What causes a starter to slip?
CAUSES OF FAULTY STARTERS: CAUSE OF FAILURE Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically. Single-pinion gear, starter pinion or freewheel damaged.
How does the Bendix gear on a starter motor work?
This video is all about the Bendix gear on a starter motor. This is the gear that rises up and engages with the ring gear around the flywheel. When things go wrong with this gear it can not rise up or disengage before the motor is started. This video looks at how these gears work and how to fix them when they go wrong. Loading…
Why does my starter not engage with the flywheel?
You can hear the starter spinning, but it’s not engaging with the flywheel. What could be wrong? The most common causes why your starter won’t engage with the flywheel is low battery voltage, a faulty starter solenoid, faulty starter motor, and wiring problems.
What to look for when your car starter won’t engage?
The starter pinion gears engage it to start the engine. What you should be looking for in a faulty flywheel are worn or damaged gears. While the car is on neutral, rotate the crankshaft using a ratchet. As you move it, watch the behavior of the flywheel.
What causes a starter to spin without contact?
Free spinning is when, for some reason, the starter gear is just spinning without contacting anything. The sound is similar to that of a small drill spinning. When this happens there can be an issue with either the flywheel or the starter. In the case of the flywheel, the teeth might be sheared off in one area, or off the entire flywheel.

Why does the starter spin but not engage the flywheel?
The Bendix gear is mounted on spiral grooves in the starter shaft and held down (when not engaged) by a spring. When the starter motor is engaged it starts to spin the shaft and the gear can’t accellerate that fast so it slides up the grooves until it engages the flywheel. That is inertia.
Why is my Bendix not working on my flywheel?
The lugs on the battery cables can get corroded inside where you can’t see it and cause that problem. The shaft that the bendix rides up and down on must be clean and lightly lubed. You should be able to manually turn the bendix up to engage the flywheel without it binding.
