I was working on an LX665 today, and I had to pull the linkage plate that controls the hydros. When you lift the seat its the yellow plate on top of the hydros that slides front and back when you move the sticks. The plate has a large bolt and spring on the rear of the plate. THe spring pulls the plate back to neutral when you leave off the sticks. Anybody have tricks or tools for compressing the spring so that you can screw the bolt back in? Its a real bear to do....
