Would the weather have any influence on the outer otb going bad? I have just replaced the outer one by my first gear. It has been rather cold here (30-40) during the day. If I read your pervious post correctly I can clean out the old bearing lube it back up with 3-in-1 and then place it back on? I have saved all of them when i took them off. They all looked very greasy around the outsides.
"all"? How many have you had?
I'm still running my original that I got when I installed my LRP28 with the LST2 2-speed assembly. mine started life as an aftershock, so I had to upgrade when I got more power. Shelled the AS one out by tank 6 of break-in with the LRP.
The cold combined with the heavier grease/oil that is in it in stock form would make them more prone to hang up and slip. Clean them out with DA and lube them up with 3-in-1. My only suggestion would be to pull it off and do this at least once a gallon to help avoid slipping and wearing issues due to lighter oil. By "at least", I'm quietly suggesting 2 times per gallon.
That's about how often mine gets pulled, cleaned and re-lubed. I've probably ran around 4-5 gallons through it and it worked just fine last season. Shelved it for the winter. Ran the savage instead.
