+ | **Another consideration**: | ||
+ | The position of the mark on the pinion gear to line up #2 cam is straight across from the slot in the back of the gear. \\ | ||
+ | This slot can be widened with wear and not line up perfectly with the keyway on the pinion shaft. \\ | ||
+ | The keyway is actually what #2 cam should line up with. \\ | ||
+ | So if the pinion gear is off a little from the woodruff key location, the cams can appear not to line up perfectly together (even though they are). \\ | ||
+ | So while lining up the pinion gear and #2 cam, there may be a fudge factor there also to consider when the dots aren't lined up perfectly. \\ | ||
+ | You can see that the pinion gear is installed to the right of the center of the slot in the third pic below. \\ | ||
+ | |||
