4. Align the synchronization mark Stars.
5. Put the gas distribution belt on the sprocket and pulleys. and remove the blocking tool camshaft sprocket.
6. Turn the tensioner pulley and install the spring.
7. Turn the crankshaft two full turns and check the synchronization mark. When you rotate the crankshaft, stop when you feel resistance. Most likely due to incorrect combination of labels, refer to the piston valves. Check back tagging and only then proceed.
