Besides the clearance of the starter pinion, you need to take into account the distance the pinion must move before it enters the ring gear. Not taking the time to make sure these measurements are correct can also lead to starting problems for your engine.
“At rest, we recommend that the pinion be .10-inches away from the ring gear. There is some room for leeway here but we do not like to see less than .06-inches and no more than .14-inches. This measurement has a significant role in the way the solenoid advances the pinion, ensuring that the pinion rotates correctly into the ring gear and main power is applied at the right point in the cycle. If the pinion is too close to the ring it may collide and not allow the pinion to enter. If the distance is too great the pinion may have too much rotational speed or, at the extreme, may not have enough travel to fully engage the ring gear,” Meziere says.
By making sure you have set your starter up correctly you will boost your engine’s cranking ability, and avoid issues like broken teeth on a starter or the dreaded no-start situation at the ready line.
