Are threads clean and free of oil or rust when you apply loctiteIJ If not, maybe you should consider loctite primer. Also, some loctite products dont work very well unless at least 1 surface is plated. If thats the case, you need primer. Some guys use an aerosol cleaner which may not do what you need done which is to get the loctite to cure properly. I wish I had a better answer but I havent had similar problems with my feed reverser which is surprising for all the use it gets in soys.
