3-Point Hitch BX23 3Pt hitch problem! Need help again!

[jgheck]

I was able to solve the problem with the sticking 3-point hitch lowering speed knob. I now have a bigger problem and need your help. I removed the backhoe and I can not keep the 3 point hitch to stay in any set position. It always falls down. It raises and lowers Ok, but will not stay in any set position. The FEL works fine and so did the backhoe. I do not have a repair manual on the BX23 at this time. I guess I need to get one. Is there a separate relief valve for the Three point system?
Any help on this would be appreciated. Thanks again. The help I got yesterday about the sticking lowering speed knob was very useful and I thank all that replied.

Hi Maybe you have the 3pt lower knob to wide open. Try closing and just crack little bit like 2-3 seconds for implement to lower. Just suggesting.

Thanks, but I have tried that and that does not help. No matter what position I have the control lever in the back blade just drops. The control lever does not move as it drops. I would guess it would be in the valve. Thanks for responding. Sure hope others may have some experience with this. I have been searching and haven't had much luck at this point.

You mention the lowering speed knob was frozen, and that you got it un stuck. What im thinking/worried about is there there was or now is internal damage to the valve allowing fluid to bypass something and the leakdown you experience. Your control lever would still function normally as stated.

How long does it take for the hitch to lower, and how much weight do you have on it? To determine whether the cylinder seals or the valve is leaking, raise the hitch and close off the speed control valve. If the hitch stays up, you have a bad control valve. If it still falls at the same rate, then the piston seals are leaking by. If it falls slower, piston seals and valve are both leaking by.

Good 2 know. Racking brain to help as no response. Maybe lack use (BH on years) has lead to dry seals? Power stearing seal fluid or just use much? don't flame

Thanx PR

Hi Ron,

Thanks for the reply. When I raise it up and close the lowering speed valve it still falls quickly. It doesn't make any difference if the speed control valve is closed or open it still false quickly. The control lever seems to be working fine. When I put it in the raise position it raises the three point hitch just fine and when it gets to the top of the lift the control handle will move to neutral. I was told this is suppose to happen. Even when it goes to neutral the hitch falls. It will go all the way down to the ground. It will not stop even if I close the speed control valve.
Arsenix thank you for your response as well. I think I am narrowing it down. Hopefully I will get a little more information before I start tearing into it.

Hi Stargazer, I agree that maybe the seals are dry. Don't know if in time they will work again or not. I don't understand this comment though "Power stearing seal fluid or just use much? don't flame" could you explain this. Thanks.

jgheck,

jgheck,

Hi JJ,

I sent you an email back. I was wondering if there is any Kubota repair manuals that can be downloaded? I do not have a BX23 repair manual, but will be getting one. I am in the process of taking the fenders, gas tank, rops, seat, etc... off to get to the hydraulic piston. I understand it is under the gas tank. I hope to have that off in the next hour. Does anyone have a picture from the manual of the piston for the 3pt hitch. I believe that is where the problem now exists. I am not sure either if there is a separate relief valve for the 3pt hitch as well. I understand that some tractors have a separate relief valve for the 3pt hitch. Any help is appreciated.

Thanks to all that have replied so far. I will post the solution to this problem when it is solved.

Jim

If the only hyd you have is the 3pt, and the pump, then there is a relief valve on the 3pt. The BH would have it's own relief valve.

I believe I would take a pressure reading on the 3pt valve before tearing into it. If you have a gage, install it just after the pump. Put a heavy load on the 3pt and raise it up until the relief goes, and read the pressure, and then move the lever to neutral and read the pressure again.

Things that can go wrong with the 3pt, are relief valve sticking, 3pt valve leaking, 3pt safety valve leaking, piston seals leaking.

The purpose of the descent knob is to let the fluid out of the 3pt cyl at a certain rate, or block all fluid flowing out of the 3pt.

Have a section under Kubota where you select the tractor components you are interested in and they email a schematic.

I don't know on the BX23 if there is only one relief valve or not. That is something that I called the dealer about and they were going to check with Kubota. The descent know is working ok I believe. I have taken everything off now and am able to see all the hydraulics. I need to get a manual though or have a picture to know what the various components are. I was hoping someone would have a picture of it. I will take some pictures and maybe someone could Identify the various parts. Thanks for your help.

Go here and download your parts manual. Also get the loader and backhoe at the same time because if you go back to load the loader you have to reask for the BX.

jgheck probably someone already mentioned this but disconnect and reconnect all the hoses, also go threw a full range of motion with you FEL. As you do the hose dance visibly inspect the end of each fitting.

Hi What i meant is the power steering leal sealer in bottle from car store. other was just use up/down to see if fluid would loosen. no comment if sealer is approved

Stargazer thanks for the information.

I actually did use the tractor and FEL with the back blade, even though the blade would not stay up. I thought that maybe using it would help since it hadn't been used for a long time. No such luck. The lowering speed adjustment seems to be working. It must be in the piston I am thinking.
