9244 Thin Wrench

This 27mm wrench is a step beyond Porsche's wrench. It is needed to adjust the cam & balance belt tension. It is made with the latest water-jet technology and of cold rolled steel. It has a black oxide coating and features a 6 inch handle with a thin, yet oversized, head. The thin part is needed to get under the roller's off-center pivot nut and the oversized diameter makes the wrench strong and helps to prevent the belt from riding up on the wrench edge.  Note: compare my price for this tool to Porsche's price of  $56.00; also if you're considering this wrench from other vendors, look closely at their pictures, some are Chinese stampings or  re-cut bicycle wrenches. They are not nearly as strong and do not have a correctly bent handle to reach the cam belt's off-center roller.  

One side note here... In the first few months of 83, 944s were equipped with a "small nut roller." For the most part these early rollers have disappeared but occasionally one of the old rollers will surface. I suspect they are being sold as "new old stock" in hopes that buyers will not notice. If you order new rollers, settle only for the later style, 27 mm rollers.
