Creepy loader

[Rail9222]

Cali is right. When the 3 point is down the float function works when the 3 point is up the fel creeps up rendering the float function useless.
I believe it is either the 3 point linkage or the valve having an internal leak. I just thought there might be something hereditary with it that I should look for.

that lock knob is huge and should be a CK-4150. It's really small . I think it's preventing your Neutral Pos. as you say. May not stop it all but slow the raise down I believe.

I'm confused....are you concerned with the 3pt creeping down or with the FEL arms creeping down? How are your hydraulics hooked up? Does the same pump drive both 3pt and FEL simultaneously? Some do...and some have a separate FEL pump and reservoir.

I ask because most older tractors will creep down, but it takes an hour or more for most to do that. It isn't something you can watch in a 5 minute video. I don't mind either end creeping down if they do it slowly because like I said....old tractors do that. But I do expect them to stay up for an hour or so when I'm doing chores.

You have that knob that will lock the 3pt hitch. Is it working?? It should hold up just about indefinitely when the knob is closed. If not, its probably the 3pt cylinder/piston/rings. Easy to fix on a Yanmar.

On the other hand it it is the FEL And if you need the front bucket to stay up - and the cylinders are rebuilt good as you say - then I would guess you could just put a similar on/off valve in the loader hydraulic line. I've never actually done that, but it ought to work.

What one usually does if the FEL loader still drops after a cylinder rebuild is to replace the loaders directional valve block complete. Surplus Hydraulics has them for a few hundred bucks.

I have never seen one of these YM's in person stay up for hours. 5 to 10 mins. Not hours. .....well a guy down the road from my farm had a 2210 I think it was and that would stay up forever, but that's the only one thinking out loud.

The knob is CK-4130 not 4150 The Receipt I looked at is 10yrs. old and then my R hand doesn't type very well either so I may have hit the wrong number. Sorry about that!
But here is the lock side and you can see I have mine turned so that at the lower side goes all the way down. I can loosen it and put it back on track but then I have at least 1/2" if not more before stopping it at the lowest possible. The Wire is just preventing it from unscrewing and loosing the knob. Again! I had a problem when I first bought the Ym2000 and ordered then correct setup. Been fine every since. When you have the handle as far as it will go down then go set the 3 point control valve. The adjustment on the side of the Control Valve with the set pin Adj. pointing straight up to start, Neutral. Mine stays in that Pos. now and no problems....

That's not my experience at all. FEL buckets may drift, but 3point hydraulics do have to stay where you put them for hours or longer. And it is good that most do, because otherwise none of us could pull a mower or a implement without constantly having to fiddle with the position of the lift. Imagine trying to plow a field with a plow that kept diving. Ugly.....

The feedback lever that senses the position of the 3-point arm, is linked to provide more hydraulic pressure as the implement falls. I think this automatic sensing and feedback is what maintains a plow etc at constant level.

I'll be messing with it today to see if I can make some adjustments on the 3 point. I brought it in the shop yesterday and noticed hydraulic oil dripping from one of the 3 point lift arms. Look like it will need some attention.
This is a rescue tractor that I paid $500.00 for so I don't mind the repairs. I replaced the front tires and rear wheels and tires.
It came with the loader but no bucket. I found a destroyed Kubota bucket for $60.00 and spent a weekend hammering and welding to make it work.
It needs new hydraulic lines for the loader which will be coming soon.
My goal is to make as reliable as possible.

Thanks for all the input.

When the tractor is on and the position lever is in place they all will stay put. I'm talking when the tractor is cut off. When running the feedback mechanism knows where it should be and keeps it there by adding fluid if it starts to let down a bit.

Get those o rings from Hoye. The Japanese spec and impossible to find local. But anyway pull the bolt off the arm slide the arm off the spkined shaft. Take the oring out that's behind it, new one in there and out it back togeather. It takes about 5 mins per side and the o rings are like $2 each. Mine leaked when tractor was hot, now it hasn't leaked a drop since I out new o rings in .

So I went to remove the right lift arm and the bolt was loose. There was side to side slop in the arms. I pulled off the arm and inspected the o-ring. it looked good so I put it back together. I'll keep an eye on it but it looks to be good.

I lifted the 3 point with the box blade then shut the tractor off. It took 10 minutes for it to drop to the ground. Pretty sure I can live with this.

As far as the loader creep I'm convinced it is an issue with the 3 point valve itself. I may have to live with this as well.
