- Set crankshaft to TDC of Cylinder No.1 by turning crankshaft at vibration damper bolt.
If TDC for cylinder No.1 is OK you should see a notch (arrow) at the intermediate shaft sprockets.
If you cannot see the notch: Turn crankshaft one full turn in engine running direction.
NOTE: If you turn the crankshaft with the cylinder head removed, have another technician guid6 the double chain to avoid snagging.
