The loctite sounds like a good idea.  Working on vintage race bikes we
take things apart a lot.  The steel screws tend to eat the aluminum
threads and they rip out.  I started using Never-Seize on a lot of
things.  As time went by I noticed there was more clearence between
the threads.  That was when I remembered the bit about the clamping
force.  Problem is, if you don't tighten things as much, and the
threads are less prone to sticking, things could loosen up and come
apart.  With loctite you don't have to put things together so tight to
be sure they stay together.

 


Good point - especially when it comes to bikes having been taken apart
a lot.  I've also seen the results of over-tightening bolts (on
others' bikes) where what you describe happens.  A little blue loctite
gives you the confidence to not over-do it, knowing it will help keep
things from rattling loose.  I use it on practically every bolt on my
bikes.

I have never heard of white locktite.

 


Really?  I use that stuff every time I put a drain plug (primary,
tranny or engine) back in the bike.  HD techs do as well.

I checked my Website and found a picture with the white loctite tube
sitting on the bench.  It's right beside the red toolbox and just
below the paper towel roll here: http://www.xidos.ca/Portals/0/Front%20Whee=

You can buy it in smaller tubes, but a large tube like that has lasted
me for 10 years now (and is finally getting near empty).

You should be able to find it somewhere; although it doesn't seem as
commonly sold as the blue and red loctite.  It's more of a thread
sealer, I think.  It probably helps a little, holding the bolt from
loosening too, but probably less than the blue.

There is no one single White Loctite® product, rather, a range of similar
products, depending on the application.  567 or 5770 look appropriate for
use on a sump plug.  Personally, I can't see why you would ever need it
on a sump plug, if you are using a crush washer and torque the plug to the
correct torque, there is no way the plug will come out and no way for the
washer to leak.  Using a crush washer, the threads have nothing to do with
providing a sealing function.
