Feel free to add to this or correct anything that I say that is wrong and I will edit and correct as needed.
I had the opportunity while I had my motor and trans apart to take a couple pictures and explain something about what those 3 little springs in a "DUNEABLE" override actually do.
Many people think those 3 little springs do nothing. They think that they may have to try to keep a gear pushed against a huge amount of force. That is actually NOT what they do.
Those little springs are only there to keep the slider gears in a neutral/middle type position and not engaging cogs left or right of it that would be spinning in the wrong direction or speed depending upon what gear the transmission is in. Of course helping to not break gears or wear/bend shift forks.
It is important to have the springs length and tension adjusted so as to have the slider gears sort of floating in between the other gears when not engaged so if the transmission is turned backwards by hand there will be no binding. The transmission should turn freely by hand both forward and backward in each gear.
When installing an override or replacing shift forks if the transmission will only turn backward about 3 turns in any gear before binding then you have a spring not holding the slider gear away from the gear that the dogs on the slider gear are supposed to miss.
