Here is my idea split shifter solution, Version #1.
I say Version #1, because the assembly sticks out under the back seat area more than I would like for it to. I was trying to keep the all-thread as close to traveling a straight line as possible and maintain a short travel with the shifting handles. I think I can get it tucked under the seat better, but for now this will work. I’m ready to get this thing operational so I can drive it!
There are two outer round tubes (left and right) that pivot over a small diameter inner tube that is capped and tapped and bolted to the mounting brackets that mount to the T-20
I use all-thread and compression springs for the final links. The all-thread pass though the shifting pin that I made out of tool steel, and works also as a over center stop when the seat brace is mounted.
Here are some tubes that I made that bend up over the frame and under the floor board brace, to connect the handles to the shifting assembly mounted to the T-20. They have bolts welded to the ends of the tubes to allow adjustments to be made at the tie rod ends. I’m not sure if the tie rod ends I have are the best solution because they allow the tubes to move a little more side to side than I would prefer. My next version I might try to use fixed ends.
All in all I’m pleased with the way it shifts. I have plenty of places to make adjustments to dial in the travel of the selectors with little of movement in the linkage. I hope with my next design I can get it more compact.
With all that being said and me reading over it, I hope it makes sense to everyone. I can envision it, but I sometimes have trouble getting it to words so everybody can understand whats trapped in my head.
I would also like to note that I don’t think this would be possible if I was going to run the factory middle axle brake.
I hope this will help others out that don't like thier current set-up, being the cables or the type that doesn't allow split shifting, to thinking. I counldn't have done it without this site. The pictures from other peoples' manchines really got the wheels turning. So get out there and take somemore pictures, somebody needs to see what you got.
TaDa!
