Dissasembled one of my rocker boxes to clean it up. Didn't pay real close attention to order of washers since manual had a good picture. When I reassembled...i noted that the spring preload on the side with the acorn nut kind of jammed up so that there was no preload at all. Took it apart several times and concluded that the washer was hitting the little step on the shaft and pushing the spring up against the side of the box. Appears that the washers have to be on the outside of the spring to work. The other rocker box ( which may have been worked on by PO ? ) has them that way. Is the manual wrong or am I missing something?
