Flywheel

 The description of procedures of removal, check of a condition and flywheel installation is resulted in Section Removal, check of a condition and installation of a flywheel/privodnogo of a disk of the Head the Engine.


The flywheel, besides function of maintenance of start of the engine, serves also for transfer of a twisting moment from a cranked shaft to a transmission.

On the models which are let out for the markets of Europe and Australia, the flywheel of two-section type consisting of two inertial disks and a spring insert, placed between them is established.

The twisting moment of the engine from a cranked shaft is transferred at first to a primary disk of a flywheel, and then on the spring insert providing smoothness of transfer of a twisting moment to a secondary disk. As a result the stabilised twisting moment is transferred to a primary shaft of transmission through a coupling disk.

On the models which are let out for the other countries (USA), the flywheels of flexible type consisting of a leading disk, a strengthening insert and an inertial disk are used.

Coupling

On all models equipped РКПП, one-disk coupling of dry type with диафрагменной a spring is used. The nave of a frictional (conducted) disk of coupling is equipped longitudinal шлицами, entering into gearing with шлицами pins of a primary shaft of a transmission. Frictional and press coupling disks are kept in contact with each other at the expense of the effort developed диафрагменной by a spring of a press disk.

Coupling deenergizing is made in the hydraulic way. The deenergizing drive consists of a pedal of the coupling equipped with the tank of the main hydraulic cylinder, connecting lines and the executive cylinder affecting the lever of deenergizing of coupling and выжимной the bearing.

At squeezing of a pedal of coupling in a system path hydraulic pressure rises, результирующее which influence is put to the external end of the lever of deenergizing. At turn the lever rests fingers in выжимной the bearing which, being displaced, nestles on petals диафрагменной springs of a press disk in assemblage of a basket of coupling. Being curved, the spring deduces press and conducted disks of coupling from gearing, interrupting with that transfer of a twisting moment from the engine to a transmission. Details of installation of components of coupling are shown on illustrations.

At coupling service, besides replacement of the components having obvious mechanical damages, it is necessary to make some primary checks (it is supposed that the transmission is in good repair):

a) First of all it is necessary to make check of level of a liquid in the tank of the main hydraulic cylinder of coupling (the Section Check of level and replacement of a hydraulic liquid of a drive of deenergizing of coupling see). In case of need execute corresponding updating, having added demanded quantity of a fresh hydraulic liquid of a demanded grade, and attentively examine system on presence of signs of leaks. At a devastation of the tank of the main cylinder it is necessary to remove air stoppers (see Has undressed Removal of air from a hydraulic path of a drive of deenergizing of coupling) from a hydraulic path, then to check up serviceability of functioning of coupling;
b) For an estimation of time of switching of coupling start the engine on normal turns of idling. Make sure that neutral transfer is included and release a coupling pedal. Now squeeze out a pedal of coupling and, having waited for some seconds, include a reverse gear. Switching should not be accompanied by a gnash and other extraneous noise, with high degree of probability specifying in malfunction of a conducted disk or assemblage of a basket of coupling;
c) For check of completeness of deenergizing of coupling cock a lay brake and start the engine. Keeping a coupling pedal at height about 13 mm over a floor, попереключайте a box between the first and back transfers. Presence of hindrances at lever switching speaks about malfunction of components of the mechanism of deenergizing. Estimate size of a course of a pusher of the executive cylinder of coupling, - at completely squeezed out pedal the pusher should be put forward on appreciable size, otherwise it is necessary to check up level of a hydraulic liquid in the tank of the main cylinder;
d) Make visual check of a condition of axial plugs in the top part of a pedal of coupling. Make sure of absence of signs of jamming and excessive люфта axes;
e) Having got under the car, make sure of reliability of landing of the lever of deenergizing of coupling on a finger of a spherical support.
