Clutch Cover: The primary structural housing enclosing the pressure plates, friction discs, and release mechanisms, ensuring alignment and protection.
Main Clutch Pressure Plate: Applies clamping force via the Disc Spring to engage the Main Clutch Friction Plate Assembly with the engine flywheel, transmitting power to the transmission input shaft.
Auxiliary Clutch Pressure Plate: Similarly applies force to engage the Auxiliary Clutch Driven Plate Assembly, transmitting power to auxiliary drives (e.g., independent PTO).
Disc Spring (Diaphragm Spring): Provides the primary clamping force for both main and auxiliary clutches. Its deflection allows for clutch disengagement.
Main Clutch Release Lever & Auxiliary Clutch Release Lever: Pivotal levers actuated by the clutch pedal/cable/hydraulics. When pulled, they disengage their respective clutch by overcoming the disc spring force.
Top Rod & Auxiliary Clutch Pull Rod: Linkages transmitting force from the operator controls to the release levers.
Main Release Lever Spring & Auxiliary Release Lever Spring: Return springs ensuring the release levers retract fully when clutch pedal pressure is released, allowing re-engagement.
Ball Nut (Dual): Low-friction spherical bearings integrated into the linkage system (likely connecting pull rods to release levers), ensuring smooth, efficient force transfer with minimal wear.
Pin (Multiple) & Long Pin: Hardened pins providing pivotal connection points for release levers, linkage rods, and levers within the housing. Essential for articulation.
Main Clutch Adjusting Screw: Allows precise calibration of the main clutch release lever position or free play, ensuring optimal engagement point and lever travel.
Hexagon Nut & Nut: Fasteners used to secure linkage components (like ball nuts), adjuster screws, and internal parts. Grade 8.8 is implied for critical points.
Washer: Used under nuts and bolt heads to distribute load and prevent damage.
Main Clutch Friction Plate Assembly: The splined friction disc, lined with high-wear material, sandwiched between the flywheel and main pressure plate. Transmits torque when clamped.
Auxiliary Clutch Driven Plate Assembly: The equivalent friction disc for the auxiliary clutch system.
