pfw_dfw Cams don’t get indexed? They are geared to each other. Only one cam has the timing belt contact it. The other is the injection pump. Biggest issue I see when these get brought in is cause how the timing belt tensioner gets reset. That has to get aligned with the dot between the small fork window when prying it. Just pull cover back off. Everything has timing marks and so does the new belt. Take your time and make sure they are all on and then pry that tensioner into position, hold it, and tighten bolt. And also the special tools, if that’s what you meant were ordered, can only go on when you have the motor in TDC.
