Quoted from yonkiman:
You seem to really want to try to do it that way, so give it a shot. If it looks like anything's getting damaged, stop and unscrew the pin.
Is not that I really want to do it this way, its just that I know it will be a PITA to screw that arm back to the lifting mechanism with the ramp back in place since I will have to maneuver the arm with a pair of pliers under the ramp and basically you can't really see what you are doing. Am I correct here? Is it difficult to screw the arm back? That is why I wanted to avioid removing the arm.
If I remove the arm, what will happen to the mechanism that holds the arm? Will it stay up or fall down?
