Shimming a starter motor on a 350 Chevy engine is a relatively simple process, but one that requires a good understanding of the mechanics of your engine. The starter motor is responsible for turning the engine over and providing the spark to ignite the fuel mixture in the cylinders. When the starter motor is not properly shimmed, it can cause the engine to run rough and the spark to be weak. Understanding how to properly shim your starter motor is an important step in maintaining your engine and keeping it running smoothly. Let’s take a look at how to shim a starter on a 350 Chevy.

What is Shimming?
Shimming is a process of adjusting the distance between two components by adding a thin metal or plastic shim. In the case of a starter motor on a 350 Chevy, the shim is placed between the starter motor and the flywheel or flex plate. This creates a gap between the two components and allows for a slight movement of the starter motor when the engine is running. This movement helps to reduce the amount of wear and tear on the engine components and allows the starter motor to run more efficiently.
Tools Needed
In order to shim your starter motor on a 350 Chevy, you will need the following tools: a wrench, a ratchet, a flat-head screwdriver, a pair of needle-nose pliers, and a set of shims. You may also need a piece of cardboard or a flat surface to work on. Additionally, you will need to have access to a manual or guide that contains diagrams and instructions on how to properly shim the starter motor.
Steps to Shim the Starter Motor
Once you have all of the necessary tools, you are ready to begin shimming the starter motor on a 350 Chevy. The first step is to remove the starter motor from the engine. This is done by loosening the bolts that hold the starter motor in place and then carefully lifting it out. Once the starter motor is removed, you need to inspect it for any signs of wear or damage. If there is any damage, it should be replaced before you attempt to shim it.
The next step is to place the shims between the starter motor and the flywheel or flex plate. This is done by inserting the shims into the gap between the two components. To ensure that the shims are properly placed, use a ratchet to adjust the gap until it is just right. Once the shims are in place, tighten the bolts that hold the starter motor in place.
Finally, you need to test the starter motor to make sure that it is shimmed correctly. To do this, turn the key in the ignition and listen for the starter motor to engage. If it engages without any problems, then the shimming was successful. If you experience any issues with the starter motor, you may need to adjust the shims or replace the starter motor.
Conclusion
Shimming a starter motor on a 350 Chevy engine is a relatively easy process, but it is important to understand the mechanics of the engine and to use the proper tools. By following the steps above, you can ensure that your starter motor is shimmed correctly and that your engine is functioning properly. With the right knowledge and tools, you can easily shim your starter motor and keep your engine running smoothly for many years to come.
