- | KE5C made a series of photos detailing how to get to the encoder board and replace an encoder (http://www.ve7tk.com/Orion%20RIT%20Encoder%20Replacement.pdf). This is a very good starting point. I've listed some details I had to deal with replacing them all. | ||
One additional thing I ran into: The VFO A and B encoder shafts pass through a bearing. The knob screws had been tightened down so tightly, that a 'nick' was left on the shafts; large enough to not allow it pass through the bearing. I had to polish this down to get these encoders out. | One additional thing I ran into: The VFO A and B encoder shafts pass through a bearing.
