Heres the gearbox setup from my Legacy h10, which has the intermediate gearshaft and gears. There is lateral slop in the intermediate gearshaft that looks like it could present a half a gear( or less) mesh not unlike what is seen on diesel locomotive trucks. At the same time, the brass gear is meshing on one side of the worm
The brass colored gear is driven by the worm. The smaller gear next to it turns the larger axle gear. This is where I say all of the torque is on one side of the intermediate shaft.
This photo shows the intermediate gearset pushed all the way to one side of the gearbox about.
In this photo I pushed it up towards the axle gear. I guess the question is. Which way does the worm shove the gear when the loco is in the forward direction, so it meshes more completely or only partially?
