2160f Hydraulic Help

[Millsi]

G'day guys, having some hydraulic issues with my tractor.

It's an early 2160f non hst, so the model that shares oil between the hydraulics and gears.

The hydraulics have never worked since i got it a couple of months back.

Have only just had the chance to have a look at it.

The dip stick isnt even registering so the oil is low which is a pretty big give away.

However i would also like to clean the relief valve and filter but dont know where they are located if someone could post a pic or a detailed description that would be great. Also need to know where the drain plug is and how much oil it holds approximately.

I'm also not sure what oil i should be using? The manual suggests a bolens product which i have zero chance of finding here in Australia.

Once i have done all of the above if it still doesnt work then i will look at the hydraulic line from the pump and the pump itself.

Thanks

James

Can't do much damage with UTTO for shared sumps.

Sorry, can't help with component locations.

cheers

It took a fair bit of 80w gear oil till it was full but made no difference.

So i undid the banjo bolt circled in red and started the tractor, seems the pump is working as there was plenty of fluid coming out

When i pulled the top off the hyd cylinder there was very little fluid in the cylinder itself.
It seems that the fluid is geting blocked before entering the cylinder via the port circledin green above.

Next thing i pulled what i can only assume is the relief valve apart. in the picture below is how it was assembled, though to me it seems like the part circled in red was installed the wrong way around. Can anyone confirm?

Put it in the opposite way but made no difference, probably wont until i get some fluid flow into the cylinder.

On the whole the fluid seems pretty dirty.

What do i do next?

cheers

Hi James - pretty obvious but have you checked the lift arms are actually free to move by hand (I'm sure you have)?

Is there no pressure at all on the lift arm - ie if you hold with you hand is there anything there, even just the indication of vibration to give an indication that anything is getting to the piston. If so it might be that your pump is working but not developing enough pressure. Which equals new pump or at least dismantle and even the entire return and pressure loop inc the pump - then flush through with clean oil.

The other area to look at is that distribution block above the banjo bolt - it doesn't look like its capable of ditching pressure back to the return line by its position, but then thats what it should do. Could be that it is diverting pressure back to the sump. may as well take it off and see what is going on. Clean out the lift control block at the same time.

Have a look at these parts diagrams to get a better idea of what you are looking at: ftp://ftp.rapid.ch/Iseki/Traktoren ...tzteilliste Liste de pieces Spare parts list/

Pull all the filters and banjos at least and clean them out.

Good Luck!

Dantz, yep lift arm moves freely.

Havent held my hand on the arms, but they dont move at all.

I pulled the 4 way valve apart and everything looked good except part of the prv was pitted and may have been bypassing fluid.

I assume the distribution block that alloy thing just above the inlet banjo fitting? to me that doesnt look like it was a standard fitment to the tractor but i for a loader that may have been fitted in the past. I didnt pull that off as yet.

Ended up taking the whole assembly to the hydraulic shop to test and then fix if necessary. At least then if it doesnt work then it's probably the pump.

Yep that alloy thing looks like a dist block for a front loader - worth a look if all else fails. Just thought though, that dist block gives you an excellent way to check the system pressure - can you get hold of a pressure gauge and connect it to the dist block? If you get a system pressure then you know the problem is either the valve block or downstream.

Could easily be the PRV passing, but can't you screw it right down - effectively locking it to check that? I just got a TX1300 with a front loader powered through the PRV (bad design, will change!) and I can tell you that with the isolating valve open the rear lift arms just swing free.

You might have to hook the hoses that was for the loader together so the oil can loop the oil.

The shop replaced the rings around the hyd ram, shop tested it and it worked ok.
Got it home and no joy.
Have taken the pump to them to see if they can repair it. If not then new pump will be $450 for a genuine. Can get aftermarket from the us for $370 but they want $170 for shipping. so will prob just go for the local option.

I think you might be on to something. Hydraulic shop has told me the arms work and have just rebuilt the pump though I still can't get the 3pl to function.
I took the distribution block off tonight and there is flow but it can't go anywhere due yo being capped.
Does the distribution block I have come standard on my tractor?
