Rebuilding unloader?

[814jeffw 71]

Has anyone ever rebuilt an unloader. I have been using Suttner ST261 unloaders and was wondering if anyone ever does rebuilds. It's just been easier to replace them. But I have a few laying around and was wondering if they're able to be refurbished. Cold here in Central Pa so just looking to get my fingers on something I guess.Not sure what makes them go bad, seals, wear on metal parts or what. Not trying to skimp, but I'll save anytime I can.

I have been told it is best to replace them. I have a handful of K-7's laying around should I ever want to repair one.

I'd say you're probably right. Maybe I'll take one apart and look for anything visibly wrong.

I did take one apart but did not see anything . Might help if I knew what I was looking for.
