks,

Keep us updated. I can't remember anything else to help you figure this out.

I've been thinking about this most of the day and I've suggested everything I know by looking at it from 4000 miles away.

Thanks, I appreciate the help very much. I'm beginning to think it's time to cut my loss:

Order this same valve from Bailey's or order something else from someone else?
