Install timing belt and tension l  Interlock camshaft with locking pin -MP1-301 (3359)-. l  Lock the crankshaft with the crankshaft arrester -T10050-. l  Interlock tensioning pulley with rig tool -T10265- and in the right end position with fixing nut.   Note t  Adjusting work on the timing belt must only be performed on a cold engine, as the position of the pointer at the tensioning element is temperature dependent.

t  Pay attention to correct fitting of the tensioning pulley in the rear toothed belt guard -arrow-.

–  Turn camshaft sprocket in the slots clockwise in -direction of arrow- as far as the stop. –  Fit timing belt onto crankshaft timing belt sprocket, tensioning pulley, camshaft sprocket and onto the coolant pump. –  Install guide pulley → Chapter (Pos. 12). –  Remove rig tool -T10265- from the tensioning pulley and loosen its fixing nut.

–  Turn the eccentric of the tensioning pulley with offset screwdriver -T10264- clockwise -arrow- in such a way until the pointer -2- stands in the centre of the base plate in the gap.   Note Ensure that the fixing nut of the tensioning pulley does not turn. –  Hold the tensioning pulley in this position and tighten the fixing nut -1- of the tensioning pulley to 20 Nm + torque a further + 45° (1/8 turn).   Note When tightening the fixing nut, the pointer -arrow- turns max. 5 mm to the right from the gap of the base plate. This position must not be corrected, because the toothed belt settles when running-in.

–  Position the counterholder -T10172- with bolt -T10172/4- at camshaft sprocket as shown and keep the camshaft sprocket under tension in -direction of arrow-. –  Tighten fixing screws -1- of camshaft sprocket to 20 Nm + torque a further 45° (1/8 turn). –  Remove rig pin -MP1-301 (3359)- and crankshaft arrester -T10050-. Test timing –  Turn the crankshaft 2 turns in the direction of running of the engine until the crankshaft is positioned shortly before TDC for cylinder 1.

–  Interlock during this motion the hub in the direction of running of the engine with locking pin -MP1-301 (3359)-. –  Check whether:

t  the crankshaft can be interlocked with the crankshaft arrester -T10050-; t  The pointer of tensioning pulley stands in the centre or max. 5 mm to the right from the gap of the base plate. If the crankshaft cannot be arrested:

–  Release the screws -arrows- of the camshaft sprocket.

–  Rotate the crankshaft in direction of rotation of engine until the crankshaft can be arrested with the crankshaft arrester -T10050-.   Note If the crankshaft can be turned behind the TDC for cylinder 1, turn crankshaft back slightly and once again set to the TDC for cylinder 1 by turning in direction of rotation of engine. –  Tighten fixing screws of camshaft sprocket to 20 Nm + torque a further 45° (1/8 turn). –  Remove the locking pin -MP1-301 (3359)- and the crankshaft arrester -T10050-. –  Turn crankshaft 2 turns in the direction of running of the engine until the crankshaft is again on TDC. –  Repeat timing test → Anchor. –  Further installation occurs in reverse order for removal, while paying attention to the following. Tightening torque of engine mount → Chapter.
