[R-390] Removing Megacycle Change shaft

[rochep at comcast.net]

I have read it over and over. Here is where I am in removing the panel. In Chapter 10 Step 15 is where I WANT to be. Step 16 shows how everything looks before I remove the panel. In STEP17 there is a screw just under the Teledyne nameplate; it is not there in Step 16. Must this screw be removed before I can pull out the front panel?

I dont know if you can get see this. Now what? I see how to remove the KHZ gear but not sure about the clutch disk and the “gear” above it.
