Bx25 backhoe sags when parked

[bx25jim]

pump running or not it will do that... once you position a cyl, then get off the spool valve, it is just the spool seal and the cyl seals to hold it...

the circuit is not being fed constant pressure from the pump.

3pt systems can use unloading and circuit regeneration to keep a sagging 3pt load lifted to near the same point, usually in a hunting or bobbing motion depending on the leak. circuit leaks, linkage signals repres of the system, then when in the correct position, circuit unloads.

that's differend from back hoe hyds and a multi circuit spool valve.

I understand what you are saying, but my point was, I could run the tractor for a few hours and not have it creep down. But let it set the same amount of time with out it running, and it would start to settle/creep. :thumbsup:

I also use the pins that are used to store the boom and keep it from swinging left to right when moving around. But the bucket itself does not have one. Thats the only one that will settle. I do however let all the pressure of my lines by moving all the levers as the book recommends. I dont have a problem with it doing what it does though unless it starts to get excessive. A good friend has a larger Kubota with a backhoe that does the exact same thing when not being used for a period of time. So no problems.....Jim

um.. the rate of creep setting should be less setting static than moving, assuming both circuits not powered. i'd think the moving running machine, due to vibration, might actually make creep worse.

now if you are using and constantly regenerating a circuit, then you are not compairing time to time.

if you take 2 identical machine that have the dipper circuit 'creep' at the same rate when off, and you raise both, then turn one machine off and leave the other running, but don't regen the dipper circuit.. they should hit the ground ABOUT the same time..

There again, all I can offer is my own observation as to what mine does. I admit, I know nothing of hydraulics except for knowing how to fix a leak if need be. Just letting the OP know that he is not the only one with a system that creeps when not used for a while. Thanks Jim....

I used to have this problem, then I replaced the hydro oil with straight water, which is much thicker than oil, and I do not have the hydro leak down anymore. Plus, replacing the fluid in the trans, etc is now free! I just pull up the garden hose and fill er up! I am a genius.

In freezing weather the leak down must be really slow!

What weight water did you use? Was this the hard water or soft water? And just one more.....was it filtered or unfiltered before the install? We really dont have hard freezes here in the south, and may just have to try it....We have well water and it filtered.....No chlorine... Will that suffice.....

BX25D owner here. My stabilizers will slowly leak down over time and the bucket will uncurl when it sets. No big deal.

Next time I take the BH off i'll do the strap thing. Last fall I ended up with some small hydro oil puddles on the floor from the stabilizers leaking down. I knew I should have put them down but I didn't want any more floor space taken.

Yep on all points. 'Forget about it'.

Yep normal. What frustrating to me is during the storage of my BH off the tractor and on a dolly, the stabilizer feet slowly deploy making the BH bigger and harder to maneuver around. Have to connect up to the tractor to raise them up. Careful that you don't park the dolly such that it gets trapped because the legs sagged. I am now using some long cabinet making clamps to keep them upright. Tried some cheap zip ties and they stretched and broke.

Good point. I tie them together with nylon rope.

Thanks guys, I feel better now.
