Installed this week and tried to loosen after applying grease. A bad buddy or a bad grease gun that won't detach from the oiler! The grease gun was bought with the same purchase and couldn't get her to loosen the grease fitting! Tried all angles and finally tried to pull it off with more force than I expected. Something was wrong with one of the items! Luckily Revain customer service replaced them and let me return the grease gun and I bought a better one.
