Hi Jeff,

Only some small suggestions from my end. If you've never used loctite
on your bolt so far, I'd try progressing to the tougher stuff, starting
at a light loctite and progressing to the strong stuff just to avoid
unnecesary bullshit when removing the bolt for t-bolt changes.

I can imagine the difficulty with a strong loctite when you're trying
to
get the pulley bolt off. Then again, if you have access to an 1100lb
impact, who cares?

Might you try marking the pulley and bolt with a dark sharpie marker
to mark their alignment, this way you can see if the slip is gradual?
This
might not tell you a whole lot, basically whether or not the loctite is
sticking or not. If not, you could try tightenting it every time it
slips and see if it eventually ever holds.

I have a factory manual for a 2004 civic and it shows "splines" in the
pulley but no corresponding splines in the crank. Not sure how that
holds up the the Accord or actuality in the Civic (since I've never
removed the pulley on the Civic, can't specualte whether this is true
or not).

Anyway, it sounds like quite a pickle. Good luck!
