Clutch: Description and Operation
Movements of the clutch pedal are transferred to the clutch via a servo system, making it easy to use and helping to prevent engine noise and vibration reaching the passenger compartment.
The clutch hub (1) is chromium-plated and the input shaft (2) phosphatized, minimising friction and eliminating the need to lubricate these components.
As the transmission shaft is of a single piece and journalled in the transmission endplates at either end, there is no support bearing on the flywheel. This makes removing and installing the transmission easier.
The throwout (release) bearing (3) sleeve is plastic and requires no lubrication. This means the entire system -from the clutch pedal to the throwout (release) bearing - is maintenance-free.
The clutch pedal is spring-assisted (4) to make gear changing easier.
- When the pedal is at the top of its travel, the spring tries to expand, pushing the pedal upwards.
- When the pedal is pushed down, and clutch resistance is low, this initially compresses the spring until it reaches its flip over point. The spring then expands and turns upwards and helps push the pedal down, helping make the clutch action light and easy.
The clutch pedal does not need any lubrication. All pedal system components are of the low-friction type. The hydraulic clutch transmission system does not need any preventive maintenance.
