I've been using 5 different Currie motors ver the past 5 years. I have removed the drive gears n each oh them several times and I have never had one come loose. I would not recommend loctite for this application. But if you feel you must then be sure to only use it on the threads and not the actual gear. If you ever need to remove that gear the loctite will be a PITA even if only on the threads. Bob
