530-535 power steering

I have a Ford 535 backhoe which I believe is based on the 530-540 chassis. I have a power steering problem and need a diagram, page or pages of the service manual covering this system. I will pay for copies of the material I need, any information or leads would be appreciated.

The 535 was an industrial chassis tractor that replaced the 4500.

Here is a link to the parts site with the front axle and steering section for that model selected:

What is the problem with the steering?

Looks to be the same steering setup as my 4500 that is almost the same as the early 5000.

Can't believe the fast response I received from Destroked and Sean in PA, Sean came thru with just what I need, exploded drawings. My machine is missing the yoke/clevis end and pin of the steering cylinder shaft/rod, but the parts drawing doesn't show the shaft/rod in two pieces. I need to find a source for the parts or part that I need, new or used can anyone help?
Thank You

The parts site shows that rod with the end for the clevis pin all as one piece as you say.

What does the end of the existing cylinder rod look like on yours? Is it threaded, male or female? Or does it look like it was cut off?

The part number for the entire rod with the end is C5NN3A747A. If you do a Google search on that part number you will find many places selling replacement rods, including a couple of sellers on ebay. This site doesn't allow me to post the URL for the one on Walt's site, so replace the "link_disallowed" in the first link below with w a l t s t r a c t o r s . c o m (remove the spaces):

Pulled the grill off to look at the cylinder, the 535 is quite busy there as the hydraulic pump is mounted down there forward, the supply and return lines and the pump drive shaft along with approx 40 years of collected dirt and hydraulic fluid have filled the area. The shaft/rod is exposed and more or extended to the very front of machine just below grille.

I can see the shaft, it is against the forward portion of the machine the but not the actual end nor can I wiggle my pinky completely around the end, however the end is not sharp and is squared off like it was machined that way. It appears that the cylinder is active as a rubbing wear pattern is evident on the front and adjacent side. What I do not see is an attachment point for the pin.

I am going to have to clean out this area but I really can't see how the cylinder has an attaching point at that end there does not appear to have a boss or ? The exploded drawing are good but lack point to point assembled illustrations.

I have a guy in here right now hauling out 50 cubic yards and have to stay with him plus run errands, will the move machine away from clay where it is sitting, so I can pressure wash I hope the crud off. Hopefully later today!

Thank you for your input!

Sean
Thank you very much for the last response, I have cleaned the area as best I can under the crowded circumstances and still can not make out
what I have with the shaft. Have reviewed the links you supplied and it looks like I will need to replace the shaft and while at it replace
the seals. When I pull the cylinder out I hope to locate the mounting point for the shaft end.

Thank You for your help!

Sean;
I am back on the backhoe again, have a number of projects inside and outside working at the same time. Have a vintage car that now needs a new rebuilt and installed so we can leave 6/15. Trying to get my shop site graded and now need the backhoe to work with the guy doing the grading, I can not steer the thing with a large load of rock ( these are very large rocks one per bucket load)so I need to get the steering operating. There is no end to the cylinder shaft, I can not find any place where the end would terminate. If I could locate and identify this (missing)component, I would try to pull the cylinder out replace the shaft and install the rebuild kit. May have to locate a New Holland dealer and see if they can help me out.

The rod is no longer available, and neither is a direct replacement cylinder. If I were you I would call around to tractor salvage yards to see if one of them might have a used cylinder.

The end of the rod should attach to a tab attached to the right side of the front bolster. Part numbered 18 in the parts drawing at the link belo. If you use the slide control in the bottom left of the drawing to zoom in and then drag he picture around to see the part of the drawing you're interested in, you'll see the dotted line going from the pin(17) at the end of the rod going to the tab(18) on the side of the bolster:

Sean;
I got into really digging around in the mess left after I tried to pressure wash that very crowed area that contains the PS cylinder and the systems Hyd. pump along with all the supply & pressure lines. Started to dig thru the dirt, dust and oil & fluid brownie that was an inch thick in spots. After scraping and digging I was able with a mirror to finally see a threaded member that is actually a male clevis that must have screwed into the cylinder shaft. It was held in place by a heavy pin that threaded up into the large casing that makes up the front lower portion of the tractor the front axel pivots from. I will attempt the clean up the male threads on that end. if I can get it threaded into the shaft I will test the operation. I really appreciate you interest and assistance in my quest.

Sean;
I spent a great deal of time trying to collapse the ram/shaft back into the cylinder so I could try to screw in the male clevis end. I was able to push about 1 1/2" back into the cylinder then it stopped dead. I removed the return and pressure lines, disconnected the linkage to valve on the cylinder, pried on the shaft end with a good sized bar, moved the valve linkage back and forth without success. I don't know if there is an obstruction in the cylinder or ? If there is an obstruction I don't think there is enough room to remove the cylinder from it's location without the shaft/ram being pushed all the way back in, any suggestions?
Steve

Steve,

The control valve for that cylinder is part of the cylinder itself. If there's nothing pressing on the linkage then the control valve is probably centered and is not letting the fluid flow out of the cylinder when you are trying to push the ram into the cylinder.

Here's a link to the exploded diagram for the cylinder:

http://partstore.agriculture.newholland.com/us/parts-search.html#epc::mr1246709ar259246

The control valve is the spool numbered 18 in the diagram. it is moved by the link (part numbered 38). Try moving that link while you try to compress the ram. It should open the proper side of the valve if you move it in one direction or the other (push it in towards the valve housing or pull it out away from it).

Which way do you have the wheels turned, the ram attaches to the bolster and the cylinder moves with the steering linkage. If the wheels are turned all the way to the right it moves the cylinder out giving you the most working room and max ram extension.

Sean and Destroked;
I had thought the control valve was the hangup after I pulled both lines from the valve. I did disconnect the linkage to the valve and by myself and pushed the valve connection yoke towards the rear of the machine while trying to pry the ram back into the cylinder. This is no small task by one's self, but as I reported the ram/shaft appears stuck. Will try again tomorrow when I will have two additional mechanical hands that can assist me, maybe with 4 hands and 2 heads we can get it to collapse. I really need it as far in as possible so I can try to clean out the debris internally prior to trying to thread the male clevis end into place. If for some reason this does not work for the 2 of us, I may have to try to pull the valve apart while in the chassis. As usual appreciate the input and helpful tech sheets.
