1010 RU Hydraulic pump alternatives

[M_bridges38]

I have a '63 1010 with a bad hydraulic pump. I took the pump off the tractor and you can see the shaft has been worn down pretty bad. My hydraulics were completely unesponsive. My guess is that this shaft wasnt engaging the transmission because of how warn down it is. I want to put a PTO driven pump on the tractor so I can use the bucket. Most of the PTO pumps that are the right GPM that ive seen have a max PSI of 2500 or 2250. The original pump had a Max PSI of 2000. If I tried to use one of these PTO pumps is it just going to be way too much for the system?

More info would help. Does your loader have its own control valve? If so, does it have an adjustable relief valve? If it does that will control the pressure from the pump in an open center system.

Have you checked with one of PartsASAP's salvage yards to see if they have a good used pump?

It looks like the 1010 had 3 possibilities of pumps based on serial numbers and with or without power steering. Check out the hydraulics pages.

The loader does have its own control valve. I dont know if it has a pressure relief valve. I was just going to plumb the pto pump onto the suction and pressure lines that are on the tractor.

I live in Maine and most of the salvage yards ive seen online are in the midwest. I cant justify driving or flying out to one of these salvage yards to look for a replacement pump. Will they take parts off and mail them?

These are reasons im interested in a PTO pump. There are some online that are 2000 psi max but theyre $1000 where the ones that are 2225 psi are like $250.

Post a couple pictures of your valve and we should be able to see if it has an adjustable relief valve.

Most salvage yard pull, check and ship parts. I am sure PartsASAP does.

 

[M_bridges38]

Oo thank you I didnt know they shipped.

I circled what should be a relief valve in one of your pictures. A picture taken from the lever side of the valve showing the levers and the whole head of what I circled should clarify it.

Did the direct message (the envelope beside your handle at the top of the page) I sent you go through?

Awesome, thank you. Im learning this system kind of on the fly. I have the owners manual and the Service manual. Your message did go though. I appreciate the insights. Ill reach out to those places and see what I can find.

There is a pump for a manual steer tractor on ebay for $150. I wonder if I would be able to either 1.) Use it as is and just nit having power steering. Or 2.) Take the pump apart and replace that shaft and gear on my pump with the one from the ebay pump.

I expect the internal parts might be different.

You can use the online parts catalogs at jdparts.com. I have linked the 1010 utility tractor below. It is likely better than the one I linked before for your RU model.

Your loader will have a parts catalog of its own. The loaders were not included in the tractor parts catalogs at that time. Have you found any marking to ID the loader model? If you don't know the model post some pictures of it and someone might recognize it.

looks like its a Model 36. I didnt even know this badge was there until just now.

Here is a link to the Model 36 Farm loader parts book. That plug is the relief valve port. It appears non-adjustable.

You might want to double check the hydraulic pressure on that 1010.
It is no where's near 2000PSI. It should 1100PSI, review your 1010 manual.
2000PSI may damage the rock shaft housing, steering, etc.

I had a new shaft made years ago for my 1010 w/ power steering.
He has since retired and sold his business.
My shaft did not look near as bad as yours, the pump was still operational.
I will take a look and see if I can find it.

Oo good catch. Thank you. Im open to all the help I can get.

Is #23 not a slotted screw? Would turning that screw adjust the pressure?

One thing i'm a little confused about is that the service manual for the tractor says that the relief valves will open at 1080 psi. The manual for the loader says that the relief valve should read 1300 to 1600 psi. I assume that the relief valves in the tractor supersede the valve in the controller for the loader?

 

[Jim.ME]

It appears it is and I didn't study your pictures that show the head of that plug. Looking at it for that detail now, it appears yours is slotted.

Does your manual have flow diagrams? It is possible the tractor relief valve is for the remotes and is set lower than the loader valve if the oil to the loader bypasses the remote circuit. I will have to see what I can find for a 1010 manual that might have that info.

hopefully someone more familiar with the 1010 hydraulics will be along to offer advice.

The relief valve on the 1010 governs the complete hydraulic system (steering, rockshaft, remotes). If the wrong relief valve is used on the loader (which it is), and depending where the loader is plumbed into the1010 (before or after the 1010 relief valve) will determine which valve will be able to perform its function. If the loader is plumbed in before the 1010 relief valve, then the loader valve will be the last lines of defense. Since the input shaft is severely worn, I suspect that the loader valve is putting undue stress on the hydraulic system causing the wear as shown.

Years ago, I removed a loader on a 1010 that i bought. I capped the lines off to the valve and the system over pressured and broke a gear in the pump. It took a couple of years to find a used pump (power steering) and then it took a couple more years to find another donner pump in which I was able to build one pump out of two units which is on my shelf as a spare.

 

[Jim.ME]

I do not believe you will be happy if you delete power steering and plan mainly on using the loader.

I suggest checking salvage yards for a good used pump that fits your tractor. Identify the one you need using the parts catalog, as it appears there were two different pumps used with power steering, as shown by the serial number breaks.

Given the looks of the pump shaft what is the condition of the coupling it fits into?

Adding a PTO pump will restrict using the PTO for other things. No doubt a PTO pump can be made to work with the right plumbing and possibly having to add a relief valve to limit system pressure and priority valve to supply the power steering.

Thank you for your insight. The reason I keep coming back to the PTO pump is because they're readily available and relatively cheap. If I could find an OEM pump, I would obviously prefer that. That being said, as you alluded to, I assume the coupling that the pump fits into is also warn so even if I did find a working pump, it might still not work. I know these are not very desirable tractors and I'm probably wasting my time but it's a challenge now and It was my Dad's. As of right now, the pump is off. I could just run the tractor like this for pulling a trailer or as an anchor for a winch. I'm just imagining what I could do with a loader.

 

[Jim.ME]

You should be able to look and see how bad the coupling is.

It feels pretty worn. I just don't know if it's "too worn"

Hypothetically, what's the worst thing that would happen if I bought a manual steer pump for a 1010 and put it on? They run at a lower pressure than the ones with power steering. So it will be way harder to turn and the loader might be slow. There is one on EBAY right now for $150 and I see them for sale relative regularly. I'm so tempted. I just don't want to mess up the transmission.

 

[Jim.ME]

I don't believe there is that much difference in the pumps, beyond losing the power steering.

There are some used drives available on eBay as well.

I suggest you figure out which of the two different power steering capable pumps you have and check with PartsASAP (and other salvage yards) to see if you can get the right pump before just grabbing a pump. A good yard may be able to tell you if either one can work as a substitute for the other.
