3. Remove yokes, blocks of axial pressure and hydraulic pushers from a head of the block of cylinders. Using the adaptation for compression of a spring of the valve, compress each spring and remove crackers from a valve end face. Remove the adaptation for compression of a spring and take a plate and a spring. Плоскогуб tsami, being careful, take a maslootrazhatelny cap from a valve rod. Take the bottom plate of a spring.
4. When the spring of the valve is compressed and the cup of a spring does not act in film from crackers, it is necessary to strike with a hammer through wooden whetstone on a spring cup that will lead to release of crackers.
5. Take the valve via the combustion chamber. Each valve store in a separate plastic bag together with a plate of a spring, a spring, a nest of a spring and crackers for their further installation on the places.
