Assembly instructions for inserting
the clutch slave cylinder
Move clutch slave cylinder to installation
position and then fix/centre it at the lower
fastening point using a drift punch (A)
measuring 5 x 120 x 10 mm.
3. Fit clutch line on clutch slave cylinder
(do not tighten it yet).
Fit holder with clip on the transmission side
cover (tightening torque of the two screws:
25 Nm (19 ftlb.)).
Clip clutch line into the holder and tighten
the line.
Align clutch slave cylinder -with the drift
punch (A) in place -so that the upper
fastening screw No.3 can be fitted.
4. Bleed hydraulic system of the clutch
(Rep. Gr. 30/ Servo No. 30 01 07).
After fitting the upper fastening screw
No.3, remove the drift punch (A) and
screw in the lower fastening screw.
Important notes:
The clutch hydraulics must always be filled or
bled using a pressure filling and bleeding device.
Furthermore, the bleeder valve must be opened
sufficiently and the gauge pressure must be
approx. 1.5 bar.
Tighten upper and lower fastening
screws (23 Nm (17 ftlb.)).
Before the system is filled or bled, the clutch
pedal must be in the "Pedal fully depressed"
position.
Important: As there is no system pressure,
servo kinematic effects will cause the clutch
pedal to move forward abruptly. In order to
avoid damage, the pedal must be guided
manually.
Bleed the system until no more bubbles appear
at the bleeder valve (use a collecting bottle with
transparent hose).
If the system was open previously I the minimum
filling or bleeding time must be 30 seconds.

5. Check operation of the clutch.
Repeat the bleeding process if the clutch
does not operate (disengage) correctly.
6. Install rear axle cross member.
Tightening torque of the two screws
65 Nm (48 ftlb.).
