Every time you replace your clutch, you should inspect your flywheel. If it's scored or if there is significant wear in the surface, then you should have it checked and resurfaced. If you have any doubts, replace it with a new one. Scored or burnt flywheels will not create a good mounting surface on which to press the clutch disc, and could very well lead to your clutch slipping later on.
The pressure plate is what holds the clutch disc against the flywheel and transfers power from the engine to the transmission. If the pressure plate is old or failing, the clamping force may not be enough to transfer all of the power from the flywheel to the transmission without having the clutch 'slip.' A worn out clutch disc may also contribute to the slipping of the clutch.
This bearing acts as a guide for the drive shaft of the transmission. Every complete clutch job should include a replacement of this flywheel bearing. Pilot Bearing failure can lead to significant damage to the transmission input shaft.
If your clutch hoses appear swollen or cracked, they may need replacement. Replace your hoses today and keep your car running. Don't take that chance of breaking a clutch hose and being stranded by the side of the road.
