bork 0 #1 Posted November 2, 2009 Dont know if the threads are too rusted or what . I cant seem to get a 3/8" nut on threads. I dont want to force and make worst. Does anyone know what thread they are for sure? So I can clean up or recut. Share this post Link to post Share on other sites

bork 0 #4 Posted November 3, 2009 Mine looks like a course thread. I was hoping someone could unscrew theirs easily & try a 3/8" course thread nut. Hoping it would screw right on . If it does then I know I need to work on mine to make a 3/8" nut fit. Via file or tap or what ever. Before messing up knob. Share this post Link to post Share on other sites
Sparky-(Admin) 23,138 #5 Posted November 4, 2009 The shifter on my 1983 C-85 is a 3/8ths course thread. I didnt check the hi/low shifter. I know its not the right vintage but I dont have any 1967 tractors. Mike........ Share this post Link to post Share on other sites
