Cummins engines use a variety of starter motors to initiate the engine's operation. These starter motors are designed to provide the necessary torque to crank the engine and start the combustion process. Here are some common types of Cummins starter motors:
1. Direct Drive Starters: Direct drive starters are the most common type of starter motor used in Cummins engines. They are directly connected to the engine's flywheel ring gear and provide the necessary torque to start the engine.
2. Gear-Reduction Starters: Gear-reduction starters are another type of starter motor that uses a gear reduction mechanism to increase torque output while reducing the speed of the starter motor. This design is often used in engines where high torque is required for starting.
3. Pre-Engaged Starters: Pre-engaged starters have a solenoid that engages the starter motor pinion gear with the engine's flywheel ring gear before cranking. This design ensures smooth engagement and disengagement of the starter motor.
4. Inertia Starters: Inertia starters are designed to store rotational energy in a flywheel or other mechanism to provide a quick burst of power when starting the engine. This type of starter motor is often used in applications where rapid engine starting is essential.
5. Permanent Magnet Starters: Permanent magnet starters use powerful magnets to generate the magnetic field needed for the starter motor to operate. These starters are known for their efficiency and compact size.
6. High-Torque Starters: High-torque starters are designed to deliver increased torque output compared to standard starters, making them suitable for engines with high compression ratios or in cold weather conditions.
7. Cold-Start Starters: Cold-start starters are specifically designed for use in cold climates where engines may have difficulty starting due to low temperatures. These starters provide additional torque to crank the engine in cold conditions.
8. OEM Starters: Cummins also offers original equipment manufacturer (OEM) starters that are specifically designed and tested to work seamlessly with Cummins engines, ensuring optimal performance and reliability.
These types of starter motors may be used in various Cummins engine models depending on factors such as the engine size, power output, application, and environmental conditions. Each type of starter motor has its own characteristics and advantages in terms of starting performance and durability.

Price range of Cummins Start Motors
As of my last update in September 2021, the price range for Cummins starter motors can vary depending on factors such as the specific model of the starter motor, the application it's intended for, whether it's new or remanufactured, and where you are purchasing it from.
Here is a general price range for Cummins starter motors based on typical market prices at that time:
1. Standard Starter Motors: Standard starter motors for Cummins engines typically range from $100 to $300 or more, depending on the model and specifications.
2. High-Torque Starter Motors: High-torque starter motors designed for heavy-duty applications or engines with high compression ratios can cost anywhere from $200 to $500 or higher.
3. Remanufactured Starter Motors: Remanufactured Cummins starter motors, which have been rebuilt to meet OEM specifications, may be available at a lower cost compared to new starters. Prices for remanufactured starter motors can range from $50 to $200 or more, depending on the specific model and quality of the remanufacturing process.
4. OEM Starter Motors: Original equipment manufacturer (OEM) starter motors specifically designed for Cummins engines may be priced higher compared to aftermarket options. Prices for OEM starter motors can range from $150 to $500 or more, depending on the model and features.
5. Specialized Starter Motors: Starter motors with specialized features such as cold-start capability, high durability, or rapid cranking performance may be priced at the higher end of the range, potentially exceeding $500 based on the specific requirements.
6. Performance or Racing Starter Motors: If you are looking for high-performance or racing starter motors for Cummins engines, prices can vary significantly depending on the brand, features, and performance specifications. These starter motors can range from $300 to $1000 or more.
Please note that these price ranges are approximate and may have changed since my last update.
