Don't let WD-40 get within a half mile of a piano, any piano.
Hello Harry,As you test and re-test the torque on your lubricated pin, exercising it back in forth, you are helping your WD-40 do it's job of reducing friction.

You say it has already "dried" over a week, which omits the main problem --- about a quarter of it is mineral oil, which doesn't "do" drying out. Gumming up, perhaps, that would take a lot longer than a week.
It's a "secret formula", but here is what Wikipedia says is in it:
WD-40's formula is a trade secret, and has not changed over the years, according to historian Iris Engstrand.
To avoid disclosing its composition, the product was not patented in 1953, and the window of opportunity for patenting it has long since closed.
WD-40's main ingredients as supplied in aerosol cans, according to the US Material Safety Data Sheet information, and with the CAS numbers interpreted:
The UK (and EU) formulation is stated according to the REACH regulations:
The Australian formulation is stated  as
In 2009, Wired published an article with the results of gas chromatography and mass spectrometry tests on WD-40, showing that the principal components were C9 to C14 alkanes and mineral oil.
Harry, the important thing is that you will never do it again.
If a pin starts to slip enough that it won't hold pitch, put a few drops of water thin CA glue at the seam where the pin goes into the bushing. CA follows cracks with tremendous enthusiasm. Don't use too much of it, but if the note still can't be tuned ten minutes later, you can add a few more drops.
Don't fiddle around with the torque wrench again. Only deal with a possibly contaminated pin if you need to change the pitch.
