Clutch and its nodes

Engine Flywheel: The flywheel is bolted to the crankshaft to resist torsion.

Clutch disc (driven disk): is axially miscible and torsion resistant on the gearbox input shaft. Friction linings are riveted on both sides of the steel disc. The outer diameter of the clutch disc in the Focus has different sizes, depending on the engine: 1.4 / 1.6 l Zetec-SE - 210 mm; 1.8 / 2.0 L Zetec-E - 220 mm; 1.8L Endura DI - 228mm.

Clutch pressure plate (automatic clutch): screwed to the flywheel resistant to twisting. Presses the floating clutch disc against the flywheel by means of a Belleville spring.

Release bearing (in all Focus models integrated directly into the clutch master cylinder). It is located with the possibility of axial displacement on the release shaft. The pressure force generated by the clutch pedal is transferred to the disc spring of the clutch pressure plate. Due to this, the pressure plate is unloaded - the driven disc loses clamping pressure to the engine flywheel.

Regulating automation: in all Focus models, the hydraulically actuated clutch automatically adjusts the prescribed clutch pedal play. Cumbersome installation work is eliminated. If the clutch in your Focus is slipping, then you should assume that it is due to be replaced or, maybe, the pressure valve at the clutch hydraulic inlet is jammed.
