The information on what is an "old" engine and the rectification process is all in JSB 012-1 dated 10/06. If this is followed then I believe the problem has basically gone away. There a couple of points I would make.: JSB 012 does not call for any sort of grease on the assembly and given that the joint relies on friction between the parts, why would you risk grease contamination? The bulletin calls for 24 ft lb (32.5 Nm) so using grease to achieve ultimate screw tension does not seem to be an issue. and There is a comment earlier in this thread relating to partial tightening to allow "local relaxation" then tightening to torque up to an hour later. Although this time period is consistent with the Loctite literature my experience with 620 has been that after an hour you will be tightening against the Loctite and not the bolt tension. This is implied in the revised prop flange attachment procedure in JSB 022-1 which says; "Fit the flange to the crankshaft & fit the screws by hand, then tension the screws using a calibrated torque wrench immediately" -------- Cheers, Selwyn Kit 66 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=271530#271530 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message jabiruengine-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/JabiruEngine-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/jabiruengine-list Browse Digests http://www.matronics.com/digest/jabiruengine-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.
