I have an old 530 Case backhoe that needs some attention. The hydraulic pump that drives the backhoe and loader cylinders is mounted on the front of the machine. It is connected to the tractor by a 1 inch shaft that has 6 spline ends on each end, as well as on the pump shaft itself. The coupler between the pump and shaft is worn really bad and I can't seem to find a replacement. It's a Lovejoy type coupler that fits the splined shaft and I can't find one anywhere. Any ideas where I might find one. The case dealership couldn't even find the backhoe on their computer so they're no help.

Can you post a picture? Most bearing / driveline shops can probably help. Does this site help? Hub City Inc - Non PTO Products

Looks like a regular Lovejoy (with the rubber missing) to me. Try a bearing supplier...

I think I may have found something..!! I'll let you double check, and you can go from there. Here is a link to a site that has all kinds of info for your 530. Specs of all kinds, and manuals you can download for free.
Case 530CK - Tractor Specs
When the page opens, click on manuals in the left column menu. When the next page opens, scroll to the bottom where the parts manuals are located. If memory serves me correctly, go to the section that contains page 67. Scroll down a few pages, or look in the listing what page the pump is on... It shows your pump and drive, and has part number. Shaft number is D30569, Coupling shows A35558. I Googled that number and came up that it interchanges to Case D140524. Coupler appears to be around $54.00.
I Googled the shaft number as Case D30569 shaft. One hit showed that the shaft interchanges with Case part # D64311, which fits a Case 580CK, series B. I went to Case Construction, and looked up the 580CK series B.
I Googled the shaft number, and came up with a new aftermarket shaft for $43.00.
Also saw one site that lists them where I bought parts for my 480C, and they have great prices. Remanufactured Transmissions, Torque Converters, Engines - Joseph Industries
You can always type these part numbers into Messicks, and check the price, then compare shop online, or call Joseph Ind, and compare.
If you call Joseph Industries, more than likely you will speak with Bill Pingley. Heck of a nice guy..!! Tell him Dave from Carroll, Ohio told you about him, and Joseph Ind. He'll know who you are talking about. Of course he may charge you double too..!! Don't think thye are open on Saturday though.
If your Case dealer has these parts in stock, should be pretty easy to compare...
Hope this helps..!!

If space permits, grind the ears off of the 2 pieces and get a compact U-joint welded to the 2 splined adapters.
Another (KISS) method is to use, say, 3" length of correct ID hydraulic hose and firmly clamp to the two shaft ends. The hydraulic hose will flex sufficiently to act like a U-joint and handle those slight alignment variations.

You'll have to look in the parts catalog under the 32 loader & 32 backhoe on the right. Then look at section with pages 61-80. Then page 6, or just scroll down like 6 pages, or 3 clicks using the Adobe page turner... Pump and drive on left side of page.

I have a 530 also, and my pump coupler was also toast.
I just went to tractor supply and they had the rubber part that goes between the two metal parts. My metal parts were worn, but no way they would come off, I think it should be OK with the new rubber.
Surplus Center sells these couplers, they may not be exactly right,
you might need to rig one to fit..
