Rear remote on a BX22.....

[Junkman]

I had previously posted about this and here is a link to the thread. if you would like to know what originally transpired.
Today, I finally got around to installing the Kubota rear remotes. To say the least, the instructions were poor. Mounting the valve was the easy part. Once I got the right hand tire off, it was easy to get to the oil return port. Loaded tires are not something you want to handle a lot. Getting it back on is also a pain. Getting back to the rear remote. I put the 3 hoses into a nylon protective sleeve and hooked up the return line at the valve and the JIC fitting. For those that might want to add rear remotes, the fitting is a 9/18-18 JIC adapter and the hose is approximately 38" long.

This next picture is where the JIC fitting goes....

This is what it looks like with the hoses going to the return and forward to the front connections.. As you can see, it is a very tight fit. I used the same nylon protective cover on the two hoses that went to the front. This turns out to be a big problem, because the only way to the front is by going on the inside of the frame. After struggling for more than an hour, I was finally able to get the hoses routed so they were snug against the frame. When I finally had everything hooked up and secure, I started the engine to try the remote valve and check for leaks. Great, no leaks and everything worked the way it was supposed to. Gave the throttle a little kick and suddenly, it sounded like the drive-line was going to fall out the bottom. Shut down the engine and crawled under to see what had happened. Apparently when I put pressure to the valve, the lines moved and the nylon covering was shredded by the plastic fan. The good news was that both the fan and the hoses themselves were not damaged. Spent about 30 minutes looking under there to see if there was a place that it could be secured to, but there isn't. I have come to the conclusion that I will have to drill two 1/4" holes in the floor pan and use a wire tie to secure it to the pan so the cooling fan doesn't take a second bite. I also realize that it might take a second set of holes to secure the top section of the hoses to the floor pan if there is any movement that I haven't accounted for as yet.

Junkman, you sure have some nice looking carpet in your garage. How do you keep it so clean?????????????????

Ok, seriously, did you buy a Kubota kit or DIY parts?

Someday, I hope to mount one on my 2200. Someone posted very detailed info on that and I printed it off to assist me......

Best wishes,
Ron

The one problem that I see for everyone that uses the Kubota supplied kit or makes up their own kit, is this clearance. I also realize now that there is an easier way to do this on the BX22. All I would have had to do was to use shorter hoses and run them to the backhoe connection. This would have accomplished the same thing. I am now torn between removing the hoses that I have just installed and having new ones made or drilling the floor pan and gambling that the fan never goes after the nylon covering again. If I had used a smaller nylon covering, it would have worked out better, but that is what I had, so I went with it.
Here is a picture of the valve installed and plumbed. Unfortunately, I had to lower the valve because the 38" return line wasn't long enough when the valve is positioned as in this picture. The valve is now located on the "S" curve section of the ROPS, not where I had wanted it. I am not sure that it isn't going to be too close to my leg when using the backhoe.

I keep the carpet clean by only using it for pictures. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

I purchased the Kubota Kits. One kit is the valve and the other kit is the hoses and JIC adapter. If I had it to do all over again, I believe that I could do it less expensively by ordering non Kubota parts. I might still remove the long hoses and order new hoses to hook up to the hoe hydraulics. I really don't like drilling holes if there is a better way.

I hate to ask, but what are "rear remotes" for?

 

[Junkman]

I intend to use the rear remote for the adjustable 3 point hitch top link. When I have time, I am also going to add a hydraulic cylinder to my landscape rake so I don't have to get off the tractor to turn it. The second cylinder will require a second valve to be added to the existing one. This translates into more $$$...... Some people see this as a lazy mans toy, but at my age, the less that I have to climb on and off the tractor, the better it is and the more that I can get done.

