Since the gear broke the minute we put it in the gearbox we decided that we would just buy a whole new gear box. The gear box arrived and we installed it, sort of we tried to install it. The place where the gear box is attached is reversed and the holes where you put the screws are to close together. So now we have three options;1. Send the gearbox back and ask for the right one, 2.Grind down the attachment surfaces and insert a metal plate that is the right size, or 3. take out all the parts of the new gearbox and put them in the old gearbox case. We will probably decide what we will do at our next meeting.
