[R-390] RF subchassis separation

[Mark Richards]

To Chris, Bill, Barry, Norm, Roy, Bob... thank you!  I am overwhelmed 
with the number of replies and excellent thoughts.

In summary, the shaft is held in place with a countersunk screw 
(possibly philips head?) screw.  It is possible to gain access by 
separating the chassis.  Question is: how?  It appears removal of the 
cam assembly (as a start) is required, and this seems a frightening 
proposition.  Chris, can you give us some hints on how you got these apart?

Tried to tighten the shaft by rotating.. even with some pulling tension 
to friction-lock the screw, allowing the threads to take. No joy.  My 
guess is that whatever corrosion or chemical bond exists has formed with 
the shaft in the loose position.
