John Deere backhoe510-C

[Sambanks007]

I am looking for a John Deere mid pump for a John Deere backhoe 510-C.

Welcome to the forums.

The 510C was a model, however it appears the 510 used a C after the 510 to designate the engine and transmission option. what is the six-digit serial number? I bring this up as the way JD did some suffixes have lead people down the wrong path before.

Mid pump? Are you asking about the reverser oil pump? Have you talked with your local JD construction equipment dealer parts department

Going on you saying 510 C as in the model, here is a link to the online parts book for the 410C, 510C and 610C. Best to use the parts catalog to find the pump you need and identify it by the catalog name and part number. Then you can search online using the part number.

JD 510C parts catalog PC2065

Depending on which pump you are looking for and its current condition, it might be rebuildable. Do you have the technical manuals for your 510C? It is a two volume set, TM1468 (test and operation) and TM1469 (Repairs). You need both, test procedures, specs, and operating parameters are in TM1468 and the actual repairs are in TM1469.

Here is the serial number
I have been to 2 different John Deere and they both said that it is discontinued it is a piston pump not a gear pump.
I would like to find a rebuild kit or a reman pump.
If you know anybody that can rebuild it or has a reman pump let me know.
Let me know.
Thank you very much

According to the introduction in the JD parts book for the 510, your serial number tag is for a 510. Up to serial number 193045 the C means diesel engine. As I mentioned there can be confusion caused by the suffix letter, 510C is a later model.

Here is a link to the parts book for the 510.

PC1240 JD 510 parts catalog

A piston mid pump is nothing I have heard of. To my knowledge the piston pump is the main hydraulic pump mounted in front of the engine, driven from the crankshaft. Look at the hydraulic section and see if you can identify the pump you have. Post the part number. Using the part numbers, it appears some pumps and pump kits are available, but we need to know which one your tractor has to help you. Post pictures of it if needed.

This is the pump we are looking for.

Pouring rain here this morning so I researched the parts catalog and found the mid-mount pump and drive. PC1240 Section 90. I admit not seeing one before.

Did your dealer give you the part number(s) they checked on? Have you looked at the parts catalog? It looks to me like the pump number is AR47533. It has notes "(sub AR102653) (also order R27474 and R26906) (sub for R47532)"

Web searching with the pump part numbers turn up some results, you can chase to see if they actually have one. Did either dealer do a system search for the pump to see if by chance there was one setting on a shelf at another dealer? With the part number you can also call and check with salvage yards, like PartsASAP.

I expect most hydraulic shops that rebuild pumps can rebuild it. I didn't chase the individual component part numbers to see if they were used in other pumps, but I am going to guess most of the parts in it are used in other pumps. They may be able to get a replacement as well. I have sent other JD pumps to a rebuilder here for evaluation and they came back with estimates for repair and replacement.

What is your general location? Seeing that, someone reading this might know of a place in your area to check. And I am going to say it will be best to say you are looking for a JD 510 mid-mounted pump, don't refer to it as a 510-C to avoid confusion with the later model machine, which does not appear to use that mid-mount pump.

May I ask what was reasoning for removing front hyd pump? If anything other than a hyd leak what type hyd diagnostic procedures were performed prior to pump removal?

If another front hyd pump is needed Kin-Tec has good reputation. https://kin-tecindustries.com/products/ar101288/

Another hyd pump source is https://www.abilenemachine.com/hydraulic-pump

Good morning Jim,

I went down that front pump path as well. I searched the R48807 casting number in one of his pictures and it took me to RE13599 housing for the mid-mount pump. It turns out the 510 has a mid-mounted pump similar to the front mounted one. That pump part number only comes up for the 500B and the straight 510. I didn't research all the pump components by part number to see where they were used, however my thoughts are the pump components are likely the same as some of the other pumps, but it uses a different stroke control housing and arrangement.

Jim

My knowledge of JD industrial tractors is very limited due to formally being employed for 21 yrs by a AG only JD dealership. What you state concerning hyd pumps being similar except for stroke control valve housing & orientation is probably correct. Could you please post a photo of the mounting area of your "mid-mounted hyd pump"?

Is original hyd pump not operating correctly or just leaking??

 

[Jim.ME]

I don't have one to post, I am only going by what I find in the parts catalog. It would be good if Sambanks007 would post pictures of the mount and drive arrangement.

 

[Tx Jim]

Sorry for my confusion. I meant to state for Sambanks007 to please post photos of mid mounted hyd pump location.

 

[Sambanks007]

this is where the mid Pump is located at it under the tractor

 

[Tx Jim]

Thank you for posting your photos. Does your 510C also have a front hyd pump?

 

[Fixingfarmer]

It should have a main one just like an ag tractor up front off the crankshaft my 500b has that mid pump controlled by the operator what would be the pto lever on an ag tractor

We call it the booster pump it will run the hydraulics slowly without it I often don’t engage it when just doing something small or moving place to place. I’ve never seen one on an ag tractor

 

[Sambanks007]

Thank you for posting your photos. Does your 510C also have a front hyd pump?

Yes

You’re welcome and yes it does

 

[Sambanks007]

I replaced all the pumps still not getting any pressure or hydraulic fluid to the pumps my hydraulic PTO linkage look like the nut is slipping on the linkage If it does not get full rotation, would it Make it so the pump not to come on? I have in Mark the diagram where I think my issues Any help is greatly appreciated. Thank you in advance.

 

[Fixingfarmer]

do you have steering? And some hydraulic function. Or absolutely nothing? Have you changed both hydraulic filters and the screen below?

I have clean the sump screen, three new filters, two new pumps, fresh hydraulic fluid flush the system, freshened it up again check the lines i’m getting pressure from the transmission pump out of the side of the transmission I checked the PTO pressure port I’m getting pressure and fluid out of there it just is not going up to the front pump it’s a steel line coming off of there going to the front pump

 

[Sambanks007]

I have no steering no brakes no backhoe function no highly function. I have pressure and fluid at the test courts nothing going to the front. I was thinking to check valves down below that port this clog broken damaged. Could I be wrong?
