Rear Remotes on a BX

[jpr62902]

Mr. Mad,

I'm running the risk of sounding like a total idiot here, since I know less about hydraulics, than say, my wife's moods, but the BX22 already has "to" and "from" connections for the hydraulics to connect to the backhoe (the BX BH is not powered by a pto pump, but by the tractor's hydraulics). That said, I think Junkman's problem is between the already existing hose and port at the back of the tractor and the ports on his valve, so I don't think its necessary to "T" into the FEL connections. Did I explain that okay?

(EDIT) Okay, I just reread this thread and I think I sounded like a total idiot there -- Isn't it possible to hook up the valve to the QD's a the back of the BX22?

The whole idea of the rear remotes is to be able to use them while the 3pt is in use with implements. Since the backhoe has only 2 hoses it must not have PB capability and must be last in line. Although I am not familiar with the BX hydraulic setup, I am with others of like design where the 3pt is disabled when the backhoe is connected. I'll bet that when the backhoe is not connected there is a jumper hose between the QD's where the backhoe connects.

That being said, the valve provided by Kubota for the rear remote does have power beyond and must be connected as such with the third connection being for the low pressure return back to tank.

I believe the parts for the rear remotes from Kubota, at least the valves and hose kits, are for all B and BX series tractors. Each of these has different connection issues. It looks like some engineer forgot about the BX23 that comes with a backhoe as standard equipment.

If I get some time tomorrow I will go to a local dealer and take a look for myself.

I think I'm beginning to understand. Its not like electricity, where you only need a "to" and a "from." You need a 3rd line (would that act like a bypass?) as a return to the reservoir, if you need to run other things "down the line." That said, If the BH is connected on the BX22, you can still raise the MMM, which is linked to the 3pt. Now I'm really confused. Thanks for trying to educate me, though.

Hey Junkman, now this is funny, my wife comes in the room while I am looking at a picture of your tractor and new valve. She keeps looking at the picture then finally says "hey look honey that guy went and put a jet engine of some kind on his tractor to make it go faster" /forums/images/graemlins/shocked.gif /forums/images/graemlins/shocked.gif.... I laughed so hard I nearly fell out of my chair......she was serious she really thought you had mounted an jet engine on the back of your tractor....

I have thought about the rear remotes on my BX23. MAD, can you tell me why it would not work to hook into the BH lines. My thought is this, when the backhoe is off, I have to plug the BH hyd. lines back into each other to complete the loop. Why not plug these into the remote valve? Then I can use the tractor hyd. for a rear remote.

I will try to explain that to all, and I am just picking MadReferee's post as the one that is handy.

The rear remote has 3 hoses in the kit and a male and female disconnect. Also contained in the kit is a small adapter that goes on the transmission after you remove a plug. This is the return from the valve to the sump. The instruction say to run the two long hoses to the front of the tractor and </font><font color="blue" class="small">(

8) Disconnect the loaders power beyond hose (1 & 2). Connect the remote valve pump hose (A) with male quick coupler to the power beyond hose (1) off the loader valve. Connect the remote valve power beyond hose (B) with female quick coupler to the power beyond hose (2) off the tractor. See the photo to the right. )</font>

This is where the problem lies... the quick disconnects that they supply are different than the quick disconnects that are in the kit. (See Photo). The supplied quick disconnects are on the left and the type that are on the tractor are on the right. My question to Kubota was... do you remove the factory installed quick disconnects and use the quick disconnects that are supplied in the kit to make the connections? If this is the case, then they would need to supply 2 complete sets (1 male, 1 female = 1 set) of quick disconnects to complete the installation. I have a feeling that they want you to have different type of quick disconnects, so if the loader and valve is removed, that the rear remote isn't disturbed. I know that I can make it work with the spare quick disconnects that I have, but I want to know what Kubota intended before I do this.
This is being installed on a BX22, which I believe has a different plumbing set up from the rest of the BX series. If anyone wants to know the lengths of the hoses and types of ends, I will post them later on. After seeing this set up, I realize that I could have done it less expensively by not going with the Kubota kit. I chose to do it this way, because I didn't want to jeopardize my warranty if something went wrong later on. I know now that I could have had this set up made up locally for less. This is an advantage that others will have from information that I will post at a later date. I just want to get this set up correctly the "Kubota way".
I got a call back today from technical services in CA and they informed me that the engineer that designed the system was out until Monday and that I should just wait.

The coupler supplied appears to be a SafeWay series 70 coupler but I could be wrong on that. If so, they are noted for being able to connect and disconnect under full pressure. I can see no other reason for having this type of coupler. It almost appears that the engineer just mis-spec'd the couplers.

All I can add is the connectors on the left are the same as the ones on my BX1500.

 

[Junkman]

Ken...... thanks for that information.... the quick disconnects on the BX22 are the type on the right. You may have answered the question for me..... the kit is different for the BX1500 than the kit for the BX22?????... Now the next question to be answered is.... does Kubota know that they are using two different disconnects on the BX series? I am also wondering if there might be a change of connectors based on the year of manufacture along with the model of the tractor? What month/year did you purchase your BX1500 tractor????? Does anyone else have the connector on their BX that is like the one pictured on the left side? We might be able to figure this out before the engineer gets back on Monday from Boston!! /forums/images/graemlins/grin.gif

My BX22 has the connector type on the left, but the hydraulic lines used for my front blade mount are of the type on the right. (As you know, on the 22 the valve stays with the loader; therefore I had to plumb in QD's of similar type to the blade mount lines in order to remove the loader but keep the valve with the tractor.) Attached is a photo showing both types.
I suspect that somewhere along the line Kubota changed types - or they just use whatever type they can buy cheaper, and therefore sometimes you get the type on the left and sometimes the other.
