BX25 Remote Valve Project

[CORamos]

When the back hoe is off, the power beyond return hose is plugged into the power beyond port on the joystick.When the back hoe is on this hose plugs into the power beyond of the backhoe, the pressure in hose from the back hoe is plugged into the power beyond port on the joystick and the tank return line from the back hoe goes into a quick disconnect T'ed into the Joystick tank line. When I use the back hoe my 3PH arms and hydraulic top link are removed so there is no real need for the joy stick but the option remains if needed. I did have to make sure all the hoses were long enough to facilitate taking off and putting on the back hoe. I'll post some pics later if you like.

I'd be interested in those pics. I still haven't worked out how I will connect my grapple, so I'm looking for ideas.

Hmm, not a bad idea. Not sure why I didn't think about running it in series, but I'll give that some thought. That set up would leave both circuits open with the backhoe hooked up, though I can't see when I'd need both. How do you hook yours up when the BH is off - did you leave enough hose length to plug in to the tractor side BH connections?

A couple more pic's. I have since added nylon hose protection. Ordered 20' of 1.75" ID nylon hose protection from McMaster Carr. Plenty left over for my eventual grapple lines.

Chris,

How are you planning on routing the line to the front for the grapple?

Well since I don't have the grapple yet, don't really know, but I'm hoping to run lines under the tractor if I can find locations with suitable protection. That is until the hoses get to the FEL stanchion where they'll follow the existing curl cylinder lines presumably. I have had the thought of using quick connects at the back end so that the main run of hoses stay on the tractor, then use short pieces for the final connections to the auxiliary valve at the back. Just some thinking at this point.

Chris in case of an accident, perhaps roll to the right,
is the posistioning of the valve and bracket going to hurt you?

Have you considered re-routing the hoses albeit making them longer,
to move them out from underfoot on the BH? Getting on and off the
hoe is a safety issue w/ me. It is tight and you MUST be sure the
RPM's are at idle or OFF and dipper is on ground for it is so easy to
tag a valve handle w/ your butt or T shirt and make it move getting
on and off. I wish there was a simple lockout for egress and degress.
So I guess my thoughts are do the hoses present a trip hazard?

Thanx for the detailed presentation, I know, it takes a LOT of work.
Thank You.

Artisan, I'm only planning on rolling if I do, to the left :laughing: But seriously, if I'm belted in, it shouldn't be a problem, I think. The valve is actually a little behind me though I suppose it's possible I could hit it with something in a roll. Any roll should be slow, unlike a, say, a car at 50 mph, so bodily damage should be minimal if at all.

As far as the hoses getting in the way, it really isn't a problem. I will take some pic's when I can from the backhoe seat so folks can see what it looks like from the operator's perspective. Again, I did add hose protection and used velcro straps to cinch the lines up to the ROPS, etc.

To the left huh? Must be a NASCAR fan...

I use some nice Cable Ties in a puke orange flavor that
are removable that you might like;

Artisan ,

Dealing with pressure in the return line.

It is possible to generate some pressure in the return lines using extra fittings like tee's. You don't want back pressure on any valve, so it would be a good idea to make the line from the tee a larger size going to the tank.

Someone mentioned about not having good hyd function when using detent. You should have normal function with detent installed, including feather and full cyl action up to the detent position, and in detent, will allow fluid to flow continuously.

Detent options on some spools.

If you really don't need/want to run hoses to the front for grapple, and have some extra money, then I would suggest either a third function valve to operate the grapple connected to the PB OUT of the FEL.

You could also do the diverter thing using the curl circuit and a thumb switch to operate a grapple.

Thank you J_J

I don't think I ever circled back on this to show the finished hydraulic top link installation. Got that all set up now and really enjoying the ability to tilt my rear implements at will. Just had to extend and re-rout the tank return line a little to avoid interference with the top link.

Used my box blade and rake a few weeks ago and it made things much easier. Also came in handy when I hooked up my carry all to move some firewood (hat tip to Wrooster and CTF for the carryall idea). Anyway, here's a few pic's of the top link fully extended and retracted. Plans are still to add the grapple thumb to the FEL next Spring.

CHDinCT you are to be complimented for starting this excellent thread. My compliments also extend to other members for their valuable inputs.

I would like to install a remote valve on my BX25; however, I am having difficulty figuring out how those hydraulic lines attached to the backhoe actually work. Might some members be able to shed a bit of light on a few questions please? For example:

1) Is there a diagram available that illustrates how the oil flows through the three hydraulic lines between the BX25 and the BT601?
2) Might there be a diagram that shows to which ports on the remote valve the above hydraulic lines should be connected to?
3) Finally, is there a diagram showing which ports on the remote valve would be connected to two hydraulic cylinders on a new attachment (other than the BT601)?
