Fig. 3.52. Bent shaft and flywheel: 1 – bent shaft; 2 – inserts of the conrod bearing; 3 – persistent half rings; 4 – inserts of the radical bearing; 5 – rod; 6 – bolt of fastening of a cover of a rod; 7 – gear wreath of the sensor of frequency of rotation of a bent shaft; 8 – bolt of fastening of a gear wreath; 9 – flywheel; 10 – bolt of fastening of a flywheel; 11 – adjusting pin of coupling

– record a flywheel 9 (see fig. 3.52 ) from a provorachivaniye, having established a clamp on a gear wreath of a flywheel;

– apply tags on a flywheel 9 and a bent shaft 1 for the subsequent correct installation of a flywheel;

– turn off bolts of the 10th fastening of a flywheel and remove a flywheel.

Fault detection of a flywheel includes check of a gear wreath on wear or damages of teeths, the basic surface of coupling on wear.

Installation of a flywheel is carried out in the following order:

– clear the interfaced surfaces of a flywheel and a bent shaft;

– establish a flywheel on pins of a bent shaft according to earlier put tags;

– screw new bolts of fastening of a flywheel;

– record a flywheel from a provorachivaniye, having established a clamp on a gear wreath of a flywheel;

– tighten bolts of fastening of a flywheel the moment of 70 N · m serially cross-wise, then tighten them on a corner 90 °;

– establish coupling and the transmission.

PREVENTION At installation of a flywheel it is recommended to use new bolts of fastening.
