1963 Case 530CK Backhoe/Loader

[wmonroe]

Wow good that you caught it before a heart attack. Good luck with the recovery!

 

[mayorbob]

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!!

 

[stans1]

Goodness, it is a year later, so guess I'm late to responding. Medical problems have made me set this aside for awhile (like open heart surgery!...but I'm doing good in recovery). My serial number puts it in the middle of 1962. We'll see... Bob

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.

 

[DeanMurphy]

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.

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.

Hi NBraun,



Welcome to the forum! Not sure what you mean by: did I get the power steering figured out? I never had trouble with my power steering.... However, another member (mayorbob) asked me if I could help him with figuring out his power steering. He posted pictures of his model and I had never seen that particular type before and could not give him an answer.



Post a picture of what you have and let's see if we can identify what your problem is. If it is like mine, there are really only 4 parts to the system besides the hoses and hard lines and they are: engine driven power steering pump, steering control valve, steering manual pump, and last but not least, steering cylinders. It may be as simple as one of the wheel spindles is bound up in the bearings and a quick test for that is to jack up the front end off the ground, undue both power steering cylinders at the connections to the spindles. If you can move both front wheels manually with the tie rod still connected with no resistance then you have at least isolated the problem to the power steering system and not a mechanical problem with front end.



Also, check your power steering fluid level. If you don't have any fluid or it is too low there won't be any power assist! Post a picture and let's see what you have. Thanks NBraun, good to hear a new voice.......

 

[NBraun]

Stans,

Not sure how I got that mixed up! I guess I was in a hurry and it was late.

I believe mine is the early steering, with one cylinder on the axle. I checked the fluid level and it was empty. With fluid in the reservoir, the steering has gone from basically impossible to just having to really muscle the wheel. So a bit of an improvement for sure. I'm not sure if I need to bleed the system of air, and if so, how to do that, or if there's something else I'm missing.

The tie rod ends are shot, which I'm sure aren't helping anything. I'm generally pretty handy, but without seeing a diagram of the steering system i'm having a hard time figuring out what to look for next. They really managed to cover up all the systems on this tractor!

 

[rScotty]

Nothing to add, just wanted to make sure this old thread is available in my personal list. It's fun to read.

I did a little more research on the type of 530 that you have and here is what I found on another forum and this guy seems to know a lot about the 530 and 530CK Cases. Now this information does not directly answer your question about what do about your steering problem, but it will give you more information as to where to start researching your particular model of Case 530. I am just copy and pasting from that forum the response:


1960-1966 Case 530CK

If you just want to get your backhoe home, lift up the loader and put a 4x4 across the front of the hood/loader support, to hold the loader up, then take a couple of chains and come-alongs and pull the hoe up closer to the tractor so it doesn't drag on the ground when you go up the ramps. Then, back your trailer up to the machine and winch (or push) the 'ol girl up on the trailer.
Once you've gotten the loader bucket and hoe bucket off the ground at a reasonable height, if there's air in the tires, she'll roll right up on pretty easy. That's how we've moved dead hoes in the past.

As far as modifying your injection pump, don't. Just leave it as it was - no need to try to add any valves to it, as it's unnecessary. Leave well enough alone and don't add or subtract parts. Just repair what ails it, put it back on, and get your tractor running and operating again, as that's what matters.

I'm curious, but do you know how long your backhoe has been sitting, and more importantly, WHY it was parked?
I ask because you may be in for some more surprises if and when you get it up and running!

Based on your pictures and Serial Number that you posted, YES, that is a "true" 530CK that you have there.
They were built from 1960 to 1966, and then replaced by the 580CK.
The S/N of 8217566: dictates that your machine was in fact built in 1963.

530 CK Serial Numbers:
1960: 8160001
1961: 8168801
1962: 819001
1963: 8208001
1964: 8229001
1965: 8253501
1966: 8279001


Anyhow, not that you asked for a big long storybook explanation, but I figured I'd take the time to explain a little about the 530 and 530CK's - for the archives and for the others that visit this site's benefit. Heck, I even included some nice pictures. So, read on if interested.

