L245 Hydraulic cylinder

[abeconnally]

I am trying to diagnose a hydraulic issue on my L245DT. The 3 pt lift won't raise.

So, I have removed the cylinder head, and I notice there's some leaking around the piston. But I can't get the piston out to change the rings.

Do I have to take the entire assembly, seat and all off to do this?

DO you have this manual? It will download - PDF file Look at page 60

I have the manual, but I'm unclear as to how to get the piston out. Do I have to remove the entire assembly? it doesn't really say how to get it out

Did you get the piston out ?
If Im reading correctly it says to "hand push piston and liner out"
So I assume this is the problem, in that it wont come out when you try ?
If you cant "push" the piston out by hand, then Im curious if you need to remove the rockshaft housing, prior to doing so. I know it doesnt say to do that, but thats what it sounds like in the procedures.

No, I didn't, I think I have to take the whole assembly apart.

You can't "push" the piston out, because pushing makes it go back in. You have to pull it, and there's noting to grab on to.

So, I think the whole housing must come off to be able to push it out.

Would pushing down on the short rock shaft arms push the piston outward in the cylinder? But don’t lift them very far by hand, there is a con ting rod that can fall out of the assembly.

Yeah, push down or pull up on the arms. It should come right out. I don't think you have to remove the big cover.
