That would not have fixed the PTO in my Corsair II. It was slipping,
more at the low end of the band because the balls had worn a deep groove
in the outer race of the vernier. That required new parts.
And that's the other failure, failing to tune when the spring tension is
highest. Lubrication won't cure that wear.
Yes, Jerry, there are some legitimate rebuild situations such as yours,
but my comment above was "mostly," referring to probably 90% or more
of TT PTO's. In any case, I would try the "clean and relube" process
first... and if that doesn't handle it, rebuild.
Thanks for the input.
