Each of the motorists who at least once independently adjusted the thermal clearances of the valves of the gas distribution mechanism of the engine in a VAZ 2106 car knows firsthand how a third hand is lacking in the course of this work.
It is necessary
- - spanners 13 and 17 mm,
- - probe for valve clearances,
- - the key for the "ratchet".
Instructions
Step 1
Valve clatter caused by widened clearances is heard when the engine is running at idle speed. It disappears with increasing torque. If it is not removed in time, the valve may dry out and fall into the cylinder. And this threatens, at least, with a major overhaul of the motor or its replacement.
Step 2
Timing valve thermal clearances are adjusted on a cold engine. This parameter is based on a temperature equal to 20 degrees Celsius. Therefore, it is recommended to carry out work in the morning.
Step 3
At the beginning, the hood rises, and the engine crankshaft is set at the compression stroke of the TDC of the fourth cylinder, then the three nuts securing the air filter cover are unscrewed, and after removing it, four more nuts are unscrewed on the carburetor, and the body of the said device is finally dismantled.
Step 4
The plastic tip of the accelerator rod is disconnected from the carburetor, and its second end is released from its articulation with the shaft lever on the front panel of the engine compartment.
Step 5
After unscrewing ten nuts, the valve cover is removed and the tightening of the locknuts of the adjusting bolts 6 and 8 of the valves, the numbering of which starts from the front, from the radiator, is released alternately.
Step 6
Having set the gaps equal to 0.15 mm in the indicated place and turning the engine 180 degrees, proceed to the check, and, if necessary, adjust the specified parameters for 4 and 7 valves, then sequentially after the next cranking of the crankshaft by half a turn, adjust 1–3, and 5–2.
