Disconnect a wire of "weight" from the storage battery.
Remove from spark plugs tips with high-voltage wires or coils of ignition and take them aside from a cover of a head of the block of cylinders.
Stream of compressed air clear a place round spark plugs to exclude dirt hit in the cylinder of the engine after a reversing of candles. Turn out spark plugs.
Uncover heads of the block of cylinders.
Turning a cranked shaft of the engine in a direction of its working rotation for a bolt of fastening of a pulley, establish the piston of the first cylinder in the top dead point (ВМТ) in the end of a compression step.

Turn a cranked shaft on one turn (the piston of the fourth cylinder in
ВМТ in the end of a compression step) and measure backlashes on other valves (
fig. 2.50). Write down results of measurements.
