R 34402), manufacturer Retech s.r.o. t  Cleaning agent and grease remover e.g. -D 000 401 04- Removing –  Remove engine cover with air filter → Chapter. –  Unscrew pressure control valve (PCV valve).

–  Disconnect the vent line -1-. To do so press the securing ring.

–  Separate the ventilation hose at the activated charcoal filter -2- and at the reservoir of the windscreen washer system -arrow- and expose. –  Remove activated charcoal filter and bracket. –  Remove the expansion reservoir and lay it to one side.    Coolant hoses remain connected. –  Remove noise insulation → Body Work → Rep. Gr.50. –  Remove the front right wheelhouse liner → Body Work → Rep. Gr.66. –  Remove V-ribbed belt → Chapter. –  Remove belt pulley from the coolant pump → Chapter. –  Remove AC compressor with the refrigerant lines connected from the bracket → Chapter.    To this end comply with the instructions for the assembly work on the air conditioning system → Chapter. –  Remove the holder for tensioning element and AC compressor.

–  Remove AC generator and guide pulley -2- → Electrical System → Rep. Gr.27.

–  Remove crankshaft belt pulley.    Counterhold crankshaft belt pulley with counterholder -T30004 - and bolt -T30004/1-.   Caution Risk of engine damage. In order to avoid that the chain sprocket on the crankshaft slides out of the driver, the crankshaft must not be turned when the V-ribbed belt pulley is released. –  Removing the oil pan → Chapter.

–  Fit supporting device -T30099-. –  Hang the hook of the spindle on the lifiting eye. –  Pre-tension the engine.

–  Release screws -1 ... 6- and remove engine mounting.

–  Release the Allen screws of the control unit and the screws marked with the -arrows-. –  Place a catch pan under the engine. –  Remove timing case. To do so if necessary slightly raise engine.   Note Please observe that the bushing for the crankshaft remains in the timing case. –  Drive gasket ring for crankshaft out of the timing case. Install Condition l  Timing o.k.   WARNING Wear protective gloves when working with sealant and grease remover! –  Remove residual sealant on the sealing surfaces with chemical sealant remover. –  Degrease the sealing surfaces.   Note Please observe that the contact surface on the crankshaft chain sprocket for the diamond coated washer to be installed at a later stage is free of oil and grease.

–  Insert new gasket rings -arrows- onto the inside of the timing case.   Note t  Furthermore, the timing case is sealed to the engine with a seal and additionally with the sealant -D 176 501 A1-.

t  The sealant -D 176 501 A1- should prevent leaks between the timing case and the joints -1- and -2-. t  The sealant points must have a diameter of 10 mm and must be approx. 1 mm thick. t  Only apply the sealant immediately before installing the timing case. –  Apply the sealant -D 176 501 A1- onto the joints of the camshaft housing/cylinder head -1- and the cylinder head/cylinder block -2-. –  Carefully place the new gasket onto the dowel pins. –  For better guidance, screw two stud bolts M6x80 into the camshaft housing and the cylinder block.   Note First of all, push the diamond coated washer (inner diameter 23 mm) from the repair set up to the stop onto the crankshaft journal → Chapter. –  Position the oil pan for better guidance without silicone sealant with 4 screws. –  Position timing case onto the studs and dowel pins and press onto the cylinder block.    Make sure that the timing case does not tilt. –  Tighten diagonally and evenly the fixing screws of the timing case.    Tightening torque for M6 screws: 10°Nm    Tightening torque for M10 screws: 50 Nm –  Install engine mount → Chapter. –  Installing the oil pan → Chapter. –  Install new parts for fastening the crankshaft belt pulley → Chapter. Further installation occurs in a similar way in reverse order to removal.
