back hoe joy stick

[f3504x4]

hi all, well i finally did it. bought a ck20hst. so far i'm really inpressed with the power this little beast has. after 4 hours of loader work i tried the backhoe. there was a leak at the front hdro fittings and the rear fittings so i brought it back to the dealer and it looks like he fixed it. no leaks yet. the question i have is i tried the hoe again today and now the left joy stick does not find center to well so the arm keeps moving very slow downward until i put it in the middle. is there an adjustment to make or should i bring it back? the only reason i don't want to bring it back is the dealer is about 45 min. away and i would have to leave it for a day or two. this will also give me some knowledge as i want to learn about the operations and repairs. if anyone could help i sure would appreciate it. thanks and have a great day, chris

It should go to a neutral detent position and all flow is stopped. I ordered service manuals for mine but don't have them yet. As soon as they arrive, dealer said another week, I go through it and see what it says. My dealer is more than happy to explain how to adjust or correct a problem without having to bring the machine in. It saves him time. Try calling him and maybe he can explain an easy fix. I have a CK30 with a joystick for the FEL. I imagine your BH has the same control.

victor, thanks for responding. i was wondwring if maybe air got in the line when they fixed the leak problem? it worked fine prior to the leak repair. i feel like my dealer is to busy for me now that the sale is over. he was great before the purchase and now he makes me feel like i'm bothering him. i know it is under warranty but i'm beginning to think that is only good for something major. i am mechanical and i want to learn more so i can just fix it myself and know it was done right. also how much are manuals? thanks, chris

het kioti john if your out there maybe you might have some input on this. thanks chris

Without seeing what is happening I'll take a guess and say that joint where the joystick hinges above the valve maybe dry and sticking. If you pull the rubber up to expose the two joysticks you will see the leverage point and the ball that control the valves. Just lubricate them with something if they seem dry. My two cents worth if it might help.

steve, thanks. i'll try that tom. i hope its as simple as that. chris

I would think the air has purged itself by now if you have cycled fully all the cylinders several times. My new FEL took about five full cycles each for the lift and bucket cylinders. Otherwise, it would jerk when it moved but the stick always came back to center. I think Steve might have the answer. Fixing a leak shouldn't have affected the joystick. I hope a little lube is all it needs. Keep us posted. The manual for my CK30HST was quoted by the dealer as 75-80.

We have had them stick also. Just spray with some wd40 or pb blaster and you should be going again.

The first step I always go for is lubricatioin when something is sticking. Left the boot at the base of the joystick and spray those connections, moving the stick while you're spraying. Make sure the bucket is already on the ground for safety.
If that doesn't work, send me a private message, and I'll get back to you. John

o.k. this is what i have so far. removed the boot on left joy stick for the backhoe. there are 3 cylinders (valves). the pattern is 1 on the left, 1 on the right and 1 in the front or 12:00 oclock position. the one in the 12:00 oclock you would push the stick foward. when you let go it does not come back to the middle position all the way causing the arm to slowly drop. i noticed about a 1/4" of play with the cylinder under the lever which pushes down on it. there is no play in the other two. when i push the stick foward it takes a few seconds for the arm to start moving down and when it does it jerks as if it finally engages. i don't know if there is a spring in there or if there is an adjustment. as i stated before it worked fine until i brought it back for the dealer to fix the leaks on the back hoe on the front and rear conections. he said it was orings and that seemed to stop the leaks. still need to keep an eye on it to make sure. i hope i explained this o.k. and would appreciate any feed back. thanks, chris

when you push the joystick to the 12 ptn, that's float. It's not supposed to come back to center, it's a non pressure drop that is often used when you're backdragging and want the bucket to follow the contours of the ground. If you only push it part way, you can power the bucket down instead of having it float down. With higher RPMs, that will happen faster.
Don't push it into float from high up, just power it down, and when you want to float, push it into that locked position.
You may just be getting air from somewhere, and it may be caused by floating that bucket if a seal is allowing any air in.
Pick up the loader, operate the functions a few times, power the bucket down and let it sit for 30 seconds. See if that makes it any better. John

john, the stick i'm talking about is for the backhoe. it is the left stick in the foward or 12 oclock pos. the little cylinder under the pivot point has about a 1/4" of play in it and wont come back to center. chris

That is a float position as well, and you have to bring it back to center yourself just as on the loader when in float. John

I didn't know that a BH had a float position. Maybe they just use the same joystick control. I've only used multiple lever controls before for a BH. One for each operation. If you go into float with the FEL joystick, you can definitely feel resistance then in locks forward. Does yours feel like that? I have to see my dealer on Monday. I ask him about your problem and see if he has an answer.

Yes, the boom stick has a float position (L control lever). This makes it much easier to scrape the bottom of a trench as you pull the dipper straight back, the boom will just follow the contour as you pull the bucket back toward you. John

hey guys', thanks for this info. i can't remember if it did this before i brought it back to the dealer. i thought both sticks felt the same. now i know on the fel the float is all the way foward and i can actually feel it go into float, but this is sloppy before i start to get any resistance pushing the stick foward and when i lifted the boot i could see about a 1/4" of play on the cylinder that pushes into the valve body. now the other controls dont do that and when it finally starts to push down on the cylinder it takes a couple of seconds before the boom actually engages and start to push into the dirt and when it does its quick and hard. i'v had it only 2 weeks and 1 of those weeks was wasted due to weather and dealer. already have 23 hours in just 3 actual work days. the way i'm going i will have to trade in every year for a new one. this tractor has more power than i thought it would. i was building a block retaining wall, blocks were 18" x 12" x 8" and was putting 7 at a time in the bucket and was in high gear with no problem with some of the small inclines. low was great. i'm learning very quickly about fel work and curling the bucket. can get a full bucket of clay and soil in every shot. i guess if i would want a change i would buy the cup holder kioti john wants so bad and may put a 25 hp motor in it just because. any more info on this joy stick would be appreciated. thanks, chris

the one time I ran a back hoe (JCB 224 or 244???) It had a detent on the left stick, but not if you moved it forward. The detent was on the left. You all probably think I'm crazy, but thats the way it was. You push it to full left, it'll stay there and the hoe will move to the left (slowly tho) with out you touching it. The only thing I could make of it was that somebody screwed up, and what should have floated the boom up/down, ended up being on the left side. Any thoughts?

Someone screwed up. There would be no real use for having this set up on the swing and not on the boom. They must have mixed the connetors wrong. John

I have to go out of town for a few days, but when I get back, I'll check into this in more detail and get back to you.
I believe this can be adjusted out, but I'll have to look at it.
