Drive Shaft: The drive shaft connects the output shaft of the transmission to the final drive motor.
It transfers rotational force from the engine to the motor, which then drives the rear wheel. If the drive shaft becomes damaged or worn, it can result in poor power transmission and affect the overall performance of the motorcycle. Replacing the drive shaft with a new one is essential to ensure proper power transfer.
Sprockets: The final drive system consists of two sprockets: the front sprocket (attached to the output shaft) and the rear sprocket (mounted on the wheel hub). These sprockets are connected by a chain, and together, they determine the gear ratio and affect the motorcycle's acceleration and top speed. If the sprockets become worn, damaged, or have missing teeth, replacing them is necessary to maintain optimal power transfer and overall performance.
Chain: The chain in the final drive system is responsible for transmitting power from the front sprocket to the rear sprocket. It is exposed to high levels of tension, stress, and contaminants, which can cause stretching, rusting, or damage over time. Replacing the chain when it becomes worn or damaged is crucial to ensure smooth power transfer and prevent potential chain failure while riding.
Chain Tensioner: The chain tensioner maintains proper tension in the chain to prevent slack or excessive tightness. It is usually a spring-loaded mechanism that adjusts the chain's tension automatically as it wears. If the chain tensioner becomes faulty or worn out, it may result in improper chain tension, affecting the motorcycle's performance and increasing the risk of chain-related issues. Replacing the chain tensioner ensures proper chain tension and enhances overall drivetrain reliability.
Seals and Bearings: The final drive motor may have various seals and bearings that contribute to its smooth operation and prevent lubricant leakage.
These include output shaft seals, wheel hub bearings, and other seals within the final drive assembly. Over time, these seals and bearings can wear out or get damaged, resulting in oil leaks, increased friction, and reduced efficiency. Replacing worn or faulty seals and bearings is essential to maintain proper lubrication and ensure optimal performance of the final drive system.
Gaskets: Gaskets provide a tight seal between different components of the final drive motor, preventing oil leaks and maintaining proper lubrication. When replacing parts within the final drive assembly, it is often necessary to replace gaskets as well to ensure a proper seal and prevent any oil leakage that could damage the motor or affect its performance.
