Thanks...yes, I was very fortunate to catch it. I was doing great, except running out of energy at times. I'm recovering very well, & looking forward to getting back to the tractor restore!!

Hi mayorbob,
Glad to hear you're ok, I'm sorry about the medical problem and hope this is solid cure for the heart thing! A guy never knows what's around the corner, but it's also nice to find that you have found out more about your machine and that you are sharing it all with us here on the forum. I've got some more stuff that I've been doing for my 530; like building a fork lift for the loader arms. You take care of you and we'll be sharing more here, Stan.

Stan,
You've done an amazing job on your Case 530CK. I have a 64 530CK, also with the Model 32 Backhoe. I am reportedly the 3rd owner of the piece of equipment as the last owner said he bought it from a city that had bought it new.
I bought mine to help in the building of a new house. It's not going to win any races or beauty contests, but it works pretty good.
The biggest downside is that I just replaced one of the Swing Hoses and got about 8 hours of use before I blew one of the Bucket Hoses.
Somebody along the way has not been very kind to the Hard Lines and they're bent in places they weren't originally.
I guess this time while I have the Backhoe off, I'll double check all the hoses and replace all that are suspect.
Do you have any advice for getting to the connections between the Bucket's Hose Connections to the Hard Lines at the base of the Lower Boom?
Thanks in advance!!
Dean

OK Dean, I'll give you some info. about your question tomorrow, I'm too tired tonight to type out an good reply, thanks, Stan.

Stan,
In regards to my previous question, I hope I'm gaining ground. I can barely get wrenches on the fitting, but I have no room to turn them. I am expecting delivery on a set of Crow Foot Wrenches today, that I hope will work around my clearance issues.
One other quick question if I may. All but one of the lines to the Backhoe Boom and subsequent cylinders appear to be 1/2", with the exception of what appears to be 3/4", to Boom Lower. This one Hose and Line is also the only one with the 3/4" JIC fittings and a larger line at the Backhoe Control Valve assembly.
I'm new to actually working on hydraulics and find it odd that only one line in a circuit would be larger than the other.
Do you have documentation calling out the size of the various lines and Hoses?
Again, your experience and willingness to help is greatly appreciated.
Thanks in Advance,
Dean

Hi Dean,
I知 back, a little late however, but here痴 a stab at answering your questions:
You asked; 電o you have any advice for getting to the connections between the Bucket's Hose Connections to the Hard Lines at the base of the Lower Boom?
Well Dean, I had a little easier condition to replace my hoses than you are dealing with, first, my whole #32 hoe assembly was torn down and apart which meant I didn稚 have to deal with the adjacent couplings and hoses and I could lay them in one layer at a time, that made it easier to deal with the particular ones that you are asking about. I致e included some pictures that I took at the time to show you how they lay in clean and fresh painted condition. You have to have the hoses loose from the boom to get a wrench into position to really loosen or tighten them correctly. There are clamps that hold each pair of hoses, boom, dipper (some refer to this as the stick or crowd also), and bucket. I had to fabricate a separator clamp for the hoses at the rear of the tower to help hold the hoses in position and that does help in keeping the hoses separated as well as keeping them from chaffing. Mine was missing when I restored my 530. As to my advice, if it were my machine and in an already existing assembled condition, I would drop the boom, take the clamps off of all the hoses so that you can pry them away from each other, then you can get to each fitting with a wrench to exert enough force to both loosen then tighten them later with new hoses. I think a guy would just have a terrible time trying to thread on the fitting while it is still being held by a clamp. Also, I never had good luck using crows feet wrenches on my fittings, they never would allow me to apply the necessary force to undo or properly tighten the connections. Maybe you値l have better luck than me but for my money I had to have the ability to get on the flats of those fittings with an end wrench.
Right hand dipper hard line and flex line.
Left hand dipper hard line and flex line.
Outer lines (dipper) inner lines (bucket)
At bottom center of picture you can see bucket goose neck hard lines and flex lines.
All hoses to show the stack, bottom hoses are connected to the dipper lines, the middle lines in the stack connect to the bucket lines and top stack connect to the boom.
Just another shot of the hose layout.
I include this picture to show how the stack of lines looks as they pass through the clamp.
Here is the pattern and bar stock that I fabricated my hose clamp from.

Here again I致e included a couple of pictures of my #32 hoe and an explanation, here goes:
You can see from the first picture that my valve box has the boom, dipper and bucket as all the same size. The stabilizer cylinders and swing cylinders are both a smaller size hose, I don稚 think either cylinders need a higher volume hydraulic than the sizing you see and only the working cylinders of the boom, dipper or bucket. I could be wrong but I think that the larger volume and size of those lines would help in cooling the fluid in those cylinders.
Ok, this is my configuration without hoses attached so that you can see the size of the fittings. The outer right and left valves have smaller fittings as do the center right. The center right corresponds to the swing cylinders and the outer right and left are the stabilizer valves (sometimes called outriggers). Just inboard from the outer left stabilizer valve is the bucket valve, next, center left is the dipper valve and on the right side of the swing valve is the boom valve. As you can clearly see they are all the same size.
I included this picture to show you the arrangement of the hard tubes and what goes to where if you wind up disassembling your line to replace them you would have a diagram of their place. Now, I took the time to refer to my CASE parts manual for the #32 backhoe (1974) edition for the OEM sizes for the hydraulic hoses and found some confusing information. First they state that the hoses for all three functions; boom, dipper, and bucket are 1/2 inside dia. hose with JIC fittings on each end, but when I inserted a 5/8 dia. round stock in that same dia. it fit. So they are calling for 1/2 I.D. hose but it痴 closer to 5/8祢.D. Also, they are specifying the bucket hose at the upper end (where the hose connects to the cylinder hard tubes as 3/4 hose and I am confused as to why they specify a ｾ line at the other end of a ｽ down below. Anyway, that痴 what the parts manual calls for but I think with mine, I used all the same size I.D. lines at both ends. I hope I haven稚 confused you too, but probably ask the guys at parker hose or wherever you purchase you hoses why the dimensional difference.
Finally, I would say that all of the lines in the boom, dipper, and bucket are the same dimension ｽ and the lines running to the swing and stabilizer cylinders are a size smaller, at least the fittings are smaller. Also, the line coming from the pump is the largest which attaches to the bucket control valve body then is distributed to the backhoe via what looks like ｾ I.D. lines. You asked good questions and I hope this helps. I had to do a lot of research on my own when I worked on my restore project and it was hard to find a central information center for anything on these old dinosaurs! Hope this help you and I知 sorry for the delay in answering this question, Stan.

Whew...almost two years later, and I am finally able to try to finish up the work on my 530 gas. I rebuilt the hydraulic pump, & it is all back together (well, almost). I need to find some pictures of the fittings and wiring under the gas tank. I found a used dash to replace the horribly old/worn-out original, so I'm hoping I have all the wiring where it should be. I have bypassed the governor & have solid lines to the carb & choke. The throttle linkage was absolutely worn out, so I removed that linkage. Can anybody give me a link for pictures from under the gas tank, & maybe electrical wiring. I haven't found a really clear schematic for the wiring yet. Thanks for any/all the help. Bob
Hey Stans,
Did you ever figure out the power steering? I picked up a 530ck Backhoe as well, and the wheel is almost impossible to turn. Certainly seems like something is binding up, and the power steering definitely isn't working.
I'm trying to find some issue on the single cylinder power steering system, and like you, can't find much info about it.
