t  Adjustment tool -T40098-, please see Correspondence → Anchor

t  counterhold -T20208-, see equivalent → Anchor Removing –  Move the lock carrier plate into service position without removing the charged air and coolant hoses → Rep. gr.50. –  Remove timing chain cover (top) → Chapter.   Caution The control valve has a left hand side thread.

–  Remove the control valve using the assembly tool -T10352- or assembly tool -T10352/1- in the -direction of the arrow- depending on the version.

–  Unscrew the bolts -arrows- and remove the subframe.

–  Turn the vibration damper to „TDC“ position -arrow- using counterhold tool -T10355-. l  Notch on vibration damper must align with arrow marking on cover for timing chains (bottom). l  The markings -1- on the camshafts must face upwards.

–  Attach the retaining tool -T20208- and block the camshaft turning. l  The marks of the camshafts should coincide with the marks on the counterhold -T20208-.   Note

t  When necessary, turn the intake camshaft in the -direction of arrow A- using a wrench until the markings on the camshaft and on the support tool -T20208- correspond with each other. t  This figure is used as an instruction, being a requirement that the support tool -T20208- is mounted and that the sprocket in the camshaft is not blocked. –  Remove the lower cover of the distribution chain → Chapter.

–  Press the oil-pump chain tensioner in the -direction of the arrow- and immobilise it with the locking pin -T40011-. –  Remove oil pump chain tensioner -1-. –  Remove oil pump chain.

–  Insert scriber or suitable screwdriver in hole of chain tensioner in direction of -arrow 1- and lift locking element for chain tensioner. –  Press tensioning rail for timing chain in direction of -arrow 2- and lock in place using locking pin -T40011-. –  Detach camshaft timing chain from cylinder head.   Note Inlet camshaft will move in direction of engine rotation.

–  Remove tensioning rail for timing chain -2-. –  Remove guide rail for camshaft timing chain -1-. –  Remove timing chain. Installing l  Tightening torque → Chapter   Note t  The painted links of the distribution chain should be positioned in the marks of the pinions. t  The play of the chain should be between the exhaust camshaft and the crankshaft, to be taken up when the chain tensor is released.

–  Fit the distribution chain over the camshaft pinions observing the marks. –  Fit the distribution chain over the crankshaft observing the mark.

–  Fit tensioning rail for timing chain and tighten bolt -2-.

–  Mount the top guide rail -3-. –  Fit the chain of the oil pump to the crankshaft → Item. –  Remove the clamp -T40011- so that the chain is tensed. –  Extract the counterhold -T20208-.

–  Fit the sub-frame and tighten the bolts -arrows- by hand. –  Tighten the bolts -arrows- of the sub-frame, tightening torques → Chapter. The remaining installation steps are carried out in the reverse sequence. Note the following points: –  Fit the lower cover of the distribution chain → Chapter. –  Install timing chain cover (top) → Chapter. –  Install Poly V-belt tension device → Chapter. –  Install poly V-belt → Chapter. –  Put the lock carrier plate into service position → Rep. gr.50.
