you need to run the engine with the case off,i would say leave 2 bolts in the case and start it,then carefully take the case off whiles its running and have a look at what its doing.the belt shuld be sunk right inot the variator at low revs and climb outwards as its revved and also at the same time the belt should sink into the middle of the rear pulley .
