yes, with robot on the gearbox, we coulldn't remove the gearbox, and we didn't know tha we needed a tool for removing it. we opened 3 screws and could move the robot partly but we could never remove the robot. so we decided to take the whole engin down. it has been a hele to make it. tomorow we will change the clutch and cam belt, I am very concern about the robot, since we have open it and tried to remove and I saw even sign of strike on it. what should we be careful when we put the part back tomorrow?
