[R-390] Cam Synchronization

[wabate]

Hi.  I'm working on a newly acquired 390A and I've started with the 
mechanical synchronization.  I've worked on 390A's before but this is 
the first that is slightly off sync. Four of the cams were off no more 
than 1/8" so I decided to touch it up.  The other two cams were OK.  I 
adjusted three but I'm stumped on the 8-16MC cam.  That cam does not 
have a non-mar clamp on it.  Its riveted to the gear.  How do you adjust 
that cam?  The manual does not say anything specific about that cam.  It 
appears that the MC shaft controls it but I don't want to guess wrong 
and adjust something that I should not.  The 8-16MC cam is off about 
1/8" from where it should be.  Should I ignore it?  If I try to align 
that cam with the KC shaft, I get to the end stop before it lines up. 
Over ten turns stop readout of the KC shaft is within spec and the 
crystal osc. band switch is OK.  The intermittent switch drive is off 
about one tooth from where it should be but the the six position RF band 
switch alignment is OK.

Thanks,
