  • Electrical: Converting 57 Golden Hawk Tach from Pulse Drive to Electronic Sending Unit

    I just finished converting my 57 Golden Hawk's tach from pulse drive to electronic sending unit. I used a 63 GT Hawk tach mechanism with the related sending unit and swapped over the face and needle from the 57 tach. It works and looks great. A video showing the modifications is attached below.

      Looks great. The only thing I would do different is I would never tap the bezel back on. the impact shock can damage the instrument. I have a way of rolling the bezel back on with no impact.

        Really Excellent work Neil, that is a very good way to update these old usually failed Tach's. Many Hawk owners cannot find a working Distributor Drive, so it's a good riddance.

          I agree. Rolling the bezel on is the preferred method. Since I didn't have that equipment I just went slow and took multiple light taps with a punch to get it on. Fortunately, no damage to anything. If I did more gauges I would invest in the tools to roll the edge but I don't do this very often!
