Help, no Hydraulics at all

[combanx]

Hi everyone,

Need some help. I was using my MF GC2310 and all of a sudden all my hydaulics stopped working. I looked for the sight glass at the back and it seems full. Also checked to see if there was a leak anywhere and nothing. There is no odd noise or anything out of the ordinary. I was using the backhoe and started using the loader and it all just all stopped working. Any ideas what I can check for, I live at least 2 hours away from a dealer and do not know what to look for.
Thanks for the help,

Combanx

First, welcome to TBN. Second, if you have quarter inching valve for 3-point hitch, make sure it's centered and not stuck in the "up" position. If you have position control... never mind.

Check all quick connects. They may look connected but may not be. It can stop the flow and stop all of the hyds. If the tractor sounds like it is loaded when it is not doing anything you have a blockage in the hyds. some where.

Yup, the #1 problem when this happens is one of the QD's (quick disconnects) for the backhoe is partially disconnected.

I recently fixed my 1428v which had the same problem. It ended up being the o-rings in the loader valve. was tough to figure out. I ended up bypassing the loader valve and after that the 3 pt was working fine. Was easy to rebuild with new o-rings. Good luck

combanx- did you find the problem? Those of us with 2310s would love to hear about it!

Hello Everyone,

I will be working on the tractor on Saturday ( tomorrow )
Will let everyone know what I find,
Just want to say thanks to all for all the suggestions, will try them one by one

Thanks in advance for keeping us all posted, and welcome to TBN!

Question: When you said that you had "no hydraulics," do you mean you also have no motive power? Will the tractor still drive around? (They are all on the same system, same fluid, same pump....) How many hours are on the tractor?

Approximately where are you located? There may be someone nearby to assist--

Hi There,

Well it snowed a **** of alot last night, about a foot. We live in Haliburton Ontario Canada. Ski and cottage country. I will be headed to the garage in about 30 minutes. Yes the tractor still drives around. I was digging a hole with the backhoe just before the hydraulics stopped working. I hope it is not the pump. You said the drive uses the same pump....thank god I was worried it was the pump. I will start taking everthing apart step by step and will let you know. I have about 250hrs on it. When it had it first service I loaded it up on a trailer and when I was driving it off it slipped and broke off the hdro filter. It also snapped part of the pce that the filter screws on. The dealer replaced the filter with one that was a little different. The Massey one was too recessed to catch the thread part. But this is not what is causing this issue. I am just telling everyone that it is a poor design down there and a skid plate would be great to have.
I will post as soon as I find out what the issue is.

Combanx

. I am just telling everyone that it is a poor design down there and a skid plate would be great to have.

That information is 6 years too late for most of us.

Had you been here sooner, most of us would have advised you to do your own service, and your incident would have never happened.

Since you took it to the dealer, you should ask them why they did not suggest, and install the shield that Massey makes to protect the filter, part #79026385?

Apparently you bought one that was produced before the fix, and had not been retrofitted. In either the second or third year of production, the shields were installed on the new machines from the factory.

Kubota also went through a similar problem, the fix they usually use to repair the broken filter mount on the GC's, is actually a Kubota part.

Clearly the fluid is not getting to the hydraulics, I would not rule out an obstruction in the line, from the filter incident.

Sorry, duplicated tx2310's and kennyd's post

Hi Everone
Sorry I posted a new topic, I still new and instead of staying here I ended posting a new topic....
Well I have tried everything, cleaned and removed all Q.C. hoses to the front loader then bypassed the hoe by connecting both hoses together at the back. The tractor is able to drive however all hydraulics are dead...
I also took the filter underneath off and very little hydraulic fluid came out just sort of dripped. Have any of you removed the filter before draining the hydraulics, if so did the oil come gushing out or not. I tried to look at the little glass window but can't really tell looks full.....then I tried to remove the small plastic screw that you take out to fill up hyraulic fluid, and cannot even get that out...what a mechanic I am... It is rounded off, cannot believe this because I bought the tractor new and it has only been to the dealers once, so they must have rounded the thing off, what a spot to put that cap...
Any suggestions would be really appreciated, I will try again tomorrow to remove that cap, otherwise I will bring to the dealers next week.
Thanks again guys you have all been great with ideas...
Best Regards
Paul

You cant tell if the tank is full or not by looking at the sight glass. Cant use a dip stick to test the oil level in the tank.
You say not much oil dripped from the filter. I think that the oil tank is empty, get that plug screw out and check the oil level with a dip stick. No need to tighten that tank screw that tight.

 

[combanx]

Thanks transit, for some reason I have the same feeling, but where would the oil have gone. I have not added oil, but does it just leak out somewhere slowly or what.....like around the cylinders
I will attempt to remove the plug again tomorrow, what a crazy spot to put it.
I can see if you do not have a back-hoe but if you do............just nut's.

Thanks again, This is one of the busiest forums I have ever seen...great group of helpful people....

Best Regards,

Combanx

If you had a leak you would see it. If the tractor will move then it has to have hyd. fluid since every thing runs off 1 pump. I do not have a hyd circuit diagram to see how the steering is routed. But the time I had a problem with a quick connect the power steering was not affected. When they fixed the filter they may have allowed shaving to get into the system and have now caused a blockage some where. Make sure all the connections are hooked up to the correct places.

Mine is a later model ('07), and does have the filter guard. As folks have suggested, you should get the retro-fit, when you get the tractor back on line.

I've seen some 2300 tractors where the plastic fill cap fits well and unscrews by hand, but mine sure isn't one of those!

I have to use a pair of Channel Locks on it every time; either the threads were poorly formed or have been damaged, I suspect, in either the tube or the cap.

I don't worry too much about it, as long as it stays put-- but go ahead and use a tool to get it off. When wandering around dealer lots, I got in the habit of just trying those caps; seems like only one in four or five was actually removable by hand. I know it's a bear to get at with the BH on!

Wish I could help more with your hydraulics, but I'm still learning, too, and have never had that kind of a problem with mine -- unless it was an obvious mis-match of QCs.:laughing: Thanks for keeping us posted.

Hello everyone,

Well I have tried everytning that I could.
Took all quick connects off and cleaned and oiled, put back.
Checked still no hydraulic power.
Drained all hydraulic oil and cleaned screen in behind rear wheel, notice that there was some really small pces missing from it. Anyways took it out and left it out just to check what would happen....still no hydra power.
Changed large oil filter on hydraulic pump....still no power. BTW also when doing all this changed out hydraulic fluid with fresh one.
Since doing all of this now the tractor will not even move back or forward.
Before I could not operate the hydraulics now cannot even move the tractor.
Also forgot to mention that I disconnected the rear backhoe and reconnected the hoses like they are suppose to be when not connected to backhoe, they are connected together.
Any ideas guys.......

This is sounding serious... but give it some time:

After changing my hydraulic fluid, it seemed to take forever for the thing to come back up to pressure; I figured for sure I'd broken something!

But after ten minutes or so of running, stuff finally started to work normally.

Have you given it several minutes of idling and still get no movement?

 

[combanx]

Yes I let it run for about 5-8 minutes

If it is the hydraulic pump, is it rebuildable or do they have to put new unit in.
I heard a new unit is about 3K ????
