I think several of us are breathlessly waiting for the next episode!

In the above picture it appears that the balk ring is significantly abraded. The shot today is after cleaning off much of the lubricant. What appeared to be scoring was apparently due to the lighting and streaking of the grease. Today's picture shows the ring and gear after some cleaning. I did test the balk ring with a kitchen scale and to get movement of the two ends towards each other required at least 10 pounds ( the scale maxed out; and I heard my wife approaching). moving the ends apart was very easy. I made this check after cleaning the part with carburetor cleaner which may have contributed to the excessive drag. i'll try repeating the test after applying some lubrication. The other picture shows what is in fact some abrasion of the governor/ speedometer drive gear. I am hoping that this can be cleaned up with a file. I'm also not sure whether this is a recent issue or preexisted the last rebuild.

The answer!!

With the very patient help of fellow Ford Barn member Gary Duff the problem has been solved. With the stationary gear plate removed and the solenoid , pawl and sun gear in place and the solenoid energized the pawl moves to the first notch on the balk ring. While maintaining electrical connection and the with the sun gear being rotated clockwise, the pawl drops into the deeper notch on the balk gear. When the adapter plate was put in place with the large snap ring and the above procedure repeated, the pawl would not fully engage. The attached pictures show the area of binding on the backside of the adapter plate.
There is a ridge which is catching and preventing the pawl from fully engaging. I will do some judicious filing to eliminate the problem. I will do a followup post when that is finished and the system is working properly. Again I thank everyone for their help with a very special thanks to Gary.
