1963 Case 530CK Backhoe/Loader

[stans1]

It must be the leveling cylinder you mentioned. I just assumed there was the same cylinder arrangement on each side.

Thanks.

I think you are correct when referring to the older 530CK's. They had a different configuration on the loader portion; the lift cylinder for the arms and then the bucket dump cylinder, which had a direct connection between the arm and the bucket. Later 530CK renditions had a multiplier arm that pivoted from the arm and the trunnions of the dump cylinder. This had the effect of increasing breakout and prying force with the bucket.


As you can see from this photo, the two arms that connect with the trunnions about mid cylinder, those arms are not on earlier CK's. And you can see also in this photo the leveling cylinder that is almost vertical above the lift cylinder, Stan.

As I said earlier, here is a post on the rebuild of my 12" bucket. It had worked OK, but the bushings of course were worn and especially the pivot bore was really in bad shape. And as you all know, a new bucket is really cost prohibitive and used ones are sort of hard to find. This bucket had worked well for me, so I thought I would refurbish it and hopefully make it more functional. When I had cleaned it all up I found that the pivot bushings were not only worn but someone had tried to weld them in because the bore was so wallowed out that the bushing would not stay in place. The bucket flange that has the pivot bore in it is only 3/4" thick and not really wide enough to contain the pressure placed on it in the digging process. So the bushing was bound to fail.


In this shot you can see the new boss that I machined and tack welded to the bucket flange. I aligned it with the bore before tacking it with an internal sleeve that I also machined. That way when I made the new bushing it would be retained by twice the surface area as the original 3/4" flange, the new thickness would be 1 1/2" which I thought would stand a better chance of resisting the wear that a backhoe exerts.


Just a closer view of the new boss and pin washer to the side. I made larger washers to help retain the pin in place. this also gives you and idea of the final alignment. When you don't have a line boring tool you have to be inventive to still maintain the concentricity of the bore.


This is one of the many alignment bushings and devices I had to make to align bosses and bushings. I used 1" acme threaded rod stock to make the bushing puller-pusher. Regular all-thread was not nearly as manageable as the acme thread. It seemed to me that the amount of effort needed to turn the acme nut for pulling or pushing my bushings was about 1/3 that required to turn a 1" all-thread nut.


Here is one of the bushings in place and of course 2 times longer than the original bushing.


In the far side of the picture you can see the new bushing installed and in the nearer view, the interior surface of the bore about ready to have the bushing pressed in.


I took this one to show how the pressing device looks when it's being used and in position. As you can tell, it's very important to keep the bores in alignment and with this view the alignment bushing is on the right hand side with the acme threaded rod inserted in the bushing bore and then you can see on the left side that I am pushing the bushing into position using a piece of 1" bar and the acme nut on the right side, that way I'm not pulling the flanges together to install the bushing. On the far outboard side you will notice that the nut has been removed and the bushing pusher is partially out of the bore, that's because the bushing has already been pressed into place.


Just a closer look at the in place bushing and pushing mandrel.


Just one of the alignment bushing.


And of course; the finished bucket. Even though I've been using the hoe a bunch now, writing up this post brings back a flood of memories.

This backhoe was lucky to find you.

Yeah Bob,

That's a great bunch of pictures that you took of your machine! After looking at your pictures that you posted of your steering system, I don't recognize any of the parts on your tractor. Check your serial number and check it against the known years for Case industrial equipment. You might try this link and see if you can find anything helpful: http://home.microtech.com/mikef/530CK/gas.php

Hope this helps, Stan.

Stan: Checked & rechecked, & my serial number, 8197411, puts me right in the middle of 1962. Is there a difference between 530 CK and 530 SL? Mine is an "SL"...& you are right, nothing shows the single cylinder and steering shaft like I have. Any other suggestion as to where to look? Bob

Bob, I did a little research tonight and found some interesting information on the 530CK at this site: jdemaris others,I have a few ? on a 53 backhoe - Case and David Brown Forum - Yesterday's Tractors A couple of the answers were good information about the whole series of the 530's including just tractors that were not configured as backhoes.

 

[mayorbob]

Stan: Thanks for the research. Interesting...shows me that I know what year my Case 530 is (1962) for sure, but what of my bucket, or backhoe. They do not fit the description I'm finding, nor do they fit my Service Manual. It describes a Bucket Loader 530, but I don't have the bucket leveling cylinder; ;

I'm still trying to find out what model Case 530 I have with the single steering hydraulic cylinder. Any information on that?

