Install   Note t  The sealing flange with PTFE gasket ring is provided with sealing lip supporting ring. This supporting ring is intended as an assembly sleeve and must not be removed before installing. t  Do not separate or turn the sealing flange and rotor after removing them from the spare part package. t  The rotor is given its fitting location by fixing the assembly tool -T10134- to the positioning pin. t  The sealing flange and gasket ring form one unit and must be replaced together with the rotor. t  The assembly tool -T10134- is given its fitting location to the crankshaft by means of a guide bolt, which is guided into a hole of the crankshaft.

Assembly tool -T10134- A - Hexagon nut B - Clamping surface C - Assembly cup D - Allan screw E - Guide bolts (with red handle - for fuel engine) F - Positioning pin G - Guide bolts (with black handle - for diesel engine) A - Mounting sealing flange with rotor on the assembly tool -T10134-

–  Screw the hexagon nut -A- right up to the clamping surface -B- and grip the assembly tool -T10134- on the clamping surface -B- of the threaded spindle in a vice.

–  Remove the securing clip -arrow- from the new sealing flange.   Note Do not remove or turn the rotor from the sealing flange.

–  Lay the front side of the sealing flange on a clean and level surface. –  Press down sealing lips supporting ring -A- in -direction of the arrow-, until it rests on the level surface.   Note The top edge of the rotor and the front edge of the sealing flange must be flush. l  The locating hole -B- on the rotor -C- must be flush with the marking -A- on the sealing flange.

–  Lay the sealing flange with the front side on the assembly tool -T10134- in such a way that the positioning pin -A- engages into the hole -B- of the rotor.   Note Make sure the sealing flange lies flat on the assembly tool.

–  When tightening the knurled screws -A- press the sealing lip supporting ring -B- on the surface of the assembly tool in such a way that the positioning pin cannot slide out of the rotor hole. B - Mount the assembly tool -T10134- on the crankshaft flange l  The crankshaft flange must be free of grease and oil l  Crankshaft is at TDC for cylinder 1 –  Unscrew hexagon nut up to the end of the threaded spindle.

–  Screw assembly tool -T10134- with Allan screws -A- up to the stop onto the crankshaft flange.

–  Screw in two M6x35 mm screws -A- by about 3 turns for sealing flange guide into the cylinder block.

–  Move the assembly cup -C- by hand in the -direction of the arrow- until the rotor -B- rests on the crankshaft flange -A-. Subsequently insert the guide bolt with red ball -F- fully into the threaded bore of the crankshaft. If the guide bolt is correctly pushed in, then the handle has a distance of approx. 10 mm from the assembly cup -C-. This gives the rotor its final fitting location. C - Pressing the rotor onto the crankshaft flange –  Screw in hexagon nut by hand onto the threaded spindle until it rests against the assembly cup.

–  Tighten the hexagon nut of the assembly tool using a torque wrench with adapter.    Tightening torque: 35 Nm.   Note After tightening the nut to 35 mm there must still be a narrow air gap between the cylinder block and the sealing flange. D - Inspecting the fitting position of the rotor on the crankshaft

–  Unscrew hexagon nut -E- up to the end of the threaded spindle. –  Unscrew two M6x35 mm screws -A- from the cylinder block. –  Release three knurled screws -B- from the sealing flange. –  Unscrew two Allan screws and remove assembly tool -T10134-. –  Remove sealing lips supporting ring.

The fitting position of the rotor on the crankshaft is accurate if there is a distance -a- = 0.5 mm between the crankshaft flange -A- and the rotor -B-.

–  Position the steel striaghtedge onto the crankshaft flange. –  Measure the distance between the steel straightedge and the rotor with a feeler gauge. If the measured distance is less than 0.5 mm: –  Press down rotor → Anchor. If the dimension is correct: –  Tighten the new fixing screws of the sealing alternately crosswise.    Tightening torque: 10 Nm.

–  Install engine speed sender -arrow-.    Tightening torque: 5 Nm. –  Installing the oil pan → Chapter. –  Installing intermediate plate. –  Install flywheel with new screws. E - Pressing down the rotor

–  Screw assembly tool -T10134- with Allan screws up to the stop onto the crankshaft flange. –  Screw in three knurled screws -A- into the flange. –  Subsequently insert the guide bolt with red ball -E- fully into the threaded bore of the crankshaft. If the guide bolt is correctly slipped on, then the handle has a distance of approx. 10 mm from the assembly cup -B-.

–  Tighten the hexagon nut of the assembly tool using a torque wrench with adapter.    Tightening torque: 40 Nm. –  Again inspect the fitting position of the rotor on the crankshaft → Anchor. If the dimension -a- is again too small: –  Tighten the hexagon nut of the assembly tool to 45 Nm. –  Again inspect the fitting position of the rotor on the crankshaft → Anchor.
