This leads me to ask two questions:</font></div><div class=""><font color="#38571a" class="">1)<span class="Apple-tab-span" style="white-space:pre"> </span>Has anyone had this done or heard of it being done and if so any cautions or suggestions or lessons learned?</font></div><div class=""><font color="#38571a" class=""><br class=""></font></div><div class=""><font color="#38571a" class="">2)<span class="Apple-tab-span" style="white-space:pre"> </span>Has anyone tried to use the Viton Seal on a crank that has had the scroll machined off and what has been the end result of this experiment, or would it be better to just use the now old "lip seal" and tighten up the carrier and lip seal and shorten the spring a bit to try and grip the 2.50 diameter surface a bit closer.?</font></div><div class=""><font color="#38571a" class=""><br class=""></font></div><div class=""><font color="#38571a" class="">Any thoughts, cautions, theories, etc any of you have or could share (either via the list or privately) will be most appreciated.
