Answered Jockey wheel replacement and thread lock?

[Beekeeper]

Planning on replacing worn jockey wheels on Shimano XT 11 speed.
Is thread lock actually necessary or recommended and if so how much do you apply?

I usually put a tiny drop of blue thread lock on after having one come apart on a ride.

That’s helpful. Thank you

It works better if the thread is clean.

On my Sram X01 mech the guide pulley ( top) is secured with red loctite ( as standard out of the box).............bottom pulley blue loctite.

Just use blue or nut lock.
I only say blue after 30 odd years in the motor trade blue was for securing things that could be easily undone with basic hand tools. Red was for studs that didn't often need undoing. And basically if blue didn't work use red stud lock and if that was no good, weld the fucker together
