I'm trying to remove the oil screen on my wife's 2003 Monster 620ie. I've removed the external plug and the filter seems to have a 14 mm hex keyway. The manual states release the screen and withdraw to clean. Is the filter (14mm keyway) just a threaded part with normal right hand threads? I can't seem to budge it and don't want to mangle anything. The plug was extremely hard to remove, I really had to bang it pretty good with a hand impact driver. The drain plug was also very hard to remove. Everything on the engine seems very tight and besides questioning if there are any tips for removing the screen, I wonder if I should use anti seize compound or locktite on these connections. Thanks in advance for any suggestions.
