My apologies. The idler pulleys on a '97 are installed with hex head bolts. You can get between the frame and the pulley and remove the bolt. The new pulleys come with a torx bolt. Most NG900ers discard the new torx bolt and use the original hex head bolt. The tensioner pulley has a torx but it's rarely replaced in DIY world. I'm guessing that in '98 they went to the new torx-only design. Since Saab mechanics already had a special tool (guessing) for the tensioner, so it was actually easier for them (and the factory, no doubt) to use a torx. I'd expect that if you put a torx bit in there you could get a 1/4" wrench on the bit and loosen it that way. It will have to be a short bit though since the bit will get pushed back as the bolt loosens. Maybe just break it free then use long nose pliers.
