Clutch Hydraulic System: Service and Repair

Removing and installing the accumulator





Removal
1. Raise vehicle on lifting platform.
2. Actuate the clutch pedal at least 25 times with the engine switched off so that the system is depressurized.





3. Undo the screws -arrows- and remove the front cross member.
4. Remove clips from the coolant lines.
5. Remove bracket for the coolant lines.

Note:
^ Take care when handling Pentosin! Wear protective glasses, gloves and protective clothing!
^ If coolant hoses come into contact with Pentosin, thoroughly clean them with water IMMEDIATELY!





6. Remove the accumulator -arrow-. Use an open-ended wrench to undo the accumulator. Then turn the accumulator further (remove) with an oil filter strap.

Installation
1. Set the accumulator in place and twist the accumulator into position using an oil filter strap. Use an open-ended wrench to tighten the accumulator (tightening torque 30 Nm 22.2 ft. lbs.).
2. Install the bracket for the water hoses and clip the hoses into place. Align the hoses.
3. Install the front cross member. Tightening torque of the fastening screws: 65 Nm (48.1 ft. lbs.).

Caution:
Danger of material damage if the wrong fluid is used for the clutch hydraulic system!

Danger of damage to property if too much Pentosin CHF 11 S is filled or if it comes in contact with the coolant hoses when topping up or filling in!

^ Fill Pentosin CHF 11 S only into the supply tanks!
^ To prevent overfilling and, therefore, overflowing, check the specifications in the clutch, fluid levels description and observe them without fail!
^ Multiple steering operations (maneuvering) and/or actuating the clutch with the engine switched off change the fluid level in the engine-compartment reservoir! Fluid level rises. In this case, the engine must be run for approximately 20 seconds immediately prior to the fluid level check!
^ If coolant hoses come into contact with Pentosin, thoroughly clean them with water IMMEDIATELY!
^ Replace visibly swollen coolant hoses!

4. Top up hydraulic fluid Pentosin CHF 11 S in the expansion tank in the engine compartment.
