Starter clutch

Types of starter clutches

A starter clutch is often referred to as a starter motor, and it is located between the flywheel and the transmission. It is the part of the starter that gets the starter motor to crank when a person turns the ignition key. Without a working starter motor, no one will be able to start their car.

Engaged and disengaged starter clutches are the two main types of starter clutches.

• Engaged starter clutch

  This is one of the most commonly used starter clutches in motorcycles. When the rider pulls the clutch lever, the clutch plates inside the engine sprocket cover separate. This action breaks the connection between the engine and the wheels, allowing the engine to run freely without dragging on the wheels. When the clutch lever is released, the clutch plates come together, linking the engine to the wheels, enabling the bike to move forward or backward.

• Disengaged starter clutch

  This type of starter clutch works the opposite way. When the rider pulls the clutch lever, the plates do not separate. Instead, they slightly adjust their position, and the connection between the engine and the transmission is minimized but not entirely broken. This allows the engine to continue driving the bike with some resistance, enabling the rider to shift gears without causing the bike to stall.

However, not all motorcycles have the disengaged starter clutch. Most modern bikes and some newer manual transmission vehicles use this system. It provides a balance between completely separating the engine from the wheels and maintaining some connection to allow for smoother gear changes.

Specification and Maintenance of Starter Clutch

When looking for a starter clutch for sale, buyers must consider the specifications of the product to ensure it meets the needs of the target market. Here are some of the key specifications to look out for:

• Starter Motor Compatibility

  The compatibility between the starter motor and the flywheel is crucial for the proper function of the engine. This is because the starter motor is responsible for cranking the engine. Therefore, ensure that the specifications of the starter motor match those of the flywheel for optimal performance.

• Material

  The starter clutch is made from steel, aluminum, or other composite materials. Each of these materials has its advantages. For instance, steel is strong and durable, making it ideal for heavy-duty applications. Aluminum, on the other hand, is lightweight and resistant to corrosion.

• Gear Ratio

  The gear ratio is the relationship between the number of teeth on the starter clutch and the number of teeth on the flywheel. The gear ratio affects torque and the speed of the starter motor. A higher gear ratio means more torque but slower speed.

• Size

  The size of the starter clutches varies depending on the engine size and its specifications. A smaller starter clutch is suitable for small engines. On the other hand, larger starter clutches are ideal for use in large engines.

• Teeth Count

  The number of teeth on the starter clutch also varies depending on the engine design. Most starter clutches have between 9 and 14 teeth. The teeth count impacts the engagement and disengagement of the starter clutch.

• Load Capacity

  The load capacity of the starter clutch is the maximum load it can handle without failure. This specification is important because exceeding the load capacity can lead to starter clutch damage. Different starter clutches have different load capacities. For instance, some starter clutches can handle loads of up to 2000 pounds.

• Rotational Speed

  The rotational speed of the starter clutch is the speed at which it spins during starting. The rotational speed is important because it affects the starting performance. A high rotational speed means better starting performance. The rotational speed of the starter clutch is measured in revolutions per minute (RPM). Most starter clutches have an RPM of 2000 to 3000.

• Quality

  Starter clutches are available in a wide range of qualities. Premium quality starter clutches are more expensive but offer better performance and durability. Quality is an important consideration when looking for a starter clutch to buy.

Once a suitable starter clutch is purchased, it is important to ensure that it serves its purpose for a long time. Here are some of the maintenance tips:

• Proper Installation: Follow the manufacturer's instructions to install the starter clutch properly. Also, ensure that all the components are fitted tightly to avoid unnecessary wear and tear.
• Regular Inspection: Regularly inspect the starter clutch for signs of wear and damage. Also, check for oil and grease leaks and fix them immediately.
• Cleaning: Keep the starter clutch clean by removing dirt and debris using a soft cloth. Avoid using harsh chemicals that may damage the starter clutch.
• Lubrication: Lubricate the starter clutch according to the manufacturer's instructions. Use the recommended lubricant for optimal performance.
• Avoid Overstarting: Do not crank the engine excessively. Over cranking can put a lot of stress on the starter clutch, leading to damage.
• Replace Worn Parts: Replace worn or damaged components promptly to avoid further damage to the starter clutch.
• Professional Maintenance: If unsure about maintaining or repairing the starter clutch, seek professional assistance.

How to choose a starter clutch

There are several factors to consider when choosing the right starter clutches, such as:
