Hi Captain, I don't know if your tuning assembly with Fine and course tuning is the same as my 37-116. I took mine apart years ago and I remember there were 3 ball bearings that went around the shaft and another that was at the end of the shaft with a small Spring. There is an ever so slight size difference between that end ball bearing and the other 3. I am guessing possibly you have one of the 3 transposed with the end one. I know Harbor Freight sells a kit with various size ball bearings and also kits of various size "C" or "E" clips too if you are in need!
