3. Check that the intermediate pulleys rotate freely.

Setting

PERFORMANCE ORDER
1. Carefully clean the installation area of the timing belt in the front of the engine.
2. Install the crankshaft sprocket.
3. Temporarily screw the crankshaft pulley bolt and rotate the shaft clockwise to align the mark on the crankshaft sprocket with the mark on the crankcase.
4. Set the gas distribution belt.
5. Set the tensioner (compressed by the piston and inserted into the bottom hole of the rod) and tighten the bolts.
6. Remove the rod from the hole tensioner. Rotate the crankshaft two full turns (720 ?�). Check whether the combined still synchronization labels of asterisks (see. Fig. Sinhronizatsionnye labels crankshaft Fig. Sinhronizatsionnye labels camshaft - front row of cylinders, Fig. Sinhronizatsionnye labels camshaft - a back row of cylinders).
A warning

Do not start the engine until then, until you are absolutely convinced that the gas distribution belt is correctly installed. If the belt is not installed properly, the engine may get serious damage.
