Is the leak on the actual tube or on one of the fittings?

Leaks from fitting at block. Around the tube.

Try tightening that hex nut on the a little bit more so it seats the ferrule inside better and see if it works.

I’ve tried that and it won’t budge anymore. I think a new ferrule might work, but can’t find that either.

Can you take all that metal stuff off and just put the hoses in each end like a normal cylinder?

That’s how my hydraulic top link is.

It's most likely metric tubing, the compression fittings on the valve are part of the valve cartridge so not really replaceable, I think there's an adaptor that will convert them to a common size but I haven't looked into it yet.

They make adapters to go from banjo to NPT. You could take everything off the cylinder and attach the hoses directly. You could also take that cylinder to a hydraulic shop, they might have a way to replace just the steel tube that has the leaking fitting.

I was told that was a check valve and I should leave it on? Is that not true? I will check a hydraulic shop also. Thank you!

Slightly new topic: I have new Mahindra 5155 arriving next week to replace my 4550. I use it mostly for three thinning for fire protection and for firewood. Have received a new KRPAN logging winch very similar to the one I had for my 4550 but stronger. The old one is in the photos below to help with my question (it is no longer needed and is available).

Getting to the question: I am considering putting in a hydraulic top link controlled by the rear remotes but am concerned that it will extend by itself when the ~10,000 lb max pull of the logging winch goes mostly on the top link which is just below the chainsaw scabbard. Would appreciate any thoughts on that and what I could do to minimize that.

Thank you.

Top link with a pilot operated check valve will help keep the cylinder from drifting, also isolate any pressure spikes from the control valve.
