Harley-Davidson 21900101 107 128 4.310 M8 Big Kit IV 16800210 - Transmission Drive and Clutch Assembly for Harley-Davidson Motorcycles

The Harley-Davidson 21900101 107 128 4.310 M8 Big Kit IV 16800210 is a transmission drive and clutch assembly designed specifically for Harley-Davidson motorcycles. This high-quality kit is an essential component for maintaining the performance and reliability of your Harley-Davidson bike.

This Big Kit IV includes several important parts that are vital for smooth operation of your motorcycle's power transmission system. The primary components include the transmission shaft, clutch housing, clutch basket, clutch shoes, clutch springs, and the clutch release bearing. Each part is engineered to exacting specifications to ensure a perfect fit and optimal function with Harley-Davidson motorcycles.

The transmission shaft is a robust part that facilitates the transfer of power from the engine to the transmission. Harley-Davidson uses precision-machined, heat-treated steel to create this component, ensuring its durability and longevity.

The clutch housing is the component that contains the clutch components and forms part of the primary drive system. This housing is designed to accommodate various clutch sizes and applications, making it a versatile upgrade option for many Harley-Davidson models.

The clutch basket is where the clutch shoes slide when the clutch is engaged, allowing the driven sprocket to connect to the transmission output shaft. Harley-Davidson has manufactured this clutch basket from high-quality steel that can withstand the stresses and wear of continuous use.

The clutch shoes are a crucial part of the engagement system. They slide along the clutch basket when the clutch is operated, creating hydraulic pressure that forces the clutch plates to engage and disengage. These clutch shoes are designed with a durable, heat-resistant composites material, ensuring long life and consistent performance.

The clutch springs play a vital role in the engagement and disengagement of the clutch plates. They are manufactured using heavy-duty, high-tension steel wire and are engineered to provide the correct amount of force for proper clutch operation.

Finally, the clutch release bearing is a critical component that enables the lever arm to engage the release cam, which disengages the clutch plates. This bearing allows for smooth and efficient engagement and disengagement of the clutch, contributing to a positive riding experience.

In summary, the Harley-Davidson 21900101 107 128 4.310 M8 Big Kit IV 16800210 is a comprehensive and effective solution for maintaining the performance and reliability of your Harley-Davidson motorcycle's power transmission and clutch system. With each component meticulously designed and manufactured to Harley-Davidson's rigorous standards, this kit ensures years of dependable service and enjoyment for your motorcycle.
