The cover is removed by jamming a screwdriver or a pry-bar inside the lip on it and twisting. When you take it off you'll either find the bearing is buggered, or someone has tightened it down with a bent bolt or a piece of debris trapped beneath that put it at that wacky angle.

I'm wondering if the tensioner is worn out, not putting enough pressure on the belt?
It would be very hard to lift- you really can't lift it without a tool.

well this is a non-groove idler pulley.

25NM is fine, remember you are bolting into aluminium so not too tight.
