It is accessible after removing the white cover behind the pilot's seat. * * The screw shaft should be lubricated with lithium grease, I believe. If a 3 in 1 type oil is applied to the metal screw shaft, it causes the nylon bushing to expand. Over time, flap movement slows and the flap breaker starts popping due to the excess load. The cure is to tap out the nylon bushing until the screw shaft moves freely inside it. Turning the vertical drive shaft of my plane in de nylon bushing is difficult to be done by hand because of too much friction. To cure this problem, Paul advises to tap out the nylon bushing. But then my question is: which size of thread is in the bushing?* * * *My second question is: is a replacement set of shaft and bushing still available for the Allegro 2000?* * * *Thank you for your comments.* * * *Theo van Duin, France* *Allegro 2000* *71MM* * * ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message allegro-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Allegro-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/allegro-list Browse Digests http://www.matronics.com/digest/allegro-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
