BX22 BH question

RebelYell · Dec 20, 2003

My BH drops slowly even when the engine is running almost full throttle. The BH has a great deal of power and I use it alot. The BH has done this from the first time I used it. I would estimate it drops an inch every 10 minutes or so, with the engine running. I would like to know if this occurs to other BX22's or if I have a problem. If this is not normal what should I check or should I take it straight to the dealer.

Hmmmm... Could you provide a bit more information? I assume that you mean that the bucket drifts downward from its "stowed" position when you're not using the BH, but I'm not sure. I'm pretty sure you don't mean that it moves only an inch per ten minutes when you are telling it to move via the control stick.

Anyway, for reference, my BX-23's BH bucket only moves an inch or two over a several day period when parked with the engine off. The stabilizers drift down maybe a quarter inch.

everything on my BX22 is rock solid with no movement for days... Just checked tonight and everything is where it was when I parked it 10 days ago.... I think that every machine is differant...

My 'hoe will drop an inch or two...but it takes over a week to do so! I am thinking you have a connector somewhere that has a slight leak...not enough to spoil performance when you are using it, but enough to release pressure just the same. Check the connections at the particular cylinder that is slipping, too.

I'd be contacting your dealer.

I meant while the bucket is in use not in the stowed position. The hoe works great and I have done a great deal of work with it. I am posting several of my projects in the projects forum tionight. Honestly, if it moved in the stowed position then I would be bending or breaking the pins; however, when I want to pull the bottom pin out I always have to move the BH up to take the pressure off the pin. This is why, I would guess, the pins are utilized. When I am using the hoe and I stop to take a break and/or evaluate the work I am doing; I can watch the hoe drop ever so slowly with the engine running. If I turn the engine off I can watch it drop faster. With the engine running almost full throttle and with everything hooked up correctly I would think the hoe should not drop. I have looked for leaks and even scratches on the pistons. I have been told the small hyd. pump may not be enough to hold the hoe in place. I may have a stuck valve for the top piston. I will get with the dealer. I was just hopin' for a bit of help here before I call them. It is nice to go through a few simple checks before calling the dealer.

It sounds like you have a bad spool in the hyd. valve that controls that part of the hoe or it may be that that joy stick is not adjusted properly. some how oil it getting out of that hyd cyl. either thu a bad valve or a bad connection. the hoe settling down after days of non use is normal.

On my BX22 I had one stablizer go. I had the tractor up on the stabilzers to check and after 5 minutes one side was back down. They needed to install one new stabilzer. After that I was good to go. Oh, before that they tried the new seals and that would not work.

Lastly, I used store my Backhoe on my dolly when not in use and reliave all pressre in lines (also on tractor too). I also use the backhoe pins when using the tractor but not using the backhoe. This helps prevent more pressure on system.

I would have the dealer check it out. Sounds like a backhoe piston is shot / internal leaking.
