All the tensioner bolt is doing is holding a bearing in place. The tensioner isn’t like the coil,spring loaded ones I’m used to. It’s a spring and a hydraulic shock.
The electrical equivalent would be like an LC circuit somehow I think…
so the bolt need only be there to allow the bearing to move wi5 the oscillations of the system. Tight enough to not back out is tight enough.
I still have to wonder what/why I had all that grey powder on the threads when I removed the tensioner…. I had cleaned, primed, and loctited the threads. Could it be that I didn’t use enough loctite? I’m actually wondering if use of the primer was the issue.
Loctite 7649 is a copper salt in acetone. Copper salt in solvent in an aluminum casting, with heat… what could go wrong? It says for use in low activity metals, and includes anodized aluminum. Maybe this aluminum didn’t have a thick enough oxide layer and the copper and aluminum reacted, damaging the aluminum?
This FAA technical publication describes the powder I saw in the threads. I’m wondering if the primer was really the culprit…