When looking at a Case 530 T/L/B, if you actually pay a little closer attention to some pretty obvious details when looking at them, you will notice some substantial differences between a 530 and a 530CK, which I will go into a little more detail below.

On the Pre-1960 Case 530 Tractor/Loader/Backhoe (with Model 31 loader & hoe):

The front-end loader design was actually the most "in-your-face" obvious difference.

1.) They did NOT have a hydraulic self-leveling bucket feature.
2.) The loader's dump cylinders attach directly to the loader arms and to the bucket, like most conventional Ag loaders use.
3.) The front frame structure of the loader's frame is different. The 530 (model 31) loader had a massive "brush guard" if you will, built into the front "wrap-around" style loader frame. The loader framing ran horizontally and relatively parallel with the ground.
4.) The 530 T/L/B was still very much an AG tractor with the front hood tinwork constructed with the infamous Case "eyebrow" hood & headlight design. This required the front loader framing to be a "wrap around" design for strength and for a lower mounting support.
5.) On the hoe, you'll notice the boom swing cylinders are mounted up relatively high up, above the main pivot points and on either side of the boom "out in the open", so to speak.


Below is a PIC of a Pre-1960 Case 530 with a Model 31 loader.

On a 1960-1966 Case 530CK (with Model 32 and later loaders & hoes):

1.)There is a short vertical hydraulic cylinder used for "self-leveling" the bucket when the loader is raised and lowered. It is located on the right side of the loader mast, just ahead of the loader control valves.
2.) Self-leveling bars and such are used and work via a pivot that is part of the loader arms. The dump/tilt cylinders mount to the loader from (and pivot at) the sides of the barrel, and not from the cylinder end. The rod end of the cylinders mounts directly to the loader arms, and NOT to the bucket. This setup allows for the self-leveling to function, as well as the ability to curl the bucket back further, thus holding more capacity in the bucket when digging into a pile.
3.) The "newer" style CK loader frame (the Model 32 loader) is bolted to the front sides of a heavy steel "wrap around" front nose structure that is an integral structural part of the "nose" of the tractor, utilizing the tractor's front structure for part of the loader's structural integrity. You will also note that the loader's side frames run on a DIAGONAL from the upper part of the front of the tractor, to the lower front of the rear axle.
4.) Gone was the old Case "eyebrow" headlight design, in lieu of the new heavy steel wrap-around piece that allowed for the loader frame to be bolted up to it.
5.) On the hoe, you'll notice the swing cylinders are mounted down low near the ground below the hoe's main frame, and near the lower boom swing pivot point.


Below is a 530CK with a Model 32 "hydra-leveling" loader.

As you can see, there are actually a LOT of differences between an earlier Ag tractor based 530 T/L/B and a 530CK.
The basic tractor design, the loader design, and the hoe designs were all quite different.

(Unfortunately, I was unable to find some good backhoe pictures to post at this time. Perhaps if I find some, I will add them to this posting.)

530CK transmission options: There were 3 different transmission types offered in a 530CK.

Option #1:
Transmission: Dual Range Shuttle

Type: mechanical shuttle

Gears: 8 forward and reverse

Comments: Four speeds plus reverse with two ranges (low/direct) and a shuttle lever. Torque converter was optional. Torque converter can be locked out by engaging direct-drive mode To engage direct-drive the lever is pushed down. The torque converter will be automatically re-engaged when the clutch is pressed, or can be re-engaged by moving the direct-drive lever up.

Option #2:

Transmission: Case Triple-Range

Gears: 12 forward and 3 reverse

Comments: Four speeds, plus reverse, in three ranges (low/direct/high).

Option#3:

Transmission: Standard torque converter/direct drive, NO shuttle.

