BX Quick disconnect problem on snowblower

[yooper jim]

Help Do I try a new QD????

Thought I'd try the new snowblower with hydro chute before the snow flies. Has red and blue hoses and are the center two QD's on the FEL connections (left and right chute). The chute motor rotates in one direction and locks up in the other direction. (pulled the gear off the motor to see if chute is jammed and it is not.)...... With gear off will rotate in one dirction only.

So..... I figure QD problem Try 50 times to connect and reconnect. Same thing. Put red and blue on white and yellow QD's and I works fine (obviously) the joy stick is the wrong direction. What is the deal? BTW Hydro dozer blade works fine as does FEL.

Thanks Jim

Which BX do you have? I had a similar problem the first time I hooked up my 4 way front snow blade. The angle cylinder would extend but not retract. Turned out I had the hoses cross connected - one on one circuit, the other on the other circuit. I do recall that on the 60 series BXs, the outer two male QCs are one circuit and the inner two are the other circuit. I think the outer two are FEL up/down, but don't quote me on it. I used colored tape to mark which hose goes where, but it's all disconnected now and in storage.

It's a BX2660. You are right the outer two QD (Y&W) are up and down FEL. So up and down circuit for quick hitch. I would think that center two QD's (R&B) is the other circuit and if switched, should only make the left and right on the joy stick backwards. I'll try switching R&B in the morning, but I'm sure I tried that.

Assuming you have the right valve, just push the lever to the right past the detent.

It is not a "problem", but a "feature" called Regen or the Regenerative function of the valve. Some call it "fast dump" also.

Here is a thread that explains it very well: 3 position valve-vs-4 position valve - TractorByNet.com

But in a nutshell, you need to follow Kevin's advice:

just push the lever to the right past the detent.

An additional note-the chute will rotate very fast once you move the lever past the detent.

There is no detent on the left and right movement of the joy stick. It just springs back. This was all bought as a package from the kubota dealer, so the valve and all should be correct. I just don't understand why it works on the one circuit and not the other. If I hook a double action cyl to this, it work just fine.

It (the detent) should be there if you have a 4-way valve-and all the newer machine com with them. It is not a detent like the float, the stick will still come back to neutral after you let it go.

If you do not push the lever far enough, then both hoses are pressurized, that is why the motor is "locking up" Your bucket works because of the wieght of it pulling it down.


Read the first post of the thread I linked carefully. Also do a search of the term "regen" for LOTS of post's just like this:thumbsup:

Just a thought here,the detent in the loader valve maybe a little difficult to overcome,like pushing the loader valve into float position.You may have to push harder to get past the detent-it can feel quite abrupt.Good Luck!

Maybe I'm wrong, but when the blue line is pressurized (move stick right) the red line acts as a return line. Move stick left and red is pressurized. Blue becomes return line. That should reverse direction of hyd motor. It works a DA cyl on blade correctly (left - right angle). I read the post on regen etc. 3 - 4 way makes sense.

You are not wrong, but when the regen is active (in the first portion of the joystick throw on Kubota's) both lines are pressurized.

Pushing to the right, Far to the right will solve your problem. I know I ran into it last winter when I installed my blower with the hydro rotation. push the stick right and it stops but it can go more. There is a detent there to overcome. Mine was very hard the first time but now its fine.

See post 4......the lever will go right twice as far as left IF you have the right valve.

I'm not following the need to go past the detent to the right on the joy stick. I know it's there on mine, but I don't need to go past the detent to make my hydraulic blade swing right. Unless this is something unique to hydraulic shoot rotators, I don't see why the OP would need to push past the detent. I thought that only effects the speed or force applied in that circuit.

He did say his DA cylinder for blade angle works right, so I'm thinking he may have a bad QC on one of the rotator hoses. Hard to tell from here :laughing:

The problem is that both lines have pressure in them while the joystick is in the regen position.

The chute has a MOTOR not a cylinder. You MUST go past the detent to operate it. If he does not have the detent then the control is wrong.

To the right is regen first, then normal hydraulic.

 

[CHDinCT]

OK, just reviewed the the thread on regen and I see it now. With a cylinder in the circuit, the cylinder side has more volume than the rod side resulting in more force being applied to that side, so while both sides of the cylinder are pressurized, the cylinder will extend albeit more slowly than without regen. Since the rotator is a motor and not a cylinder, the same principles don't apply and the OP would need to push past the the detent to NOT be in regen mode. This would explain why I don't have the same issues with hydraulically angling my front blade.

Yooper Jim, if you have a BX2660, you have a detent all the way right - just push hard and your joystick will click past it.

Didn't have time to play today. Will be at it Saturday. Thanks to all and will let you know.

 

[yooper jim]

What a dumb *****! All the way right on the stick. I had no idea that was even there. Thanks to all. It works and I feel stupid. You guys are great.

Thanks again
Jim

Cool! That's why we all hang out here,eh?
