[R-390] Cam pins

[Drew P.]

Note that for reinstallation of the taper pins, they must must be driven until they seat, so that there will be no relative motion between cam and shaft.  They will otherwise elongate the holes in the soft brass of the cam, and no amount of driving the pin in will correct this.

I had a cam/shaft assembly with such a malady.  I drove out the pin and removed cam and shaft.  I reassembled the "bad" cam to the shaft with the pin (to the extent possible) and Loctite 271. I laid the assembly on a machinist's surface plate such that the cams' "valleys" were facing down, and twisted the bad cam to alignment with the good.  After the Loctite had cured, I then drove out the pin from the "good" cam and reassembled cam/shaft assembly into the RF deck with the pin.
