7510HSD rear hydraulics

[pemad]

Question for you 7510 or 7610ers.

I want to hook up a rear hydraulic line to run an implement.
Need to know where to T the lines into for delivery and return.
I see where the loader lines hook into and was wondering if I could just T off these.
There are 2 in the front and 1 that comes from the back.

Thanks for your help in advance.

Others will have more detail and there are alot of previous posts on here but essentially you need to come out of the power beyond port on the loader valve to the inlet of the new valve and then you can tee the new valve's return to the loader's return.

Kevin

You cannot tee into the hydraulic pressure lines on your tractor. The only line that can be teed into is the return to tank line. All aux valves must be open center and must be connected in series with the loader valve and 3pt, the easiest way being between the loader and 3pt. For optimum performance your aux valve must be configured for power beyond.

There are plenty of B7510 users here who have added remote hydraulics. Do some searching and you will find them. I have posted at least a several dozen or more times the instructions for plumbing an aux valve to tractors like yours. It's not hard and anyone with any amount of mechanical ability can do it.

MadReferee,

Thanks for the reply.
I did some more searching and found a lot of posts on this subject.
I now understand what you mean by in series.

Here is what I am thinking as I only need the lines, as the remote on my attachments are power beyond.
1) Remove the line from the block that feeds the loader valve.
2) Run a new house to the back of the tractor with a quick conector in the back.
3) Run another hose back to the loader valve.

This way I am in series and all should be good to go.

Thanks

The one thing you have to keep in mind is that if you ever start or run your tractor with nothing connected to the rear QD to make a complete hydraulic circuit (pump to implements to tank), you will immediately destroy the hydraulic pump. It can get rather expensive rather quickly if you fail to have a complete circuit.

What type of attachments are you talking about? Log splitter? Backhoe?

I use it mainly for my CadDigger 3pt backhoe.

Prior to purchasing this tractor (yesterday), I had this type of setup on my BX2200.

I bought all the parts that were needed for the BX22 and I was fine. I just made sure that the lines were always connected prior to firing up the tractor.

Had one mishap where the coupler did not lock in and when I fired up the BX the tractor started boging down. I immediatly knew something was wrong and shut her down. Just reset the coupler and I was back in business with no damage.

Do you have another suggestion that is safer and will not self destruct my pump in case the line is not connected?

Thanks,

Summarizing what I've read in the threads on this subject, hose from FEL power beyond gets disconnected from hydraulic block and connected to "in" port on remote. The power beyond port on the remote then goes back to that port on the hydraulic block. The "out" or "tank" port on the remote gets connected to a new tee at the tank where the "out or Tank" port from the FEL is connected. And the remote must have an "open center" type valve. And a remote is better than just having a "power beyond tap" because you can bungee it open if you use it for a splitter or backhoe or use it normally for a dump wagon or hydraulic top link. I'm applying this concept to a Kubota B7500. I know I'm just regurgitating everything you've already said, but if I have this right please let me know. Also, can anyone point me toward any online sources for the correct type of valve and hoses. B7500 pump is 4.4GPM. Thanks!!!!

Update, I found PSDawg's thread on his remote and parts list. His B7510 would match up to my B7500. Assuming I've got the rest of the connectivity down correctly, I should be good.

That is correct on all counts.

For a valve, the Eaton-Cessna series from Surplus Center is the perfect choice. It's compact and lightweight and will fin in the area between the ROPS and the seat. Several members here have used them. Search for posts by member 8561 as he installed the 3-spool Eaton-Cessna on his B2410.

The Surplus Center part numbers are 9-4501 for the 2 spool version and 9-4503 for the 3-spool version. The power beyond sleeve is part number 9-4504-B.

Ron,

I used psdawgs post when I did my B7500. Everything came out great. I did have to muck around a bit with some of the fittings and ended up changing a few from his list when I ordered. It actually takes much longer to plan the job than it does to do it. Going over all those fittings and making sure you have everything you need is a real pain.

I will try to take some pics to post.

Mike, Thanks!! I'd like to see those. The only thing I would want to change is to at least use 3/8 on one of the working port sets so if I use it for a splitter or something, I'll get the full flow. I'll have to figure out what to change to fit a set of 3/8 QD. I'm thinking angle the inside set 45 degrees.
