I understand what you are saying, I was suggesting that only one side of the backhoe frame should need to be removed to allow installing both eyelets. I was trying to save you from removing both sides of the backhoe sub frame - I may not be explaining it well enough.The pin is already installed and cannot be removed (or moved right or left far enough) to allow the eyelet of the check chain to be "threaded" by the lower pin because the backhoe subframe is blocking it from being removed.
