Lift timing chain and place camshaft timing gear carefully on the camshaft. In order to have sufficient play in the timing chain, turn the loosened camshaft controller back and forth if necessary. Place timing chain on camshaft timing gear.
Fit screw for camshaft timing gear and screw it in loosely.
Screw in the four screws of the sprockets and camshaft controller as far as possible (it must still be possible to turn the sprockets and camshaft controller to adjust the timing).
Set the timing. → 150516 SETTING TIMING FOR CAMSHAFTS Do not tighten the sprockets and camshaft controllers to the final Tightening Torque until the timing has been set.
