1. Remove the starter from the vehicle.
2. Inspect the ring gear for damage. If the ring gear is damaged, it will need to be replaced.
3. Install the starter shim on the starter motor. The shim should be placed between the starter motor and the bellhousing.
4. Reinstall the starter in the vehicle.
5. Tighten the starter bolts to the specified torque.
6. Test the starter to make sure it is working properly.
Here are some tips for shimming a starter:
* Use a shim that is the correct thickness. If the shim is too thick, it will cause the starter to bind. If the shim is too thin, it will not provide enough clearance between the starter and the ring gear.
* Make sure the shim is installed correctly. The shim should be placed between the starter motor and the bellhousing, and it should be flush with the surface of the bellhousing.
* Tighten the starter bolts to the specified torque. If the bolts are not tightened properly, they could come loose and cause the starter to fall off.
By following these steps, you can shim a starter if the ring gear is tearing up. This will prevent further damage to the starter and the ring gear.
