[TenTec] help needed with 238B tuner dial

[N0RQ-lists]

My 238B tuner has a repeat problem.  The Inductor dial display ("dial
skirt", numbered 0 through 30) spins freely.  This does not stop proper
tuning, but it sure stops me from knowing "where" I am and makes my preset
tuning chart useless.

The first time it happened, I sent it in, and they fixed it, and it was good
for a while, but it has occurred again, and I'd rather not spend the $ if I
can do it myself.  I've been told it isn't overly involved.  The only
instructions I've seen, though, said:
The dial skirt is fastened to the gear train by a push in  bronze bearing.
The bearing has become loose. Loosen the set screw and remove the knob and
reseat the bearing.

OK, so I finally got the knob off, and was able to slide the dial skirt off.
By all appearances, the bronze bearing on the dial skirt is attached
solidly, but I see no notches or gears or anything that keeps it from
spinning freely.  And I don't know what is meant by "reseat the bearing".

Does anyone have detailed instructions on how to fix this?  It is fixed from
the front, or do I need to get inside?  (I didn't see anything inside that
was obvious.)

Tnx very much & 73,
