Jockey wheels, maintenance?

[raleighnut]

Why? i.e. for what purpose? Why do the 11 speed RDs not have float? Or do they?
Observe that the RD-5600 is a rather 'old' 10 speed. Perhaps Shimano realised/decided/determined float had no merit.

My 5800 has far more float on the upper jockey compared to the lower, I just reached behind my desk to check.

I hope that desk of yours has what used to be called a "modesty panel" if you're doing furtive bike fondling behind/under your desk.

My colleagues are used to it, plus the associated beeps from the various charging devices.

Diesel-d at the same time as the chain
A wipe over of the running surfaces, & an old toothbrush to 'force' some into the casing/shell

Threadlock on the screws every time when you put them back on after taking them off for a thorough clean.

Oddly, the lower bolt on my CGR (long-cage 105) keeps tightening up
To the point, that back pedalling, makes the chain 'droop' enough to touch the chain-stay

Well perhaps threadlock would stop it 'tightening up'? Surely you screw the bolt in till it's tight. How can it tighten? What is tightening it: friction from the jockey wheel's rotation?
I reckon it's more likely there's something else going on to have this effect.

Yep, I'd say so too, the jockey wheel should be free to rotate no matter how 'tight' the bolt is clamping the bushes and sideplates.

It's never been dropped on that side *, & it's only started happening in the past 2 - 3 months
Slacken it off by 1/2 turn & it's okay

I've checked the cages with a straight edge (steel ruler) & they're okay
There's no visibe imperfections to the 'covers'/casings
Bushing seems okay too

* One 'down' due to ice a year ago, but that was onto the left side of it
