Kevin, the spring in your illustration, which is drawn over my photo, needs to be there. I believe there is supposed to be s spring that goes over the Rod, but when I pulled the pin out of the tension lever, I did not see a spring fly out.
I ordered the parts from Denny, and he is sending me a schematic drawing of the chuck head, so I can see the break down. Thanks again for all your help, I'll let all you guys know how the fix works, when i get back on the air.
