–  Unhook intermediate plate on sealing flange and on the dowel sleeves -arrows-. –  Put the engine in TDC of cylinder 1 → Chapter. –  Remove sump → Chapter.

–  Remove the engine speed sender -G28-- 1- using the articulated Allen key.

–  Unscrew the attachment bolts -1 … 6- from the sealing flange.   Note The sealing flange and the sender wheel are removed together from the crankshaft by the three M6 x 35 mm bolts.

–  Screw three bolts M6 x 35 mm into the threaded spaces of the sealing flange-arrows-. –  Screw in the 3 bolts M6x35 alternately max. 1/2 turns (180° per bolt) into the sealing flange. –  Remove the sealing flange with sender wheel. Fit the sealing flange with the sender wheel   Note t  The sealing flange with the PTFE seal is fitted with a pressure ring on the sealing lip. This support ring acts as an assembly sleeve and must not be removed before installation. t  Once unwrapped, do not separate the sealing flange and the sender wheel or modify the position. t  The sender wheel finds its position automatically when fitted to the position pin of the centre guide -T10134-. t  The sealing flange and the seal make up one inseparable component and can only be replaced along with the sender wheel. t  The centre guide -T10134- is held in its installation position for the crankshaft by a guide pin which is inserted into a hole on the crankshaft.

Structure of the centre guide -T10134- A -  Tightening flats B -  Conical hexagon bolt C -  Installation bell D -  Locating pin E -  Hexagon socket head bolt F -  Guide pin for diesel engines (black handle) G -  Guide pin for diesel engines (black handle)

A - Fit the sealing ring with sender wheel in the centre guide -T10134-: –  Screw in hexagon nut -B- to just before clamping surface -A- of threaded spindle.

–  Fix the centre guide -T10134- holding it in place in a bench vice, to the threaded spindle surface -B-. –  Press down on the installation bell -C-, so that it rests -arrow- on the hexagonal bolt -B-.   Note Inner part of assembly device and assembly housing must align (be level) with each other.

–  Unscrew the attachment clip -arrow- from the new sealing flange.   Note The sender wheel must not be taken out of the sealing flange or rotated out of position.

l  Locating hole -A- on sender wheel -C- must align with marking -B- on sealing flange. –  Secure the sealing flange by the front on a flat, clean surface.

–  Press the sealing lip pressure ring -A- in the -direction of the arrow- downwards until it rests on the flat surface.

l  The upper edge of the sender wheel and the front edge of the sealing flange must align -arrows-.

–  Place the front of the sealing flange on the fitting device -T10134-, so that the fastener -B- sits into the hole -A- in the sender wheel.   Note Ensure the sealing flange lies completely on the assembly tool.

–  Tighten the sealing flange and the sealing lip pressure ring -B- while tightening the three knurled bolts -A- on the surface of the fitting device -T10134- so that the fastener cannot come out of the hole in the sender wheel.   Note When installing sealing flange, ensure that sender wheel remains fixed in assembly device.

B - Fit the centre guide -T10134-with the sealing flange on the crankshaft flange l  The crankshaft flange must be free of oil and grease. l  The engine is in TDC of cylinder 1. –  Screw hexagon nuts -B- to end of threaded spindle. –  Press the threaded spindle on the centre guide -T10134- in the -direction of the arrow- until the hexagonal nut -B- sits on the installation bell -A-.

–  Point the flat side of the installation socket towards the sealing surface of the engine block in contact with the oil sump. –  Secure the centre guide -T10134- on the crankshaft flange, for this purpose, screw in the Allen bolts -A- to the crankshaft flange by approx. 5 rotations of thread.

–  Screw in the 2 bolts M7×35 -A- on the engine block to guide the sealing flange.

C - Bolt the centre guide -T10134- to the crankshaft flange: –  Move the installation bell -C- by hand in the -direction of the arrow- until the sealing lip pressure ring -B- sits on the crankshaft flange -A-. –  Insert the guide pin for diesel engines (black handle) -D- into the crankshaft hole. In this way, the final fitting position of the sender wheel is established.   Note The guide pin for petrol engines (red handle) -F- cannot be inserted into the threaded hole. –  Tighten the Allen bolts of the fitting device by hand. –  Screw hexagon nut -E- onto threaded spindle by hand until it lies on assembly housing -C-.

D - Press the sender wheel with the centre guide -T10134- onto the crankshaft flange: –  Using the sealing support 24 -SAT 8010/24C-, tighten the hexagonal bolt of the centre guide -T10134- to a torque of 35 Nm.   Note A small air gap must be present between cylinder block and sealing flange after tightening hexagon nut to 35 Nm.

E - Check the fitting position of the sender wheel on the crankshaft. –  Screw hexagon nut -E- to end of threaded spindle. –  Unscrew the 2 bolts -A- of the engine block. –  Unscrew the knurled bolts -B- from the sealing flange. –  Remove the centre guide -T10134-. –  Remove the pressure ring from the sealing lip.

l  The sender wheel is positioned correctly on the crankshaft if the distance -a- between the crankshaft flange -A- and sender wheel -B- is 0.5 mm.

–  Fit the dial calliper onto the crankshaft flange. –  Measure the distance -a- between crankshaft flange and sender wheel. If distance -a- is too small: –  Re-press sender wheel → Anchor. If distance -A- is attained: –  Carry out the remaining installation operations → Anchor. F - Rectify the position of the sender wheel

–  Secure the fitting device -T10134--A- to the crankshaft flange; to do so, tighten the Allen bolts by hand –  Slide fitting device -T10134- onto the sealing flange by hand.

–  Screw hexagon nut -E- onto threaded spindle by hand until it lies on assembly housing -C-.

–  Using the sealing support 24 -SAT 8010/24C-, tighten the hexagonal bolt of the centre guide -T10134- to a torque of 40 Nm. –  Check the fitting position of the sender wheel on the crankshaft once more → Anchor. If distance -a- is again too small: –  Using the sealing support 24 -SAT 8010/24C-, tighten the hexagonal bolt of the centre guide -T10134- to a torque of 45 Nm. –  Check the fitting position of the sender wheel on the crankshaft once more → Anchor.

Assembly –  Screw in the new securing bolts -1 ... 6- of the sealing flange alternatively in the diagonal sequence.

–  Fit the engine speed sender -G28--1-. –  Install sump → Chapter.

–  Fit intermediate plate on sealing flange, and press onto dowel sleeves -arrows-. –  Install flywheel using new bolts. Tighten the attachment bolts to the torque 60 Nm + 90° (1/4 turn) → Chapter Tightening torques
