I clean all the grease out of the motor and gearbox, and then fill all the teeth in planetaries, ring, and sun gear with grease, and put it back together. I’ve got gearboxes with well over 500 flights and no abnormal wear. At about 500 flights, the needle bearings are definitely worn, and easy to replace. My micrometer says the drive pins on the output shaft are unchanged, and the ID on the planetaries is unchanged.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Regards,<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Dave<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> nsrca-discussion-bounces@lists.nsrca.org [mailto:nsrca-discussion-bounces@lists.nsrca.org] <b>On Behalf Of </b>Scott Pavlock<br><b>Sent:</b> Tuesday, July 03, 2012 7:04 PM<br><b>To:</b> NSRCA Discussion List<br><b>Subject:</b> [NSRCA-discussion] Neu Gearbox Grease Question<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So it's my first time attempting to grease the gearbox on my Neu F3A, and I have a question about a specific part of the motor. <o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>The area around the center of the motor where the main gear comes out is full of grease; quite a lot of it.
