Removal: –  Unplug connector -1-. –  Remove bolts -arrows-. l  Gas hoses remain connected to gas rail. –  Release the wiring from the fixing of the carrier cover and from the gas hoses. –  Place the gas distribution rail „Gas rail“ aside without removing the cables and hoses.

–  Remove bolts -arrows- and lift the carrier cover upwards and away. –  Remove poly V-belt → Chapter.

–  Loosen pulley securing bolt. Hold belt pulley with counterhold -3415- and -3415/1-. Installation –  Install pulley with new bolt and tighten bolt hand-tight.

–  Turn crankshaft in engine direction of rotation to TDC for No. 1 cylinder:

–  Undo the screw plug in the crankcase. –  Screw threaded locking pin -T10340- into crankcase as far as it will go. –  Tighten threaded locking pin -T10340- to 30 Nm.

Locking pin -T10340- locks crankshaft in direction of engine rotation.   Note t  Note that all contact surfaces from the securing bolt to the crankshaft chain sprocket must be free of oil and grease. t  Always use a new bolt. Tightening torque: 150 Nm + 1/2 turn (180°) further Hold belt pulley with counterhold -3415- and -3415/1-.

–  Unscrew threaded locking pin -T10340- from crankcase. –  Screw plug into the crankcase.

Tightening torque: 30 Nm –  Install poly V-belt → Chapter. Further assembly is basically the reverse of the dismantling sequence.

–  Install the carrier cover and tighten the screws -arrows- to a tightening torque of 8.5 Nm. –  Mount the cables and gas hoses on to the fixing points of the carrier cover.

–  Install the fuel rail „Gas rail“ and tighten the screws -arrows- to a tightening torque of 4 ± 0.4 Nm. –  Insert the connector -1-.