Gears: 4 forward and 1 reverse

Comments: Four speeds plus reverse. Torque converter was optional and could be locked out by engaging direct-drive mode.


The 530CK was the first of a "revolutionary" change in true T/L/B design, that is still the basis of every Case backoe built today.

Another thing about T/L/B's to keep in the back of your mind is the fact that many things get changed over the years, especially when the machines were used daily as construction machines and also when they were much older and worn out and owners without deep pockets were looking for the cheapest and/or easiest way out to repair their old worn out machine. Hoes and loaders get swapped around when possible/practical, engines get swapped, etc. From what I've seen over the years, the HOES tend to be changed on the machines more than anything. Typically, if a loader and hoe model are the same on the machine, then it is likely an "unmolested" machine. However, that is not always the case.

Regardless, be sure to always pay attention to the model & serial number tags on your loader, hoe, AND tractor. Yes, even on the later CK's.
Tag ID's are very important on equipment, especially the old Case's.

Andy



That style of steering was used on utility and loader-tractor loader backhoes until sometime in 1964 when they changed to hydro-static steering with the twin cylinders

I hope this help you with your research NBrawn, cheers

Hey Scotty,

Glad to hear that you enjoy the thread, hope that previous posts were entertaining. It's kind of interesting, the different steering types that were introduced with all the different models of Case early backhoe/loaders. Some of the questions that others bring up have educated me as well.

 

[xkross]

Hi everyone, I just purchased a 1966 Case 530CK backhoe. It has a model 32 loader and hoe with the hydra-lift system. It was in a junk yard and I paid the fellow $1000 for it. It came with 2 extra hoe buckets. There was 3 4" maple trees growing up through it, so it had been there for a while. The tires held air so it wasn't to bad to load. It is a 4 cyl diesel and I can rock the engine back and forth so it is not stuck. The engine oil and coolant is clean. I pulled the injectors, which were coated in carbon, and one of them had started to come apart, which may be why it was retired. It has the old style injectors. Checking around on the web, it looks like common repair parts are going to be hard to find. I have the service manual and parts catalog, which is a big help. What I haven't found is a listing of the hoses and fittings other than the Case part numbers. Does anyone know of a hose listing that uses the more common numbering system for hydraulic fittings?

 

[rScotty]

Are older 580 Case parts that hard to find?? I nearly bought a Case when I was looking for a used backhoe. I've two neighbors who have later model 580s with cabs and they argued that I should find a Case like theirs. One thing they said really made sense was that the 580 Case was designed to be more friendly for an owner who does his own work - as we all do - than was the JD310 or similar size Cat.

In 2014 I looked at a real clean 580 Super L & sure liked it, but for some reason ended up bidding on a Cat 416D before actually buying a JD310SG.

The 310SG has been good in spite of high hours. Great local dealer and parts easy to get.

Hey, I'm going to be replacing some lines on the hoe of my 530CK and was wondering if you could help me out. I'll take pics when I can but there seems to be a LOT of extra line in the base of mine, and I was wondering if I should try and bypass the extra or just tie it up better than the last owner. Mine doesnt seem to have a pass through clamp but instead passthrough fittings in the hoe's base frame. Mine also has the outward facing swings.

 

[Dope]

Iv got a 1962 case 530ag with the ck backhoe setup on it i have 2 major problems one I can't find the right steering assist ram hear is a picture of the one I have the other problem is it's a shuttle shift I'm not sure of my problem but it won't fully engage or disengage if you have any suggestions on wear to look to fix that or any idea wear to get the steering ram i would appreciate it look forward to watching the progress on yours
Thank you for your time

I was told by the previous owner that mine is a 63, but the identification plates are missing on the tractor and loader. The identification plate on the backhoe says it's a 31 model however instead of a 32. I have double piston steering. I also did find the engine serial number plate. I have pulled the hoses out of the boom arm (without unhooking anything) to show how much extra hose I am seeing.
