I’m definitely loading the spring the right way but before I get all the way round the hooked end of the spring forces itself out and jams in between the cages.
This doesn't compute - loading the spring is winding it up, not unwinding it. If you were winding it up and the end let go, it would have gone inside. It could only be poking out if you were trying to unwind it, right?
Kimmo-
I recall having the exact same problem once with a SLX derailleur. No I wasn't unwinding it, first thing one checks after the spring pops out. Sadly can't remember what I was doing wrong or how I solved it.

In hindsight I’m not sure what I was doing. I was getting annoyed and maybe I was rotating it the wrong way. And I was possibly over torquing the p-axle/cage bolt. Anyway I’ve replaced the spring and the mashed up seal and it’s all together and I’ve wound it round and it’s all good.
However a few movements back and forth of the cage and it goes all tight again. So I back off the bolt and it’s nice and springy again. But again a few movements back and forth of the cage and it goes all tight. Moving the cage back and forth is tightening the p axle bolt. No idea why. I’ve taken it all apart, made sure it’s greased, backed off the clutch tension but the same thing keeps happening.
I should add that the mech is totally unused, so it’s not worn or full of dirt.

I’m getting increasingly irate here. I’m changing the cage on my GRX mech to the cage from an M8000 mech, basically changing from medium cage to long cage so I can run a wide double drivetrain.
Anyway, every time I try to spin/load the cage, the hook on the spring pops up. It happened last week, I thought oh no maybe I went the wrong way accidentally without thinking. So I ordered a new one and a new gasket/seal because it completely chewed up the seal last time. Go to install it this weekend and the exact same thing it happening. I’m definitely loading the spring the right way but before I get all the way round the hooked end of the spring forces itself out and jams in between the cages. I’ve tried bending the hook in slightly so it grips better but the same thing just keeps happening. The seal is completely chewed up again. Also a photo of the spring showing it slightly bent up which has now happened to both.
What am I doing wrong?
