 In that position the oil pump drive gear has a lot of end play between the shaft shoulder and the back of the pinion gear as shown in your picture. \\ In that position the oil pump drive gear has a lot of end play between the shaft shoulder and the back of the pinion gear as shown in your picture. \\
 When the engine runs the drive gear is thrust against the back of the pinion gear. \\ When the engine runs the drive gear is thrust against the back of the pinion gear. \\
 So if you time the pump with the gear in the opposite direction pushed against the shaft shoulder it's very easy to get the lineup off a tooth. \\ So if you time the pump with the gear in the opposite direction pushed against the shaft shoulder it's very easy to get the lineup off a tooth. \\
 If you are going to pull the pinion gear off you'll need to determine the position where the drive gear will end up with the pinion gear installed. \\ If you are going to pull the pinion gear off you'll need to determine the position where the drive gear will end up with the pinion gear installed. \\
