L2501, 2017, adding BH77 backhoe

[OrangeColoredTractor]

Bought a barely used BH77 from local Kubota dealer, just installed the frame kit, all went well, but ran into a few areas. First if the hydraulic hoses, I remove one from the valve unit down to the ports below, install kits unit from the control valve to the back, then the other hose goes back to the block under the floor. The flare, it screws on but I can see the seal angle is steeper, does it form to the valve block (under floor), it looks like hard steel to me and dont want to cut into seat.

Also, the rear hoses, no way to loop them. I cant even manually screw them together to form a closed loop, so hoses are in place, but not hooked up.

I take tractor to dealer next weekend to hook up my backhoe. But as of now, not ready.

Quick couplers is what I want, what size is the threaded ends?

First image, original hose with green tape is the one I should remove and that is replaced by one that goes to the back quick change coupler.

Next image, see the potential loop, one end, male threads on hose, red camp, other end is a clear plastic cap, that is the other end. I assume quick couplers that I can look when not in use.

Final image, BH77 mount all in place, no extra parts. I know I need to remove rear brace between fenders before getting backhoe.

Anyone else run into this??

The dealer installed mine, so I don’t have "1st hand knowledge" of the installation process.

I get back today, and will take some pics of my set-up and post them.



Good choice on getting a 77.

I am a Yuge fan of mine. Best 11k I ever spent.

The connections to the outlet block under the floor are all JIC 37° flare fittings and the hoses have matching female swivel ends.

The male threaded ends on the backhoe connections are 3/8 NPT. Make sure you get the correct size and series quick couplers. I am going to GUESS they are 3/8" ISO 7241-B

Yes, excited to get the hoe. I got it used, I mean barely used, paint barely knicked on the bucket, no worn paint in operators area. Suspect someone bought tractor, didnt use it, traded it in and new buyer didnt want the backhoe. Frame kit came with seat pedistal and seat, so I guess I have a spare.

I got it for $6500 used, this is with frame kit.

OK, thank you very much for the ISO numbers, found everything I need but cant get them in time before sat so lets hope the Kubota dealer has a set on hand, sure they do.

Here is a few pictures, my truck in background waiting to be loaded with large crate for frame kit.

Old Hokie, thank you very much for that info. That JIC 37 degree flare, is that pretty much all the fittings? That is what was different, hose at block vs line from kit, the flare looked steeper on the new hose, but flange nut fit.
And the 3/8" ISO 7241B does look perfect too. Is there a preference, ie which side from pressure vs return for male or female coupler. I would imagine the larger female to be pressure. I know with the poppet end they both seal. Obvious, it will need to batch the backhoe too.
