Box arrived, I separated parts and assembled easily enough. On problem was that one of the four clevis pins was missing (a larger size than most in stores, but tolerable). The pump arm was missing as well, so I emailed (the wrong place but I was directed to the right place (sort of). I moved around a certain Byzantine effect, though folks were polite. They wanted pictures of what is missing (Which ought not to prove much since all one would have to do if lying was remove the pieces before taking the picture). End result was that I was sent a new everything with no need to return the old one (a good thing because these are heavy). So worked out.
