GC2310 Hydraulic System Problem

[DaveCQE]

I purchaced a used MF GC2310 with about 400 hours on it. This past weekend I was using the loader bucket to remove some sod on my lawn when the hydraulic system stopped working. This affected the PTO, three point lift, and loader, the only thing still working is the hydrostatic transmission. The steering also seemed not to work well but that may have been caused by needing to drag the bucket while backing off the yard. I checked to make sure a good connection was made for the two hoses that connect to the backhoe and that it had hydraulic fluid, and looked to see if I had any hydraulic leaks, which I dont see any. Are there two hydraulic pumps, one for the drive and one for the accessories, or only one pump? Any thoughts why things arent working? Any advice would be greatly appreciated!

I believe there is only one pump.

Hopefully it is a simple fix like a check valve.

The backhoe still works?

 

[DaveCQE]

I hope it is not a expensive fix, I cant afford much right now. I am not positive if the backhoe works, I expect it not to work, but with the rest of the hydraulics out I expect it wouldnt work, and right now it is not connected to the tractor. Thanks for your help!

Be sure and check all QC connections. I had one once that looked good but didn't quite make and it gave me some of the same problems. Since it has only 1 pump it is a bad connection or blockage some where.

That sounds cheaper than a new pump, any ideas on the most likely places for this to occur? Thanks!

When you bought your tractor did you by any chance do a service on it.Hows the hydralic filter and the pick up tube screen.If you haven't changed or serviced these parts maybe its time???.If you still have tractor movement how good is it,full power or sluggish?? Power steering does it feel normal?? Like mentioned above maybe try and remove all your hose's quick connectors and re connect them,could be one isn't quite locked down like its supposed to be.Let us know what you find.Were here to try and help and like everyone else the cheapest fixes are the best kind,Larry

Maybe it's time to service them. But, 400 hrs. is not going be a long enough period, for them to be in such bad condition that the system would fail.

 

[ray66v]

Okay, you said you do not have the backhoe on.

When did you take the backhoe off?
Do you have 2 hoses for the backhoe, or 3?
What did you do with the hoses on the tractor, when you removed the backhoe?

 

[DaveCQE]

I did a service on it at 440 hours where I drained out the hydraulic reservior, replaced the canister filter and removed, cleaned and replaced the tube screen and put new fluid which I bought from a MF Dealer, the tractor has about 500 hrs on it currently. The Tractor movement feels normal, the steering was hard to tell since dragging the bucket, but I thought it was slugish. I had removed my backhoe about 30-45 min before the problem began, it is a two hose system, and I have confirmed proper connection together between the two lines that would feed the backhoe. After removing the backhoe I put a backblade on and ran the machine for about 20 min. As I was using the bucket to scrape/remove sod I heard a sound which I had thought was the sound of a hydraulic line bursting, I immediately shut the machine down expecting to see fluid all over, but I could not find any signs of a line bursting or puddles of hydraulic fluid. Thanks for your help and words of wisdom!

When you removed the backhoe, did you re-connect the return line?

On mine, I need to connect the blue & yellow to each other any time the backhoe is off...

I know you said it was a two hose system, but...

 

[DaveCQE]

Yes I did connect the return lines. My machine is a 2004, and I am not sure if these are the original hoses so both are black.

 

[DaveCQE]

I guess I will have to bite the bullet and send it out to a tractor repair place. I will let you know how it turns out.

 

[Rob2310]

I would suspect it is the valve that runs your 3pt hitch. Mine went out on my 2610, while it was under warranty. When this happen, I had the same problems you have. This valve controls the fluid passing out of the hyrdostat unit to the rest of the hydraulics on your tractor. It's not hard to change if you are handy with tools. the most involved prt is removing the sheet metal under and around the seat. Good Luck.

 

[DaveCQE]

That was my thought as well, but wasnt sure. will the system need to be purged for air or does the system automatically bleed the air out of the system? I will contact the dealer to find out the cost of the valve, thanks for your help!

 

[ray66v]

Hydraulic systems with return hoses are self bleeding.

 

[DaveCQE]

Great thanks for the advice!

Hello,

I just read the problem you have and my tractor did exactley the same thing way back in November 2010. I was away for almost 4 months and have not posted a reply to my old post way back. Well here it is....I just brought it to the dealer 2 weks ago and just got it back. My tractor is a 2005 model with about 250hrs on it. The problem is there is a shaft that goes from the hydraulic pump that has splines in it. It goes to another part and slips in. The problem is the shaft does not go far enough in so what happens is the splines wear off and presto all hydrolics stop working. My tractor did drive slow for a bit but then stopped working too. It cost me about 2000.00 to get it fixed. The newer tractors all have longer shafts. The dealer tried to get Masey to pay part of it because it is a problem they are aware of...they paid nothing I was really upset and will be calling them next week. I will get my bill and see if there are part numbers that I can post. This will give you a better idea of what I am talking about. Sorry I am not very knowledgable about the hydralic system.

I know of one other case of this happening, but it is NOT happening to all of them. Here is the 2008 thread involved in the same issue. http://www.tractorbynet.com/forums/...icing/126031-gc2310-wrong-pump-installed.html

DaveCQE's tractor still moves, so I am not certain if it is related.

 

[DaveCQE]

Unfortunately this is exactly what I found out was the problem, I wish I had known before having a repair place tell me, I might have purchased the parts and tryed to fix it myself to save on labor. $2000 is a tough pill to swallow. Let me know if going to masey helps with the cost, though I bought this tractor used from a personal sale so I am not sure if that would matter. Thanks for posting!

 

[ray66v]

Dave, can you see if the mechanic would suggest how much a preemptive replacement would be easier/cheaper?

If more of these start failing, it would be something to consider.
