Clutch Controls - Overview

OVERVIEW

The clutch is a conventional type, with a single stage damped driven plate and a spring clutch cover assembly which is hydraulically actuated from the clutch pedal.

Operation of the clutch pedal produces hydraulic pressure in the master cylinder which is passed via pipes to the slave cylinder which disengages the clutch. The clutch shares a common fluid reservoir with the brake system and is connected via a low pressure pipe from the brake master cylinder.

Clutch Controls - System Operation and Component Description

System Operation

OPERATION

Pressing the clutch pedal operates the clutch master cylinder which pressurizes the hydraulic fluid. The fluid pressure is transferred via a high pressure pipe from the master cylinder to the slave cylinder. The fluid pressure operates the slave cylinder, which in turn pushes the fingers of the clutch cover, releasing the driven friction plate and disengaging the drive from the engine crankshaft to the transmission.

Component Description

DESCRIPTION

The clutch controls comprise a clutch pedal, a master cylinder, a high pressure pipe and a slave cylinder.

The clutch uses a fluid reservoir shared with the brake system. A low pressure pipe provides hydraulic fluid from the reservoir, via a connection on the brake master cylinder, to the clutch master cylinder. A two piece high pressure pipe is connected from the clutch master cylinder to the slave cylinder. The high pressure pipe has a quick release connection near to a bracket on the transmission which allows the upper pipe to be disconnected from the lower pipe. The lower pipe is connected to the clutch slave cylinder via another quick release connector.

The slave cylinder is located in the transmission housing and is secured with a bolt to the casing. The slave cylinder has an internal bearing which locates over the transmission output shaft, which passes through the center of the slave cylinder.

The lower high pressure pipe passes through a sealed hole in the transmission housing and connects to the slave cylinder with another quick release connector.

A bleed screw is fitted in an adaptor located in the lower high pressure pipe, near the point where the pipe enters the transmission casing. The bleed screw allows the system to be purged of air after replacement or removal of one of the clutch hydraulic components. The adaptor also contains a peak torque limiter. The torque limiter prevents instant clutch engagement if the driver accidentally releases the clutch pedal quickly, preventing damage to the driveline components.

Stop/Start Vehicles

On vehicles with the stop/start system the clutch master cylinder is fitted with a linear clutch sensor. The sensor is hardwired to the CJB (central junction box) and is used to sense the position of the clutch pedal. It is used in conjunction with other sensor outputs to initiate an engine restart, engine stop or engine stall recovery on vehicles with the stop/start system. It is also used in conjunction with the first gear and reverse gear switches to complete clutch plausibility.

Linear Clutch Sensor

Range Rover Evoque. Clutch Controls - Vehicles With: M66 6-Speed Manual Transmission AWD

A magnet inside the clutch master cylinder provides the position indicator for the linear clutch sensor.

The master cylinder and sensor are common on all models. The master cylinder and sensor are supplied as an assembly and cannot be obtained separately.

Removal

NOTES:

The clutch slave cylinder and release bearing are a combined assembly and cannot be serviced separately.

Removal steps in this procedure may contain installation details.

1. Disconnect the battery ground cable.

Refer to: Specifications (414-01 Battery, Mounting and Cables, Specifications).

2. WARNING: Make sure to support the vehicle with axle stands. Raise and support the vehicle.

3. Refer to: Transmission - Vehicles With: M66 6-Speed Manual Transmission AWD (308-03 Manual Transmission/Transaxle, Removal).

Refer to: Transmission - Vehicles With: M66 6-Speed Manual Transmission FWD (308-03 Manual Transmission/Transaxle, Removal).

4. CAUTIONS:

If brake fluid is spilt on the paintwork, the affected area must be immediately washed down with cold water.

Make sure that all openings are sealed. Use new blanking caps.
