This is fun!! The issue for many is that they think of the 14 tooth spider gears as having some bearing on the ratio, they don't, they are just there to compliment the 2 big gears. Now this is where we need someone clever with a 3D printed and a CAD / CAM program to make some plastic gears. BUT...

well I think number of teeth is important but this can not be thought of as normal gear ratios. if the driven gear was 26 teeth and the fixed gear was 22 teeth, the reduction ratio would be less than 2:1 but what would it be? and could it be done cheaper and easier than R & P swap? I also wonder...

no, that's not how this works. if it was the ratio would not be 2:1 like it is.

spider gear size has nothing to do with the ratio, that is set solely by the 2 large gears. how much larger does adding 2 teeth to a already 24 tooth gear make it? yes they would contact different areas of the spider gears, I just don't know it there is room or not.

I don't yet agree that it would bind up, why would it? It may be that the 2 gears would need to have both even numbers of teeth. OK I am not sure this will not work, you have a driven gear and a fixed gear with the spider gear assembly fixed to the hub. If you increase the driven gear and...

Hi, sorry that is not always true. The ratio is that of the drive gear and the fixed gear. So the axle drives a bevel gear and there is a fixed gear on the axle housing with spider gears fixed to the hub. If the 2 gears involved are both 24 tooth like I think, it will be 2:1 reduction and turn...

OK so these are not planetary but spider gears like in the diff. Could planetary be installed in place of this whole setup? Why not?

does the FMTV have portal axles? Can you change the gears in the hub? I can have gears made pretty cheap.
