Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Engines>> Petrol engines of configuration of R4>> Flywheel
Removal of a flywheel is carried out in the following sequence:
– remove from the car the power unit (the engine, coupling and a transmission assembled);
– disconnect from the engine a transmission and coupling;

Fig. 3.22. Flywheel fixing by the special adaptation


– fix a flywheel from a provorachivaniye the special adaptation (fig. 3.22) ;
– unscrew bolts of fastening and remove a flywheel from a shaft of a cranked shaft;
– put with a label marker on a flywheel and a shaft of a cranked shaft for the subsequent correct installation of a flywheel.

Fig. 3.23. Fixing of a leading disk by the special adaptation


On models with an automatic transmission (AKP) on a shaft of a cranked shaft the leading disk to which the hydrotransformer fastens is established. The sequence of removal of a leading disk is similar to sequence of removal of a flywheel (fig. 3.23, 3.24) .
Defektovka of a flywheel includes:
– survey of a gear wreath. In the presence of broken or strongly worn-out teeths it is necessary to replace a gear wreath or a flywheel;
– survey of a working surface of a flywheel — surfaces of contact to a conducted disk of coupling. At existence on it of flutes, scratches or strong development surface polishing in a specialized workshop with the subsequent balancing of a flywheel or its replacement is necessary.

Fig. 3.25. Provision of a label of the moment of ignition: 1–VMT label; 2–label of the moment of ignition; mm A=14,5


Installation of a flywheel is carried out in sequence, return to removal. On a new flywheel there is only VMT label, a label of the moment of ignition it is necessary to put (fig. 3.25) . The distance of A is equal 14,5 mm at coal of an advancing of ignition 6 ° to VMT. On a carving of new bolts put the special means interfering their otvorachivaniye.

Fig. 3.24. Leading disk: 1–leading disk; 2–bolt of fastening of a leading disk; 3–clamping plate; 4–adjusting washer


At replacement of a leading disk (on cars from AKP) it is necessary to adjust A distance (fig. 3.26) from the back plane of the block of cylinders to an adjusting surface of the hydrotransformer which should be 19,5–21,1 mm. It changes an adjusting washer 4 (see fig. 3.24 ).
At installation it is recommended to establish new bolts of fastening of a flywheel or a leading disk. Before installation put special glue for fixation of bolts from an otvorachivaniye. Before an inhaling of bolts of fastening of a flywheel fix a flywheel from a provorachivaniye (see fig. 3.22, 3.23 ).
