Re: 56mm Banebot problems @ Championship

We didnt see any noticeable problems with them, but to be safe we decided to take them off our robot and replace the carrier plates after our last practice round on thursday. This was the worst decisision ever! It took us 3 hours to take off the gearboxs, they keys and sprockets had gotten stuck on the shafts and we ended up having to make a little tool to press them out. When we did get them off there was no visible damage at all inside the gearboxs (we were running only 1 CIM). We replaced the plates anyways and put them back on the robot. We were there until 8pm on thursday and spent the first 2 hours of Friday putting it back together. When we got it all running again the right side kept binding up and it made it real hard for our driver to go straight and turn at all. So we took it off again during a 2-3 hour break between matchs, this time we didnt remove the shaft from the drivetrain but just the motor and most of the gearbox. I went arround and asked about 15 teams for a gearbox until I found one that had a spare (most teams had already given them away to other teams). We ended up not using it because the inside of the gearbox worked fine after we cleaned it out, so i gave it back on Saturday (Thanks 1732!).

What a nightmare.
