Hope this is useful information for those having trouble with shifting on your 66 or 86 series. We've also recently had trouble shifting into reverse and after oiling up the shift linkage it helped dramatically.
In semi tractor you have a clutch brake also ,so when you adjust the main clutch it's good to check brake also 👍 . Not to change the subject , they advertise flashlights and lanterns on TV that the military is supposed to use, may lighten up your videos better 🎆 now you can rock and roll 🚜
It's none too bright in that barn, currently, it needs triplex re strung to it. Lightning struck its wire. Then, we may have netter lighting, not to mention, most things get fixed on dreary days.
