[R-390] Strange BFO backlash explained!

[Flowertime01 at wmconnect.com]

Tim,

Is the BFO reactor shaft really supposed to have this much (I'd guess
1/32") wiggle in and out?  I'd be very surprised if so...

-----------------
Tim,

We do expect the BFO shaft screw in and out as you tune it.

We do not expect the shaft to have any slop moving in and out so there should 
be no backlash as you adjust the BFO.

I can believe the BFO bushing is worn to the point where you have the 1/32 
free play in your BFO reactor shaft.

Like you said the bellows coupler can be adjusted to place minimum force on 
the reactor shaft and the IF deck BFO shaft bushing.

I believe you BFO suffered from years of miss adjusted bellows coupler and 
that has caused a lot of wear on the reactor can bushing and thus giving you a 
lot of slop.

If you can live with it OK. If not, it is not real hard to do a reactor can 
replacement. The reactor cans did die and were replaced.
