2.1.1.17. Gas distribution mechanism drive chain

Fig. 2.25. Gas distribution mechanism drive chain: 1 – camshaft asterisk; 2 – lever of a natyazhitel; 3 – natyazhitel of a chain; 4 – sending to a chain; 5 – asterisk of a bent shaft; 6 – gas distribution mechanism drive chain; 7 – step size; 8 – step; 9 – communication


Engine oil in a forward cover of the engine greases a chain of the drive of the mechanism of gas distribution and an asterisk. Pins of a chain of the drive of the mechanism of gas distribution are nitrated for increase in resistance to attrition (fig. 2.25).
