Checking the technical condition of timing parts
Sprockets, hydraulic tensioner, chain guide and tensioner arm
Power units are designed for operation at ambient temperatures from minus 60ºС to plus 50ºС, relative humidity up to 98% at a temperature of 25ºС, air dust content up to 0.4 g / m 3, as well as for movement car in mountainous conditions at an altitude of up to 4500 m above sea level and overcoming passes up to 4650 m above sea level with a corresponding decrease in power and economic indicators.
Checking and adjusting the valve clearance must be done on a cold engine (coolant temperature 20˚С), with the cylinder head mounted on the block
The cylinder block is cast in gray cast iron.
There are coolant channels between the cylinders
Adjusting the content of carbon monoxide (CO) in exhaust gases ZMZ-406
The adjustment is made on a warm engine (coolant temperature 80-90 ° C) with a working ignition system and nominal gaps between the spark plug electrodes