Can't sleep... my mind is still thinking about these hoses. Question.... since there are only two lines to the backhoe and when you remove the backhoe, you join these two lines together, can these two lines be used to power the rear remote? The reason that I ask this question is the rear remote has a return line back to the reservoir. The backhoe doesn't. If I were to connect into the backhoe lines, would the return line in the valve "steal" the pressure that the backhoe needs to operate? I have learned that the Kubota valve is a "open center" and that the hydraulic oil is flowing through the valve at all times, or at least I believe that is the function of an open center valve. What do you hydraulic guru's say??? Will my idea to hook into the backhoe lines work without disrupting the backhoe? Thanks for your input...

Just went back to the original thread that I had started a few months ago. After reading MadReferee's post, I believe that this won't work. Guess that I will just take a Valium /forums/images/graemlins/crazy.gif and forget about this till I get the answer from someone that understands all this plumbing. /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif Going to sleep now, and I hope that sometime tomorrow someone will have solved this problem for me.... I feel like Henro... not knowing if I should drill holes or not.....

The last valve in the series doen't have to have power beyond, but all the rest does. That is the reason the backhoe has only two lines.

 

[Junkman]

Jerry... what happens if you tap into these two lines and add a return line through the rear remote valve? Will the backhoe still work or will I have "stolen" all the fluid and put it back into the reservoir???? /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

 

[MadReferee]

Most backhoe setups must be the last valve in line since they have no power beyond. Also, most backhoe setups are plumbed so that the 3pt and any valve after the loader is disabled (or must be disabled manually) thus effectively making the backhoe the last valve in the circuit.

I have seen the plumbing for backhoes done many different ways, some right, some wrong. One thing that you do not want to do is have the return to tank line dumping into the high pressure power beyond line when there are working valves down stream. The most common way to plumb that I have seen on Kubotas (and it's not correct by the way) is to take the loader's PB line and run it to the rear for the backhoe and the other backhoe line goes to the loader hydraulic block to continue the circuit. This plumbing method requires that the 3pt be disabled manually which means the rest of the circuit is then really the return to tank circuit.

Now I have seen a remote valve connected to the backhoe QD plumbing as above (and adding a seperate return to tank line) and then running the backhoe from the valve's work ports by keeping the lever in an open position. It generates some heat in the remote valve but it does work.

I have not looked at the BX plumbing so I cannot give you a definitive answer. However, if you tell me where the 2 lines that connect to the backhoe eventually terminate I could give you a good answer.

I will try to post a schematic of what you need to do this evening. I think I have one with a loader valve, two different control valves and a two line backhoe all in series.

 

[Junkman]

I will have to try to trace them to see where they come from and where they go. It is so tight in there, that it might not be possible to figure out there origins. I looked last night, but it wasn't evident and I figured that I would explore more in daylight. Thanks.. Junk...

 

[Junkman]

One of the backhoe lines is a Siamese with the line that runs up front, so I assume that it the pressure feed line. The other line goes back into the transmission, so I assume that is a return line. These are usually hooked up to the backhoe valve and when the backhoe is removed, you couple them together.... thanks....

Junkman,

Just for the sake of accuracy...should that be 9/16-18? I think so but am not absolutely sure... /forums/images/graemlins/confused.gif

 

[Junkman]

You are correct..... poor eyesight proof reading when I am tires.... ah.... tired..... Junk.... /forums/images/graemlins/grin.gif

 

[Junkman]

The question is now officially resolved. Tonight I decided that I didn't want to drill holes in my floor pan to secure the hoses if it wasn't absolutely necessary, so I pulled the hoses out from under the tractor. I then rerouted them to the back of the tractor temporally and hooked them to the backhoe line. I tried the backhoe outriggers and they lifted the rear of the tractor as usual. I have to assume now that this will work. On Tuesday, I am off to the local hydraulic supplier to purchase two new hoses of the proper length for this "modification" to the BX kit that I purchased. If you have anything other than the BX22/23 tractor, you will still need to run the hoses to the front of the tractor if you want rear remotes. I will post pictures when this is complete..... Junk..

Junkman,
Here is the picture that I told you, I would post.
