Massey Ferguson 245 hydraulics issue

[BukitCase]

You're welcome; I finally got around to watching your video, and I'm worried that if you ever DO get some pressure in your system you may end up hurt or dead

Correct me if I'm wrong, but several of your fittings look like common black pipe fittings - if so, those are NOT pressure rated anywhere near the capability of your pump, and if they split open in the wrong place they can blind you, inject you with hydraulic fluid, or worse.

Also, it's hard to tell as short as the video is, but I'm seeing 'WAY more TEES than I would expect in a FUNCTIONING hydraulic system - normally, the ONLY place it's OK to tee a system is where a single valve is operating TWO lift cylinders, or two curl cylinders (not yours, it's a single curl system) - other than that, it's USUALLY OK to tee NON pressure returns to Tank, but NOWHERE ELSE.

If possible, it would really help us help you if you can draw a diagram of EXACTLY what is connected to what (BEFORE you spend any more $$) - with any luck, one of us might see where you're going wrong. And PLEASE, if I'm right about those iron pipe fittings, STOP - the ONLY part of a hydraulic system you MIGHT get away with that is the part that NEVER sees more than a couple hundred pounds of pressure (Tank returns)

If you're not used to drawing on the computer, you can do it in "amish CAD", aka pen and paper; then take as sharp a picture of that paper as you can, and post THAT here (click the "advanced" button, scroll down a bit and click on "manage attachments", then click "Add files", and follow the prompts.

Hang in there, eventually you'll get there... Steve

I hope I got it until loaded. Yes I removed some of the tees. That was part of my problem was I had to many spools. After removal of the other spools things started working or at least trying to work.

Yay it uploaded, lol. Anyway, yes I am in the process of replacing the wrong fittings. Also there are only two tees now where the two cylinders connect together and then run up to the valve. Thanks again for the help. I’m really hoping that this evening after we set the proper torque on the load check valve things will start working properly.

 

[Subn3r0]

Can you answer if the load check valve not being at the proper torque would cause the symptoms I am experiencing?

 

[BukitCase]

That drawing looks a LOT better than what I THINK I saw in the vid; as to the relief, I've not used that particular valve with an ADJUSTABLE relief but either type only needs to move the spring a SMALL amount to change pressure - so, depending on how loose yours WAS, it could conceivably lower your pressure at the cylinders to just enough to move things empty/without the actual bucket - the shim washers on the so-called "fixed" reliefs are usually only .020" to .040", so loosening a screw-adjust version even 1 turn might do what you saw.

I'm a firm believer in the old Army mantra, "the map is NOT the terrain" (even if it IS a topographical map :laughing: ) so, my take is to try it and see... Steve

 

[BukitCase]

Oops, if you actually mean the load check valve and NOT the RELIEF valve, I'd hafta say "maybe"... Steve

 

[BukitCase]

Also, is that Gresen valve the FIRST thing your pump's pressure output sees? Where's your 3PH tie into that?

 

[Subn3r0]

Hey thanks again for the input. Yes I am hoping that is the issue since I took it all the way out, not understanding what it was and what I was doing. Will know in about an hour. Yes the valve is the first inline. My manifold or bypass diverts the power from the 3pt to the valve. After I looked at the pdf I realized what I had done.

 

[BukitCase]

If you aren't tired of "enjoying" your hydraulic "ejumakashun", a $20 part (that you may already have) and a bit more plumbing (likely hard lines) will let you discard (or re-direct to another use) that diverter, and have INSTANT use of loader AND the 3PH by just grabbing their levers (no switching necessary)

The $20 part is the PB sleeve (check that PDF) then look at your loader valve and see if that port is plugged, filled, or ??

It looked like your 3PH may already be fed with a hose; if so, eliminating the diverter might be even easier... Steve

 

[Subn3r0]

My loader valve does have pb unfortunately. So we took the relief valve apart and discovered the spring was broken. Also during the torque process the check valve was accidentally broken. So now I know what parts I need to order. Do you know where I can order parts?
