GRM drive details: 1 – lower cover of the GRM drive; 2 – pulley of a bent shaft; 3 – belt of the drive of auxiliary units; 4 – bolt of fastening of a pulley of a bent shaft; 5 – bolt of fastening of the cogged pulley of a bent shaft; 6 – gear belt of the GRM drive; 7 – tension roller of a gear belt of the GRM drive; 8 – bolt of fastening of a tension roller; 9 – bolts of fastening of the top cover of the GRM drive; 10 – top cover of the GRM drive; 11 – back cover of the GRM drive; 12 – back arm of fastening of TNVD; 13 – TNVD; 14 – forward arm of fastening of TNVD; 15 – TNVD cogged pulley; 16 – pulley of an intermediate shaft; 17 – bolt of fastening of a pulley of an intermediate shaft; 18 – cogged pulley of a bent shaft; 19 – the lower cover of the GRM drive (for completely closed drive); 20 – the top cover of the GRM drive (for completely closed drive); 21 – a back cover of the GRM drive (for completely closed drive)


– remove a pulley 2 (see fig. 3.64 ) a bent shaft;
– take off a gear belt of the GRM drive (see subsection 3.3.4);
– turn off a bolt of the 5th fastening of the cogged pulley of a bent shaft and remove a pulley 18. For this purpose it is necessary to block a bent shaft from a provorachivaniye. On cars with the mechanical transmission include the fifth transfer and slow down the car the parking brake, with the automatic transmission — remove a forward cover of the transmission and the screw-driver or mount block a bent shaft for a gear wreath of a flywheel.
Installation of the cogged pulley of a bent shaft is carried out in the following order:
– clear the interfaced surfaces of the cogged pulley and a bent shaft;
– install the cogged pulley 18 (see fig. 3.64 ), having combined a pulley nave ledge with a flute on cranked to a shaft;
– tighten a bolt of the 5th fastening of the cogged pulley the moment of 90 N · m, then tighten it on a corner 90 °;
– establish a gear belt of the GRM drive (see subsection 3.3.4);
