Solutions abound with rather difficult repair instructions using Ten-Tec’s special grease that holds things in place and provides the “correct” tension with which the tuning knob operates. Wow! What a pain all that can be.

Then I spray the PTO mechanism and slowly gently start to ‘work’ the knob. As things loosen up I continue to bathe the mechanism in the Tri-Flow lubricant. It will continue to loosen the TT grease and it will drain off along with the lubricant. When the gearing is sufficiently loose I let it drain off over night. Button it up and you are done.

In the grand scheme I don’t believe a tuning shaft ever gets turned as much as a clock motor before it fails, and gets the same repair.
