6. DRAINING AND FILLING

6.1 DRAINING AND FILLING CLUTCH SYSTEM

Hydraulic fluid is toxic and can

therefore have a damaging effect on

your health. Any direct or indirect

physical contact should therefore be

avoided. As hydraulic fluid is also

corrosive it may damage the

paintwork of the vehicle. Any

contact between hydraulic fluid and

paintwork should therefore be

avoided.

Always use new and clean hydraulic

fluid which has been kept in a sealed

container that meets the

specifications. Hydraulic fluid which

has absorbed water (from the

ambient air) may have an adverse

effect on the operation of the clutch

system. Avoid any contact with

mineral oil. Even one drop of mineral

oil in the system will damage the

seals.

Draining clutch system
1.

Place a container beneath the clutch servo.

2.

Disconnect the supply pipe from the clutch

servo and drain the oil from the reservoir by

moving the pedal up and down.

3.

Reinstall the supply pipe.

Filling clutch system
1.

Fill the reservoir with the specified fluid and

bleed the system.

6.2 BLEEDING CLUTCH SYSTEM

Hydraulic fluid is toxic and can

therefore have a damaging effect on

your health. Any direct or indirect

physical contact should therefore be

avoided. As hydraulic fluid is also

corrosive it may damage the

paintwork of the vehicle. Any

contact between hydraulic fluid and

paintwork should therefore be

avoided.

Always use new and clean hydraulic

fluid which has been kept in a sealed

container that meets the

specifications. Hydraulic fluid which

has absorbed water (from the

ambient air) may have an adverse

effect on the operation of the clutch

system. Avoid any contact with

mineral oil. Even one drop of mineral

oil in the system will damage the

seals.

Bleeding the clutch system using the "servo"
bleed tank
1.

Connect the "servo" bleed tank to the

reservoir.

Note:

Filling too quickly causes foaming, which makes

bleeding virtually impossible.

2.

Fill the system via the "servo" bleed tank.

3.

Connect a transparent pipe to the clutch

servo's bleed nipple. Ensure that the

hydraulic fluid is collected.

4.

Open the bleed nipple two full turns.

5.

As soon as no more air bubbles escape from

the transparent pipe, the bleed nipple can be

closed again.

6.

Check the fluid level. See "Inspection and

adjustment".
