P/S B7100/7200

[amitysanimal]

The only thing that runs off the main pump is the 3pt hitch. The FEL has its own pump and the BH has a PTO pump. I am thinking that when I do use the 3pt hitch, I'll just stop to raise it or just not steer while raising it.

Also, where would I run the return line too?

There is a fitting coming out horizontally from just under the seat that is plugged of. is this a pressure port or a return?

And I have the trans filler hole, I have seen a hose running into there on some other B7100. (Can send a pic if it helps)

Could either of those be used for the return?

Basically there is no return line. The pressure line runs through one side of the block, through the power steering valve, then back through the other side of the block. The outlet under the seat, at least on my 7100HST, is an auxiliary outlet, one way, that is controlled by the directional valve under the front of the seat. Oil pressure is only used by the steering valve when you are turning, at least the way I understand it. I am trying to attach a PDF file with a parts breakdown for a Kubota LA352 loader. Page 17, I think, shows the hydraulic block that you will need.

I think my third picture on my original post shows the hydraulic block front cover plate that provides for access to the pressure side of the hydraulic oil supply.

P.S. I have an auxiliary cylinder I use to raise my mid mower that runs off the second outlet under the seat. I turn the valve one way to raise and lower the mower, and then the other way to run the 3 pt. hitch. The return from that line runs into a 'T' fitting that runs the oil back into the hydraulic oil filler opening.

OK, sounds good. I'll go to the Kubota dealer tomorrow and see if I can get that block, or just drill/tap mine.

Thank You,

If I recall correctly, the outer block you intend to drill and tap is in fact a bypass. So you must figure out a way to also plug the horizontal connecting passage between the two existing ports for it to be effective. My guess is that this passage diameter is probably the tap drill size for the plug on the end of the block.

I AM SORRY I HAVE NOT POSTED PICTURES. SOMEONE WANT TO TELL ME HOW. MY STEERING IS A BOLT ON WITH NO WELDING OR CUTTING THAT TAKES ABOUT TWO AND HALF HOURS. TWO BRACKETS NEED MADE, WITH A TOTAL OF TEN HOLES DRILLED. IF EBAY IS WATCHED CAREFULLY, THE COST CAN BE WAY BELOW $250. A VERY SIMPLE INSTALLATION WITH ITS OWN HYDRAULICS. CAN NOT UNDERSTAND WHY PEOPLE PERSIST IN TRYING TO ROB THE HYDRAULICS ON THEIR TRACTORS.

I don't want to mount a pump on my engine, I don't want to remove my side cover and have that pump sticking out. My main tractor hydraulics are rarely used, I have my BH on 95% of the time, no need to lift the 3pt hitch much, so not sure why it would hurt to use the hydraulics I have readily available.

WHAT ARE YOU GOING TO USE FOR A DRAG LINK? YES THE PUMP STICKS OUT, BUT YOU STILL HAVE YOUR SIDE COVER. PART OF THE SCREEN ON COVER IS REMOVED. YOUR EXHAUST STICKS OUT ON LEFT SIDE AND YOUR AIR CLEANER ON THE RIGHT SIDE UNLESS YOU HAVE BEEN ABLE TO STICK THEM INSIDE OF PANNELS.

Here's the link for the instructions for posting pix on this forum. If it doesn't work out please get back for further tips because I for one would like to see what you have come up with.

THANKYOU FOR GIVING ME THE LINK, BUT I HAVE SPENT MORE TIME TRYING TO POST A PICTURE THAN IT TOOK ME TO INSTALL THE P/S. I AM GOING TO HAVE TOGET SOMEBODY TO HELP ME. LAST NIGHT I TRIED TO SEND ELSIE 71 A EMAIL OF THE TRACTOR. IF HE RECEIVED IT, MAYBE HE WLL POST IT FOR YOU. OTHERWISE, MAYBE THIS WEEKEND I CAN GET SOMEONE TO COME TO THE HOUSE AND SHOW ME WHAT I AM DOING WRONG. BY THE WAY, THE PUMP STICKS OUT PAST THE HOOD 2 INCHES,WHEREAS THE EXHAUST STICKS OUT ABOUT 5 INCHES. THANK YOU.
