how to tell if its -2?
I thought I remembered from somewhere that the part number suffix identified the cam gear ( the "H" after 25 or the "B"). I looked in the PET and there is a part number for "camshaft with wheel -2" but that's for the assembly I believe. Anyway that assembly part number is 021.109.017 M and you can see the part number for the wheel is xxx.xxx.111.
On the other hand, the factory workshop manual says on pg 26.2-2/1 that there is a
number stamped on the side facing the camshaft -1, -2, 0, +1, +2, etc
