[F500] Tours and motors

[Jeff Blumenthal]

Mike:
 All last year I mentioned to Lynn that the secondary might be his problem. I
know that he had it worked on several times.  I'd also look very carefully at the
bearings on the jackshaft. I have a spare Polaris secondary that I'll bring with
me to the tour. You can try it if you want....Should only take about 1/2 hour to
change it.
