Re: pic: Off-Season Kicker Design
We used an anti-backdrivable window motor, and attached it to parts of a toughbox (1 stage). We made an assembly that, using a 2" bore piston, separated the gears in the direction of force, so the piston held the two gears together when not kicking. This was after we were unable to release a dog gear, even after greasing it and pulling it by hand. I don't know if there are any good pictures of it, but if you're at IRI, you can come to our pit and ask us about it.
In a nutshell: We un-mesh the gearbox by attaching the motor side to a plate that moves to pull the two gears apart.
