It has also been brought to my attention that the set screw location has moved from the intended location in the plastic sprockets. This may also contribute to issues with the mast and sprocket. Masts should be fully seated into the sprocket and retained in that location by the set screw. If the recess in the mast is mislocated, due to the changed set screw location, causing the mast to be less than fully seated, additional grinding on the mast recess may be a good idea to get the fully seated mast as designed.
The set screw location and mast retention recess issue has been corrected in current production.
