For an engine rebuild, conrods, cam gear, case, etc... Halfords sell a stick, loctite 248, which is medium strength, and blue. But I remember it being red?? And there seems to be so much choice! So which it the right one for the rebuild?
Do you need thread lock? I thought correct torque was sufficient. I could be wrong, but the few engines I've stripped haven't shown signs of its use.
Red, green, blue, yellow and clear! We use blue for threads, yellow for bearings and green for anything that should NEVER be undone!
I used the green (monkey snot) on a Norton gearbox once, I had a 4ft breaker bar on and still couldn't shift it!
I tend to use 222 Loctite which is pink on aluminium, its low strength thread lock. Blue 243 on things that are prone to vibration, but I need to be able to undo(medium strength). Green 270 is high strength and difficult to undo. The yellow 641 stuff is bearing fit, not for use on threads.
Back to the loctite question... Should I use loctite on the case nuts? Don't think it's necessary, not mentioned in the manuals, but wondered if it was A new tip? (Soon, I'm sure you will get board with my questions. So I thank you )
Thats a good shout. It seems that even Henkel give out mixed messages as to how dry torque settings are affected. Perhaps best to phone their technical department if it's a concern?
