Just about to start on a very clean KWM2-a project, absent any rust or corrosion. Need advice on the initial steps of getting behind the face plate of the rig. I have a Collins manual, but it is sorely lacking in the things that would normally be in a repair manual, i.e., exploded parts pictures of sub-assembly for dial mechanism.
The first issue is that the dial spinner knob shaft - the PTO?-seems to bind, or slip - one can turn the knob, but the dial will not move more than 2 khz in either direction- and knob seems to be slipping on the shaft. There seems to be no mechanical action within the pto itself that would cause binding, and so, am looking at the dial gear drive mechanism and/or a stuck dial cord. Any surprises? - hidden springs, parts that jump, dial cords that are impossible to re-install if taken off a wheel, etc.?
