2. Clutch Group II – 37
The clutch system connects the engine to the transmission, allowing seamless gear changes.
- Clutch Pressure Spring: Ensures the clutch plate engages and disengages smoothly.
- Friction Disk: Transfers torque from the engine to the transmission.
- Flywheel: Balances engine rotation and provides a surface for clutch engagement.
- Clutch Master Cylinder: Transmits hydraulic pressure to engage the clutch.
- Clutch Slave Cylinder: Works in tandem with the master cylinder to disengage the clutch.
3. Transmission Group II – 43
The transmission manages the power flow from the engine to the wheels.
- Gearing: Facilitates speed and torque adjustments.
- Gear Change System: Enables smooth gear transitions.
- Oil System: Lubricates the moving parts within the transmission.
4. Propeller Shaft and Universal Joint Group II – 53
These components transfer power from the transmission to the rear axle.
- Universal Joint: Allows flexibility in power transfer while the vehicle moves.
- Propeller Shaft: Transmits torque to the differential.
- Flexible Coupling: Absorbs vibration and reduces stress on the drivetrain.
5. Differential Group II – 55
The differential enables the wheels to rotate at different speeds during turns.
- Angular Contact Bearings: Provide stability and precision to the gears.
- Gear Backlash: Ensures smooth gear operation without binding.
- Differential Mounting: Secures the differential to the chassis.
- Rear Axle Mounting: Connects the axle to the suspension system.
- Axle Housing: Protects internal components from external damage.
6. Rear Axle Group II – 59
Ensures efficient power transfer to the wheels.
- Chain and Chain Tensioner: Maintain proper tension for smooth power delivery.
- Rear Hub Shaft: Connects the wheels to the drivetrain.
- Breather: Prevents pressure build-up within the axle.
7. Front Suspension Group II – 61
Critical for ride comfort and handling.
- Upper and Lower Control Arms: Guide wheel movement.
- Torsion Bar: Absorbs shocks and vibrations.
- Height Adjusting Bolt: Allows ride height adjustment.
- Front Damper: Reduces oscillation for a smooth ride.
8. Rear Suspension Group II – 63
Balances ride quality and vehicle stability.
- Rear Damper: Mitigates rear wheel oscillations for better control.
9. Steering System Group II – 65
Provides precise control over vehicle direction.
- Rubber Coupling: Dampens vibrations in the steering column.
- Rack and Pinion: Converts rotational motion to linear movement.
- Tie Rods and Ends: Connect the steering rack to the wheels.
- Steering Wheel Lock: Adds security when the vehicle is stationary.
10. Braking System Group II – 69
Ensures safe stopping power.
- Master and Wheel Cylinders: Generate and transmit hydraulic pressure.
- Brake Drums and Shoes: Create friction to slow down the wheels.
- Parking Brake: Keeps the vehicle stationary.
- Equalizer Arm: Balances braking force across wheels.
11. Body Group II – 73
The body ensures safety and aerodynamics.
- Styling: Defines the vehicle’s appearance.
- Structure: Provides rigidity and crash protection.
12. Frame Group II – 77
The backbone of the vehicle, offering structural support.
13. Top Group II – 79
Covers convertible roof systems for added functionality.
14. Interior Furnishing Group II – 81
Focuses on comfort and aesthetics.
- Seats: Provide ergonomic support for passengers.
- Instrument Panel: Displays essential vehicle information.
15. Electrical System Group II – 83
Manages power distribution and controls.
- Ignition and Starting System: Initiates engine operation.
- Charging System: Powers the battery and accessories.
- Fuel Pump and Safety Equipment: Ensure reliable fuel delivery and passenger protection.
