Press fit the sealing flange with the sender rotor   Note! t  Progressive introduction of a new generation of sealing flanges with PTFE (Teflon) seal. The sealing flange with elastic washer is still available as a replacement part. When fitting a new sealing flange, use only the type of flange previously fitted. t  The sealing flange with PTFE seal comes with a support ring in the sealing lip. This support ring functions as a fitting sleeve and cannot be removed before fitting. t  After unpacking, do not separate the sealing flange and sender rotor or change their position. t  The sealing surface of the sealing flange with elastic washer to the crankshaft has an elastomeric coating. This coating must always be kept clean and grease-free. t  The sender rotor is in its fitting position when it is fixed over the positioning pin of fitting tool -T10017-. t  The sealing flange and seal make up a single unit and can only be replaced along with the sender rotor. t  The fitting position of the -T10017- with respect to the crankshaft is predetermined by a guide pin that is inserted in the threaded hole of the crankshaft.

A - Hexagonal nut B - Fixing surface C - Fitting bell D - Allen bolt E - Guide pin F - Positioning pin A - Fit the sealing flange with the sender rotor in fitting tool -T10017-

–  Unscrew or screw the hexagonal nut -A- as far as the fixing surface -B- of the threaded shaft.

–  Unscrew or screw the hexagonal nut -A- as far as the fixing surface -B- of the threaded shaft. –  Press down on the fitting bell -C- such that it rests on the hexagonal nut -A- (arrow).   Note! The interior of the fitting tool and fitting bell must be at the same level.

–  Remove the safety clip -A- from the new sealing flange.   Note! Do not remove the sender rotor from the sealing flange and do not change their position with respect to each other.

–  The fixing hole -B- of the sender rotor -C- must coincide with the mark -A- on the sealing flange.

–  Place the sealing flange by the front part on a clean flat surface. –  Press the sender rotor (support ring of the sealing lip next to the PTFE seal) -A- in the direction of the arrow downwards until it rests on the flat surface.

–  The upper edge of the sender rotor and the front edge of the sealing flange must coincide -arrows-.

–  Position the front part of the sealing flange over fitting tool -T10017-, such that the positioning pin -A- enters the hole -B- in the sender rotor.   Note! Check that the sealing flange rests fully over the fitting tool.

–  When tightening the knurled bolts -A- on the surface of the fitting tool, press on the sender rotor (support ring of the sealing lip next to the PTFE seal) -B-, such that the positioning pin cannot come out of the hole in the sender rotor.   Note! Ensure that the sender rotor is secured in the fitting tool when fitting the sealing flange. B - Fit fitting tool -T10017- with sealing flange in the crankshaft flange. Conditions l  The crankshaft flange must be clean (oil and grease-free). l  The engine at TDC cyl. 1. Work sequence

–  Unscrew the hexagonal nut -A- until the end of the threaded shaft. –  Press the threaded shaft of the fitting tool in the direction of the arrow until the hexagonal nut -A- comes into contact with the fitting bell -C-. –  Face the flat part of the fitting bell towards the sealing surface of the engine sump pointing at the oil sump.

–  Fix the fitting tool with the Allen bolts -A- to the crankshaft flange.   Note! Fix the Allen bolts -A- approx. 5 turns in the crankshaft flange.

–  Screw in two bolts M6 x 35 mm -A- in the engine block to the guide the sealing flange. C - Bolt fitting tool -T10017- to the crankshaft flange

–  Slide by hand the fitting bell -A- in the direction of the arrow until the sender rotor (support ring of the sealing lip next to the PTFE seal) -B- rests on the crankshaft flange -C-.   Note! During fitting, the guide pin -D- of the fitting tool is inserted in the threaded hole of the crankshaft. In this way the definitive fitting position of the sender rotor is determined. –  Hole the fitting bell in this position and hand tighten the two Allen bolts of the fitting tool. –  Screw by hand the hexagonal nut -E- on to the threaded shaft until it comes into contact with the fitting bell -A-. D - Press the sender rotor with fitting tool -T10017- over the crank- shaft flange

–  Tighten the hexagonal nut of the fitting tool with torque spanner -SAT 8010- and ring spanner -SAT 8010/24C-. Tightening torque: 35 Nm   Note! After tightening the hexagonal nut to 35 Nm, a small space must remain between the engine block and the sealing flange. E - Check the fitting position of the sender rotor on the crankshaft –  Unscrew the hexagonal nut -A- until the end of the threaded shaft. –  Unscrew two bolts M6 y 35 mm -B- of the engine block. –  Unscrew the three knurled bolts -C- of the sealing flange. –  Move back the fitting bell -D- of the fitting tool as far as the hexagonal nut -A- (only in the sealing flange with elastic washer).

The fitting position of the sender rotor on the crankshaft is exact if there is a distance -a- of 0.5 mm between the crankshaft flange -A- and the sender rotor -B-.   Note! t  On the sealing flange with PTFE seal, unscrew completely fitting tool -T10017- and remove the support ring of the sealing lip. t  To facilitate the identification of the dimension -a-, the crankshaft flange is shown without fitting tool -T10017- screwed on.

–  Place a calliper against the crankshaft flange -A- (marked surface).

–  Measure with a feeler gauge -A- the distance -a- between the calliper and the sender rotor. If the distance -a- is not enough: –  Retighten the sender rotor → Anchor. If the distance -a- is OK: –  Remove the fitting tool. –  Screw on the new fixing bolts of the sealing flange alternating in a cross pattern. Tightening torque: 12 Nm

–  Fit the engine revs sender -arrow-. Tightening torque: 5 Nm –  Fit the oil sump → Chapter. –  Fit the intermediate plate. –  Fit the engine flywheel with new bolts. To do so immobilise the flywheel with countersupport -T20075A-. Tightening torque: 60 Nm + 1/4 turn (90o) F - Rectify the position of the sender rotor

–  Move the fitting bell -A- by hand towards the sealing flange -B-. –  Screw in two bolts M6 x 35 mm -C- in the engine block to the guide the sealing flange -B-. –  Screw by hand the hexagonal nut -D- on to the threaded shaft until it comes into contact with the fitting bell -A-.

–  Tighten the hexagonal nut of the fitting tool with torque spanner -SAT 8010- and ring spanner -SAT 8010/24C-. Tightening torque: 40 Nm –  Recheck the fitting position of the sender rotor on the crankshaft → Anchor. If the distance -a- is still not enough: –  Tighten the hexagonal nut of the fitting tool to 45 Nm. –  Recheck the fitting position of the sender rotor on the crankshaft → Anchor.
