    Default Hydraulic cylinder disassembly

    One of the power steering cylinders on my MF35 Utility is leaking badly. It's an aftermarket cylinder. I ordered a rebuild kit but can't figure out how to take it apart. There was a snap ring on the rod end of the cylinder which I removed but still, nothing comes apart.

    Pics are below. I believe it's a Tisco cylinder. I called them and they have no schematics available.

    How can I get inside the cylinder?

    I think the end of the cylinder where the rod comes out is threaded on. Can you tell if it is? Try a pipe wrench on it and see if you can remove it.

    I put a pipe wrench on the cap. It takes quite a bit of force to turn it. I've made 3-4 complete turns and it hasn't come out at all. Looks like it's just spinning there.

    any locating pins or set screws around the circumference. might be a press in style.. I've seen fine thread.. but at 3-4 turns.. youd notice the gap opening..

    If there was an internal snap ring, you prob have to use the rod/piston
    assembly as a slide-hammer.
