AndyMark transmissions at IRI

For those of us out of the loop, how would 45's shifters differ from the stock Gen2's?

From this thread (and in person at champs);

The drive base is somewhat modular. The guts of the drive module in the middle is an AM Shifter. We removed the sprockets, and added a gear and another reduction to the shaft that drives the middle wheel. Essentially, it's a direct-drive AM Shifter.

On the ends are wheel modules. These simply hold an axle for the outside wheels of the 6wd. Chains from the drive module axle power the axles on the wheel modules. We've got a neat-o sprocket/hub that works very well for this.

Since we have these "modules"... we have some options. We really like the 6wd setup, but if we had to do something else, we could.

It's similar to the gearboxes the "west coast drive" 4/22/60/254/968/980 have used over the years. I guess this opens up AM shifters to a whole new market.

You'd have to ask Andy or Mark to be sure, but I bet that's where the idea to expand the design came from.

EDIT: I have a question for AM as well... Is the output shaft supported well enough such that you could bolt the transmission to the frame, and mount a wheel on the output shaft that is cantilevered?

Similar yes, but with considerable differences. The 968/254 transmissions 06 and 07 transmissions feature larger gears for more reduction as opposed to an additional stage. Also, the 4/22/980/60 gearbox is a mesh shifting style; completely different. I suppose you were referring to the way they all face mount which is similar, yes.

From what I saw this would be possible, although I am not sure if the output shaft I saw would be long enough to do so.

I knew someone would call me on that... I was referring more to the concept/function than the internal workings.
