do not use green loctite (any # green loctite) on any bolt or screw,its basicly designed for sleeve retaining.use red on permenant bolts & blue on stuff that may be taken back apart from time to time (this is especially on the crank bolt,never use green on that & even use red sparingly on it too)
That would be correct. When I replace the motor shaft sleeve on a centrifugal pump for the mainshaft seal. The only thing that keeps it in place would be Loctite 680 Green retaining compound. I as well would not use it on anything except the sprocket shaft seal if the fit is too loose.. Stick to 262 or 272 red...

Kirby,
Are you saying you use blue on the cam bolt? Do you use red on the comp bolts (both the older TC versions and the newer Torx bolt)?
It's retaining compound. You don't ever wanna accidentally use that stuff. Put it in a drawer and forget about it. Then call the guy who sold it to you and have him send you some red 262.
Suggests you just go by colour and not the technical spec written by Henkel.
Another example of green is Loctite 290 that is designed for already assembled threaded parts. Its thin viscosity is designed to wick into the threads.
