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".
