FINALLY!! New B2650 but is this abnormal?

[Mike.O]

Finally!! After weeks of waiting my new B2650 showed up yesterday with BH and FEL. I jumped right on it and put 4 low rmp hours on it. What an amazingly powerful little machine. HIGHLY RECOMMEND!!

So my question.......After digging some rocks with the backhoe, I cleaned her off and put her in her new home in the garage. I walk into the garage today and I see the left BH stabilizer arm has dropped, from fully up down to the garage floor. Only the left side, the right is still upright, and has maybe 1/2" of sag, which I would assume is normal. Now if I pick up on the sagging stabilizer (with the machine off), I can physically lift the stabilizer about half way back up. This strikes me as rather unusual. I'm not all that familiar on these machines as this is my first one.

Any ideas / input if this is normal/abnormal?

something that new.....I think you need to talk to the dealer.
My BX25D - 3 years old, 200 hours or so, will droop the arms all the way down.....over two weeks of me not using it! If I use it once or twice a week it does not fall at all. IF I curl the BH bucket, it will uncurl after a week or so too.

YOURS being brand new, seems a seal is quitting too soon!

If you can physically pick up on the out rigger, it sure sounds to me its air bound. If it were me, id put the out riggers down just so they touch the ground and crack the hydraulic fitting to see if any air spits out.

groomerbuck. any specific fitting to attempt to bleed. I would assume to go for the top one when the out rigger is down. Aren't these systems supposed to be self bleeding? Is it still possible to air lock?

 

[groomerbuck]

I would just crack the fitting on the out rigger cylinder. Just make sure the out riggers are on the ground to eliminate the possibility of them crashing down.
Im not a hydraulic expert, but in my experience air can mess with any system.

I would call your dealer first. Brand new machine, they should deal with fixing it. Remember, high pressure hydraulic fluid can do serious injury to a person if you are not careful.

I guess this is the draw back of living in Connecticut and buying a tractor from Kentucky LOL.

I will call them tomorrow or Monday to see how they typically handle things like this.

I reset the out riggers into the fully upward position and took a time stamped photo tonight. I will check in the morning and see if it has dropped again and take a time stamped photo to show how much drop is happening in a relatively short time period. I plan on running it for a few hours tomorrow, so if it is air or something like that, maybe it will bleed itself.

Did the stabilizer lift the tractor/work ok? If so, I doubt that it has air. If it is functioning normally but settling overnight, it sounds like a seal not holding in the hydraulic valve.
If you call the dealer, they will need to know specifics- does it function properly or not, and the fact that one is holding and the other is not.

Could you just cycle the outriggers up and down 10 times or so ? that might work out any air in them. Maybe even crack the hydro fill plug so the air can get out....

Yes it is. Sometimes cheaper isn't always better when something goes wrong.

Sounds like the cylinder is bad, oil seeping past the seal. I parked my 1953 backhoe in the fall with the stabilizers up, and they're exactly where I left them 7 months ago. There's no excuse for that. Hopefully they make good on it.

Thanks for the replies!

All works perfectly fine when in operation and lifts the tractor as it should. I plan on going out and moving a few rocks around today, so I will cycle everything and use it to see if any potential air can be worked out. Not looking good tho.

See attached pictures with corresponding times on them showing the amount of sag in less that 24 hours. Seems unacceptable.

if both sides are doing it ....then , maybe everything is "ok" - ONLY one side?? That says a seal is bad to me ! Dealer should be called.

Is there any chance you are moving the controls after you shut the engine down? Or that the stabilizer control is not exactly centered when the machine is shut down?

I ask because on my U35-4 in the manual it states that you leave the key in run position after turning the engine off and move the controls to relieve hydraulic pressure. I would guess that would make your stabilizers sag.

 

[fatjay]

Especially if it's only one side, the cylinder is probably bad. Did you try putting yourself in the air, then leaving it for a few hours to see if it drifts down?

 

[Mike.O]

Fatjay, I just saw your response, I will try that tomorrow.

As for an update, Barlows is sending me a new stabilizer cylinder and I'm going to put it on. Not convinced that this is the cause, but we'll see after I put it on.

After a few hours digging a stump today, it looks like the stabilizer is getting much worse and is drifting at a much faster rate.

I have an older b21 tlb and none of my hydraulic cylinders leak down or sag ever. All hydraulic systems should self bleed. Also check and see if you have a pin used to hold stabilizer controls in place for transporting put pin overnight and recheck.
