Examine the gears to locate any timing marks on the gear set that indicate where the gears were lapped by
the manufacturer. Normally, one tooth of pinion gear is grooved and painted, while the ring gear.has a notch between two
painted teeth. If the paint marks are not evident, locate the notches. Proper timing of the gears is set by placing
the grooved pinion tooth between the two marked ring gear teeth. Some gear sets have no timing marks.
These gears are huntinggears and do not need to be time. Nonhunting and partial nonhunting gears must be timed.
