I thought you might appreciate this ;-)

I don't profess to be in the know with respect to this technology and
probably my attitude belongs to another era but I will not succum to
this type of fix. As far as I'm concerned seeing is believing like the
sight gauge item there's no way better of knowing the tank is full than
seeing fuel in the filler neck. I respect what you say BUT unless there
is no clearance between the pins and holes you can not say the pins are
taking the loads. IOW for there to be differential slop present the pins
don't take the load until they hit the other side of the hole so in the
meantime your loctite is taking the load.
I repeat that my experiences with the nose leg spindle and loctite
"cooks it's goose" for me. I'm prepared to be a prat once but there is
no way you catch me twice thanks.
Regards
Bob Harrison.

Bob,
If I may make the case for the defence .........
Once upon a time in a life far, far away ......I worked for a company
developing and manufacturing anaerobic adhesives. (No ...it wasn't
Loctite)
Part of my job entailed setting up an running the lab tests to quantify
the
shear and peel strengths of the various formulations under differing
assembly (best case, worst case and typical) cleanliness conditions.
Even though I knew how the adhesive worked, it never ceased to amaze me
how
strong this stuff was.
Some test pieces (typically a "ring and pin" for shear testing) would
fail
before the adhesive.
One can use many adjectives to describe these adhesives, but "Mickey
Mouse"
would be THE most inappropriate.
I CAN imagine the PFA sanctioning their use. Anaerobic adhesives
(Loctite is
just one) are a near-perfect engineering solution to our very real
engineering problem.
They tick all the boxes.
They are low cost, simple to administer, lightweight, strong, chemically
resistant and (with the use of suitably masked heat) easy to
dis-assemble.
Most importantly for us, there is no requirement for the entire surface
area
of the two mating components be completely covered or even completely
de-greased. The surface area of the TP4 is so great, that an anaerobic
will
work even if the adhesive does not wick over the entire surface.
Remember that this is being used in addition to (not in place of) the
standard drive pins. The adhesive's only function is to prevent relative
movement - the pins still take the load.
Regards
Nigel (the other one) Graham

Steve,
IMHO I can not imaging how anyone could force you to use such a mickey
mouse fix as glue? And what's more I can not imagine the PFA giving its
blessing ? At what loading does it separate? What repeatability of
performance can be shown ? How can degreasing be guaranteed? Unless it
is used for destructive testing! Better use Jubilee clips ...at least
that is a known quantity factor! The PFA wouldn't clear that either !
Regards
Bob Harrison.
PS Sorry but I can not contain my opinion any longer!

Hi, Do you Know if we will be forced to Loctite the torquetube together?
I for one do not want to willingly use loctite, i would prefer to use
Bobs clamps as
removal would be far easier.
