2.1.1.9. Forward cover of the engine
Fig. 2.15. Forward cover of the engine: 1 – vertical projection; 2 – a technological opening for fixing of the lever of a natyazhitel; 3 – a technological opening for an unblocking of a natyazhitel of a chain; 4 – arm of an engine mount No. 3; 5 – opening of an adjusting bolt of a pulley of a bent shaft; 6 – rear view; 7 – oil filter; 8 – the channel of the operating oil valve

The forward cover of the engine is made of aluminum alloy and is combined with an arm No. 3 of fastening of the engine that reduces the weight and noise level. An opening for an adjusting bolt of a pulley of a bent shaft, a technological opening for an unblocking of a ratchet of the regulator of a tension of a chain and a technological opening for fixing of the lever of a natyazhitel when weakening a chain of the drive of the mechanism of gas distribution, are on a forward cover of the engine. On L3 engine models the oil pipeline and the integrated oil filter are on a forward cover (fig. 2.15).
