Bought a 2017 Husky FX450 with this WP spring conversion on it. Can't seem to find any info on line at all about it. Interested in knowing what the preload adjustment range is? Hard stops on either end of adjustment knob so I can see how many turns I have to work with? I expect so but don't want to find out the hard way...... Strange that I cannot find any info whatsoever on it including WP website? Looks like a large number of vendors still sell it but no installation or user manuals available?