 

[stans1]

Hi Bob,
You know, after studying your particular machine, and looking at the loader set up, I don't see anything that looks like the earlier 530CK's that Case shows in their earlier literature........... For instance: the small links that attach to the loader arms on yours, which then link to both the dump cylinder and the upper loader arm is not something I've ever seen. Don't know if it's just an aftermarket configuration or some how a Case derivative. Have you talked with someone from Case or inquired at a Case dealership?

I've enclosed a picture that I found on the internet some time ago and saved, in the process of comparing all of the differences, in Case products during the start of my restore. I wanted pictures of any type and models that I could find. So, take a look at this one and I think you will see that the Case tractor for your year was completely different from the one you own:

Sure do appreciate the information. Can you recommend a dealer to talk to. We have one in Sunnyside, WA, about 35 minutes away, but when I went there to find parts, they had no idea what I was talking about. The bucket configuration is close, but not the same. Since my bucket & backhoe work just fine, I'm not worried about them. I am trying to get the power steering working, and the transmission working. I am in the process of removing the hydraulic pumps to have them rebuilt, then see where I go from there. I had a dealer in Auburn, WA, tell me that I had a regular farm Case 530, not a "construction king" model, but nobody else has known anything about that. So I keep asking. thanks again for your help.

Say Bob,
I didn't have time to really study your pictures that you posted, showing your whole tractor and the loader. After a closer inspection I noticed several items that don't match anything that I have seen but would, I think, indicate someone fabricated that whole loader arm, hydraulic cylinder, link, and dump combination or at least combined different year parts.

Now if you study the main structural arms (the ones that attach to the tractor itself), then follow the vertical arm (the ones that are your hydraulic fluid reservoirs) and look closely at the top of the arm you can see where someone has welded flanges on both frames. These flanges are the pivot points to long bars that extend down to what appears to be cast links that pin to both bars then dump cylinders. I'm assuming this would give more leverage during material handling. Anyway, that was the first anomaly that caught my attention, then I was studying the loader arms themselves and noticed that the welded flanges for the pivot point of the lift cylinders are very similar to the arms on the later 530CK's, not the older 530CK's. I'm not saying that this isn't OEM, but in all of the older 530's I've only noticed that the dump cylinders connect directly from the loader arms to the bucket and no extended apparatus to the structural arms. Also, look at your pivot hole or bore in the loader arm, just below the lift cylinder flange and notice there is a bore for the connection of those cast links and pins, well, I don't think you would ever find that bore in the older arms. Take a look at the picture that I posted of that restored older Case 530CK in my earlier post and you will see that there are no holes in the loader arms because the dump cylinders pin to the flanges on the arms and down to the bucket.

Finally, Bob, I don't think you are going to find this configuration in a Case shop manual. I could be wrong but if it were me I'd be looking to do my own repairs and fabricating the things I would need to fix or to maintain it. And as far as the steering configuration I guess I would keep trying someone in you area that might have a handle on it. I'm sorry that I couldn't be of more help!
Stan.

Stan (et all): Here are some pictures of the steering setup on my '62 Case 530 backhoe. View attachment 511517 - Here is the lower steering shaft U-joint: View attachment 511518 - This is the upper U-joint: View attachment 511519 - Hydraulic cylinder (single): View attachment 511520 - Cylinder connected to right side: View attachment 511521 - Power steering pump (near as I can figure): View attachment 511522 - Power steering filter (I need to find proper filter or replace unit): View attachment 511523 I'm looking for any pictures, illustrations, pages from shop manual, etc. My manual shows the dual cylinder setup, which has no relationship to mine. Thanks. Bob

Hi everyone I bought a 1962 case 530ck and I can't find any parts for this type of steering assembly i have only found 1 repare manual that even shows this steering setup I would appreciate any help i can get finding parts
Thank you

 

[mayorbob]

Been a while since I've posted about my 62 Case 530 restoration project. I'm putting the power steering pump back together...it had a chip out of the keyway, & the shaft was too hard to cut the keyway larger. So some JB Weld & hopefully I can get some use out of it before it totally destroys itself. Otherwise it looks good. I'm having the shaft in the COM hydraulic pump replaced...had to have one made. Bought a used pump, but it had the same wobble as the original. Both shafts were evidently bent (occupational hazard on a 530?). It should be ready next week. Medical interruptions & work have slowed me down...but it's been way too hot to work on it, as it is outside on my property. So perhaps I'll get it back together. Replaced the check-ball in the hi/low shifter, & now seems to work. Slow going, but I'm "going"...

