[TenTec] PTO - mechanical problem. help!

[Dr. Gerald N. Johnson, electrical engineer]

Lumpy grease on the screw?

In my Corsair's PTO it tuned poorly going down compressing the spring,
there was a great deal of slip in the vernier because of a deep groove
worn (crooked too) by the balls. A new race, knob shaft and grease job
fixed it. The PTO frame does not make the race settle perfectly
perpendicular to the shaft.
