What should be lubricated when replacing a clutch assembly?

When replacing a clutch assembly, it is important to ensure that all components that require lubrication are properly serviced to maintain performance and longevity. The correct choice, which encompasses all necessary lubrication points, underscores the importance of addressing each specific area.

Lubricating the pilot bearing is essential as it allows the transmission input shaft to smoothly rotate within the bearing, reducing friction and wear. This is crucial for the engagement and disengagement of the clutch.

The disc splines should also be lubricated, as they facilitate the connection between the clutch disc and the transmission shaft. Proper lubrication here helps to prevent binding and ensures smooth operation of the clutch during shifting.

Pivot bushings, located in the clutch linkage setup, also benefit from lubrication. They play a critical role in the activation of the clutch, and keeping them well-lubricated reduces wear and enhances responsiveness.

The best practice is to ensure that all of these components are appropriately lubricated when replacing a clutch assembly to guarantee everything works harmoniously and efficiently. Therefore, the most comprehensive answer incorporates all required lubrication tasks, rather than just one component.