 

[stans1]

OK Andy, here are a few pictures of the main hydraulic lines to and from the spool valve box on the backhoe and tractor:


Both lines are, high pressure and are 5/8" ID. I believe. In this picture, the line that is crossing underneath is the line and attaches on the right side of the spool valve box and feeds the hoe with fresh hydraulic fluid, and the line that is coming straight back in the picture and attaches to the left side of the spool valve box, is the return line to the filter, then to the reservoir. To help orient yourself to my pictures, this is looking rearward toward the hoe. Also, remember that both lines coming from the spool valve box have quick coupler fittings (the line supplying fluid should be a female and the return line should have a male coupling on the end of it) , and the reason for this is: when you remove the hoe and use only the tractor loader, this allowed the hydraulic system on both hoe and loader to be isolated from contaminates and still operable as well as loosing, and wasting fluid. Remember, these 530CK's were being marketed to more than construction companies; which would leave the loader/hoe as a unit and were being sold to landscapers, yard handler. farmers, etc.


Looking rearward, but the right side is the feed line and of course is clearer than the other side because there is nothing in the way, easier to access too.


OK, in this shot you can see where the feeder line (with quick coupler center)is attached to the loader spool valve box. It is the line that is all metal in the picture. The main line that feeds both loader and hoe is the largest on the right and 1" ID., it comes directly from the hydraulic pump in the front of the engine.


I included this one to show you the large 1" line as it transitions from hard tube to flexible hose (on the right). The line, lower left, (the return hose) going to the filter that has a female fitting on the lower end of it, that when detached would then hook up to where the hose that you see in the center is. This would now allow the hoe to be removed and only the loader would be functional. I know it looks smaller than the hose going up to the valve box, front and center, but it is the same size.


Here is the parts picture that I color coded for my purposes, it helped me visualize all of the connections and hoses, there are so many and it is confusing if you are not doing this for a living. I labeled all of the hard tubes and color coded them to keep them straight. If you right click each one of these pictures as you peruse them, then save them to your computer, you can then blow them up and magnify for clearer viewing.


This is the breakdown of the whole hydraulic system: loader and hoe, again, save this picture to your computer then use whatever picture device you have and study it in a larger format. Hope this helps and if you have any more questions, I'll be glad to help if I can, Stan.

Thanks, Stan! That is fantastic information and just what I needed. I'll post some pictures of the tractor tonight. BTW, there is a valve assembly built by Gresen that I will be disconnecting. I was able to get the engine started today and when I tried the valve, it actuated the arms of the Eagle Hitch (3-point hitch). I removed the arms since it appears that they will get in the way of attaching the backhoe, and I'll be attached the hoe where the Gresen valve assembly was attached.

Thanks again for the time and effort you gave to my answer. I sincerely appreciate it.

I recently purchased a Case 530CK myself, but have no idea of model year. I appreciate all the insight your posts have provided.

Well Dean,
I thought I would include some serial numbers and years for you to compare with your tractor in order to establish the year that your machine was manufactured. Also, here are the places to look on your 530CK for the serial numbers: for the tractor itself look on the right side of the instrument cluster, about half way down riveted to the sheet metal is a tag with serial and model no. or on the right side of the engine block low down. On the left side of the loader support frame by the foot step, is a plate that is identical in size to the tractor badge with the loader model (like: 32) and serial no. On the right side of the backhoe control levers pedestal is a tag with model (like: 32) and serial no.

Glad you have enjoyed the posts and I hope this helps you in identifying your loader/backhoe!

Very Good, Thanks!! It turns out to be a 64. It's a good solid rig and relatively straight for as old and as well used as it is. But it all seems to work reasonably well.

 

[DeanMurphy]

The Starter recently went out. I used to be able to get it turn over with a couple of gentle taps, but that has ceased to work anymore. The original Delco Part Number I found (1107750) is simply listed as obsolete, and i can't seem to find a cross for it.

Has anybody had to replace their 530 Gas Starter?

If so what did you use?

Thanks in Advance

 

[pmsmechanic]

I googled "1107750 case 530 starter " and found quite a few for sale. Good luck!

 

[mayorbob]

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. The steering is a traditional steering shaft down to a worm gear turning the steering arm under the front of the motor. There is a single hydraulic cylinder that has a valve on the end, so when you turn the steering wheel, it pushes on that valve, opening up the hydraulic cylinder, thus helping to turn the way you want. I have finally found a picture with the parts listed...but it's taken me 3 years to find it. When I'm fully recuperated & get back to working on it, I will at least have some idea of what I'm working on. I pulled the steering box apart (wrong...big mistake!!) to try to figure out how it worked...didn't need to. Ah, but experience!! I was working on getting it back together when I had some reactions (out of breath, etc) that prompted me to call my doctor...result, 6 bypasses! At least I didn't have a heart attack first!! Anyway, I found out there were 4 different steering set-ups on that generation of Case tractors, & mine was for farm work, not construction. I'll post some pictures when I get back to working on it. I may have other problems when I get it back running, but they are in the transmission. We'll see... Bob
