I had a few questions about how I was going to modify the 20v Tensioner, so here is my off the cuff ideas.
1st - If you are not running a Dist and plan on running the 16v/aeb IM shaft 43T gear, then you can simply use the 16v "fixed" type tensioner with the 157T custom belt and call it a day. No need to read on in this post.
If you are running Dist (Which I was going to), you have to run the only available "correct Tooth belt" at 158T (159T would be perfect) which will not fit with the 16V tensioner. You must use the 20V variant which allows you to use the 158T belt.
Here are two ideas that I had for mod'ing the 20V tensioner to make it "Fixed" instead of the hydro self-adjusting. Even though I am not running dist, I may still use the 20v type pictured and "affix it" as shown.
