Role of Part 3968254 Clutch Friction Disc in Engine Systems

The part 3968254 Clutch Friction Disc is a component in the operation of the clutch system within engine systems. It is specifically designed to interface between the pressure plate and the flywheel, facilitating the transfer of power from the engine to the transmission.

When the driver engages the clutch pedal, the pressure plate is moved away from the friction disc, allowing the disc to spin freely. This disengagement permits the driver to change gears without interrupting the engine’s operation. Upon releasing the clutch pedal, the pressure plate compresses the friction disc against the flywheel, re-establishing the power flow.

The friction disc is composed of multiple layers, including friction material and steel plates, which are essential for withstanding the high temperatures and pressures generated during operation. The friction material ensures a smooth engagement and disengagement, minimizing wear on other components.

In rear-wheel drive systems, the clutch friction disc plays a significant role in managing the power distribution to the rear wheels. It ensures that the power transfer is efficient and consistent, contributing to the overall performance and durability of the drivetrain.

The integration of the 3968254 Clutch Friction Disc within the clutch assembly is designed to enhance the driving experience by providing precise control over power transmission, ensuring smooth gear changes, and maintaining the integrity of the engine and transmission systems ⁴.
