Yes, for some reason a lot of people think you're supposed to have a gap rather than a 0.1mm interference between the belt and idler.barnwerks wrote: Thu Mar 06, 2025 4:32 am Anyone notice in the video that the balance belt tensioner pulley installed is a timing belt tensioner pulley.
Also, the specification for clearance between the balance shaft belt and idler is 0 to a negative value. Meaning the idler should be touching the belt run or deflecting it upward slightly.
Looking for ArnnWorx or 9201 Tension Tool

It's been a few months and I found this post searching for an Arnnworx tool. Any update on your efforts to make a replacement tool?Tom wrote: Wed Mar 05, 2025 6:02 pm I am feverishly working on a replacement for the Arnnworx tool. Won't be ready for several months though. Different design but will work on all models and be more precise than the 3D printed tool. That said, the 3D printed tool is surprisingly accurate. Certainly better than the 'twist' method in terms of consistently getting it within the range Porsche spec'd, especially for newcomers with no 'feel' for how tight they should be.
