t  Hose clamp -3036-, see equivalent → Anchor

t  Extractor -T40001-, see equivalent → Anchor Removing   Note t  Sealing surfaces at bottom of retaining frame and top of cylinder head may not be machined. t  The camshaft bearings are integrated into the cylinder head and retaining frame. Toothed belt must be slackened before removing retaining frame. t  Renew camshaft oil seal and sealing cap if retaining frame has been unfastened. –  Remove the variator → Chapter. –  Remove toothed belt → Chapter.

–  Loosen the sprocket of the cam shaft with the counter holder -3036-.

–  Release the camshaft sprocket with the extractor -T40001-, the claw -T40001/6- and the claw -T40001/7-. –  Separate the rear toothed belt protection from the cylinder head. –  Loosen retaining frame bolts evenly working from outside inwards and remove retaining frame. –  Carefully lift out the camshafts and place them down on a clean surface.

–  Remove old sealant residues from the slot of the upper bridge and from the sealing faces. –  Prevent dirt and sealant remains from entering the cylinder block. Installing   Note t  The contact surfaces must be free from oil and grease. t  Pistons must not be at TDC. t  See that the roller rams rest properly on the valve stem ends. –  Oil the camshaft running surfaces.

–  Insert camshafts carefully in the camshaft bearings of cylinder head. Cams -A- of cylinder 4 must face each other.

–  Apply a uniform and slightly raised sealant grub in the clean slot of the top bridge → Parts catalogue. Distribute sealant evenly on sealing surface.   Note t  The sealant must not be applied too thickly. Remove excess sealant with a cloth that does not fray. t  The assembly and bolting of the top bridge must be carried out without interruption, as the sealant hardens up as soon as the sealing faces are in mutual contact. t  Note the use-by date of the sealant.

–  Set the top bridge such that it reaches the exhaust return valve -N18--arrow-. –  Tighten the screws from inside outwards lightly and in several steps.

–  Then tighten bolts in the sequence indicated to 8 Nm. –  Fit cover → Item with pressure tool -3334- 1... approx. 2 mm –  Fit the camshaft seal → Chapter. –  Install toothed belt cover (rear). –  Fit the spring buckle in the camshaft.

–  Mounting the cam shaft sprocket. To tighten the bolt, immobilise the camshaft sprocket with the counterhold -3036-. Tightening torque: 65 Nm.   Note t  When turning the camshaft, the pistons must not be at TDC. Otherwise there is a risk of damage to valves and pistons. t  Ensure correct seating of the centring spring. –  Install toothed belt → Chapter. –  Fitting the variator → Chapter. –  Install cylinder head cover → Chapter. –  Assemble the lock carrier with attachments → Bodywork - Exterior assembly work ; Rep. gr.50.

–  The torque reaction support must set itself on its rubber stop by means of its self weight, then tighten the nuts -arrows-. –  Fit the front bumper cover → Exterior body installation work; Rep. gr.63. –  Check headlight adjustment → Booklet301. Installation is done in the reverse order. Tightening torques Valve control: assembly overview → Chapter. Assembly overview - cylinder head → Chapter.
