Should the tension pulley move?

[crackedfinger]

On my 500 (serp) the idler pulley, at tickover, moves with the lulling revs of the engine. Is this normal at all?

Have tried to tighten the bolt, moved a bit but had no impact on fixing the pulley.

Yes it's normal for the tensioner pulley to move slightly.

If it moves a lot then the belt may be a bit sus, belts stretch with age, when I replaced my last one, the diff between the tensioner position between old and new was noticable. The old belt was totaly FCUKED. and longer
