Removing High Speed in AM Super Shifter

We simply locked down the pin to low gear with New spacers and the pneumatic cylinder holding plate. All you have to do i bring new bolts and spacers to the competition. Remove all cylinders and pnuematics that are no long needed, and put new spacers in place and bolt them down. I'll try and find a picture or a CAD to show you.

EDIT: Here is a picture of the modification that maybe able to be used on a SuperShifter

Thanks guys. I think were gonna attempt the spacer idea because we already use the spring return air cylinders and we just want to cut as much weight as possible. Removing the gears and all associated air is the main goal and we think the spacer is the best idea. Hopefully it will give us enough weight to change our arm

I think you can also use a bolt and nuts to hold the "shift lever" to where you want it (similate the pneumatic in or out).

I think the fitting where the pneumatic connects is a 1/4-28, so use the right bolt!

The low gear is really low - usually close to 5 - 7 fps. That is really slow.

If you have the money, why not look for a solid toughbox gear reduction you like for a quicker fix?

This. If you want a good, one speed gearbox, use Andymark's CIMple box that came in the kit. It's not only a good one speed, but it's also lighter than the AM SS, so you'll not only get your preferred speed, but loose robot weight in the process. It's a win-win scenario.

Final speed depends on your wheel size and any output ratio from chain/belts. In 2010 when we locked our 2 speed, we put it in high gear and increased the final chain reduction to obtain a speed of about 9 feet per second.
