The Harley-Davidson 79-2105 Starter Jackshaft Kit is an essential replacement component for your Harley-Davidson motorcycle. This kit is designed for the Sportster XL 1200N and XL 1200X models, providing a crucial upgrade or repair solution for the jackshaft starter system.
The jackshaft kit consists of carefully engineered components, ensuring a perfect fit and reliable operation. The kit includes a starterdrive gear, starter drive gear splines, new drive gear spline retainer bolts, and necessary seals. These replacement parts are meticulously manufactured to meet Harley-Davidson's rigorous quality standards.
The starterdrive gear, an essential part of your motorcycle's starting system, is designed to connect the ignition system to the engine's crankshaft. This gear experiences significant wear due to continuous engagement with the starter motor, making it prone to failure over extended use. By replacing it with the 79-2105 Starter Jackshaft Kit, you'll ensure that your bike's starting system operates smoothly, efficiently, and effectively.
The kit also includes starter drive gear splines, which connect the starterdrive gear to the engine's flywheel. These splines often wear down during the bike's lifetime, leading to transmission issues. Replacing them with the new ones provided in the kit maintains the necessary spline engagement and keeps the transmission functioning correctly.
Additionally, the 79-2105 Starter Jackshaft Kit offers new drive gear spline retainer bolts. These bolts secure the starterdrive gear to the engine and are prone to loosening or failure due to vibration from the engine. Upgrading to new retainer bolts with the kit guarantees a solid connection between the starterdrive gear and the engine.
Seals are also included in the kit to ensure a proper seal between the transmission and the engine housing. Over time, the seals can degrade or leak, causing detrimental damage to the engine and other components. Replacing the seals in the 79-2105 Starter Jackshaft Kit keeps the engine compartment sealed, protecting your motorcycle from potential issues.
In summary, the Harley-Davidson 79-2105 Starter Jackshaft Kit is a comprehensive solution for maintaining the health and functionality of your Sportster XL 1200N or XL 1200X motorcycle's starting system. By upgrading the important parts included in the kit, you'll secure reliable starting performance and extend the life of your Harley-Davidson.
