At 70 degrees F you have one hour before Loctite 620 begins to develop its
strength. At 95 degrees F you have 15 minutes.

It is important to remember that Locktite 620 is serious stuff and if you
apply it to all the cap screws at the start of the process you need to move
quickly or else you end up torqueing the last few studs up against the
locktite rather than tightening the fitting down. Not a good result!

Pete, I dont mean to put too fine a point on it, but one part of the
procedure varies from what I have been taught as a plumber!
Putting thread dope of any kind is supposed to go on the male threads not
the female. I think the idea is to insure a complete coverage on the threads,
which you cannot do on the female part.
So putting a few drops in the crankshaft bolt hole is a different technique
from what the Baltimore Gas and Electric company requires of gas fitters!!
I think I am looking for assurance that the "few drops" technique has some
greater virtue.
It just makes more sense to me to coat each bolt threads just before
installing rather than the "few drops".
Is there something I dont know?

Doug,
I agree with you and we put the Loctite on the bolt. However, in Australia
where everything is upside down and backwards (and the toilets swirl the
wrong way) it is the accepted procedure. Probably if you went to work for
Bundaberg Gas & Electric you would have to re learn your technique!
Pete

I have heard that the toilets swirl the wrong way.
However, as long as the brown trout swim downstream, all is well.
I think we will also put Locktite on the bolt threads. Or recommend that our
builders do.

This link did not work for me. I found the TDS at http://tds.loctite.com/tds5/docs/620EN.pdf
It says basically the same thing. However it also says that these times are drastically
reduced by 7471 primer which I believe used to be mentioned in earlier
versions of the Jabiru documentation. The current one (earlier in this thread)
just mentions generic Loctite thread cleaner so be careful what you use.
My limited experience of 620 on Jabiru prop flange and cylinder through bolts,
with and without 7471, is that it does not give anything like an hour working
time at 10 - 15 C. Personally I aim to get things torqued up in five to ten
minutes of applying 620. You just need to do things smartly but carefully, without
rushing as, above all, it needs to be done right.
Also remember that I am no more expert than anyone else and probably less than
many here. These are my observations but everyone needs to decide their own methods
for themselves.
My baby arrives Monday. Whoooo Hoooo
Cheers, Selwyn
