38-690 RF Chassis Removal
#1

I recently inherited a Philco 38-690-125 Run 4, and I am hoping to get it working again.  I have gotten the power chassis re-capped as well as changed out some resistors that were out of spec.  That was all fairly straight forward.  Now I am onto the tuner chassis, which seems to be a bit more involved.  Right now I have it on my bench and from what I have read in other 690 threads it looks like the middle part where the variable capacitor is located can be removed.  There appears to be some capacitors that will be pretty impossible to get to unless I do this.  I am confident in my electrical troubleshooting but am hoping to not disturb the "mechanics", or at least as little as possible.

My question is what does it take to remove this section?  Do I need to completely disassemble the front dial to remove the shaft going through this section?  Basically what is the minimum I need to take off / decouple before the middle section will be able to be removed?
