Hello,

This is on a magnesium 034S crankcase. The Service Manual lists no fewer than 4 different types of Loctite. None of the numbers look familiar. Any suggestions on what type I should use? I do happen to have some removable 242 Threadlocker available. Don't know if this has to be temperature or bar oil proof or not.

Thanks,
Steve

I think the rear stud goes thru to the oil res for the bar oil, so clean thread first then fit stud.
242, blue, medium strength loctite

243 is oil tolerant medium strength thread locker. Basically the same as 242 as far as strength etc, just more tolerant of oil.

I guess its specified due to the stud going thru to the oil tank on one of the studs.

I was looking at an 026 at the time but it's in your 034/036 manual as well(page 7-8), on the toque specs table(though it mentions 243 vice 242).

Is see it now! "Guide Bar" is different than "Guide Bar Stud" Must be German translation!

BTW, BOTH studs go through to the oil tank.
