Looks like I shouldn't have used a petroleum grease as I guess there are soft seals in there. Done now
Some RV folks are saying vegetable oil on the shaft to avoid swelling that seal; think maybe coconut. Then there's a feller who tapped in Zerk fittings and uses a grease gun to fill up the entire blade cavity. Says no problem in 4 yrs. Thanks for the answers.
