EDIT: FYI in case anyone stumbles on this mess later, the Kubota approved way to make this work is to make the Land Pride 3rd function essentially removable with quick connects on the ends of the hoses, and attach the appropriate fittings to the hoses to power the 3rd function kit from the factory BH70 hydraulic lines when needed. It works out fine after a few weeks of head scratching and 10 or so trips to the dealer and hydraulic supply house. So I ditched all the 3rd function fittings on the hydraulic supply and return to tank ports, mounted a quick connect to a bracket attached to the seat frame on the return line, and just plug in the factory backhoe return hose to the return line on the 3rd function, and the hydraulic power out for the 3rd function attaches to the hydraulic hard line for the backhoe. Clear as mud.
So about a year ago, I took my B2301 to the local (1 hour drive away) dealer to have a backhoe mount kit and plumbing installed, which took about 6 weeks. The plan was to share a backhoe with my father in law (also has a B2301 and lives down the road). Finally had the need to run the backhoe a year later, low and behold, the local dealer did not install one of the hoses. The issue is, the missing hose goes to the return to tank port under the seat of the tractor, which is also where my Land Pride 3rd Function return line goes, it needs a non factory fitting. The local dealer chose not to deal with the issue in the first place, and wants 85 + 140 per hour (minimum 2 hours) to send someone to come look at it, then again to come fix it, or I have to take another day or two off work to get it back to them and be without the tractor for who knows how long.
Inconvenience aside, this does not appear to be a huge issue, but I don't know much about hydraulics. Hopefully this isn't too confusing:
This is the diagram of the missing Kubota factory line (A in the diagram, connects to return to tank port). I have purchased the hose and associated parts (sleeve, couplers, etc) from Messicks.
This is the schematic of the Land Pride 3rd function plumbing. In this diagram, hose 5 connects to the return to tank port with fitting 4.
My plan is to use this 9/16ths hydraulic T and nipple to attach the Kubota factory return line, in between the Land Pride fitting 4, and hose 5.
The local dealer did install the lower hose from the lower distribution block. But the hose is not routed according to the instructions. It comes out of the block, and back into it with hard line shown here (010) It's been like that for over a year, no issues. This is where the hose from the return to tank port is supposed to be hooked up according to the diagrams, while the line coming out of the block is supposed to hang unconnected. It appears to me, that if I routed the hoses this way, it would probably bypass my 3rd function valve. Given that there have been no issues with the lower hose as it is, I'd probably just let the return to tank line hang loose instead.
Does the Tee idea seem right?
Do I need a one way check valve or similar to keep fluid from flowing back up towards the 3rd function valve?
Does the hose routing cause a problem?
If this doesn't check out, my other idea is to either have a quick connect fitting installed towards the end of the 3rd function return line, or change the fitting on that hose to the same as the backhoe fitting, and disconnect it form the 3rd function valve up front, and run it all the way back to the backhoe return line, but that is pretty inconvenient to do. Obviously I wouldn't be using the grapple up front and the backhoe in the back at the same time.
