Although the real cure has been mentioned numerous times over the 
last 15 years or so,
this question periodically comes up.  The need is mostly to "re-lube" 
not rebuild,
because the original grease has hardened and caused the vernier to slip.
Needless labor is done when not necessary.

1.  Set TT PTO rig (all models) on it's back with front panel up.
2.  Using small allen wrench remove main tuning knob.
3.  Remove felts to expose the shaft entry point into PTO.
4.  Drip denatured alcohol into this entry point and turn outer and inner
     shafts until they free up.  Turn from end to end of range many times.
5.  After a few minutes apply Tri-Flow bicycle lubricant (Teflon based)
     to same area and turn shafts in same fashion.
6.  Replace felts and tuning knob.
7.  Don't expect shaft to freeze up ever again. (unless you store the rig
     in your attic for 20 years) :-)

I have done this to no less than eight TT PTO sets over the years and the
problem has never recurred.

Tri-Flow is available at most bicycle shops.
