Forester F4-2.5L Turbo (2009)
^
When the timing belts are not installed, four camshafts are held at the "zero-lift" position, where all cams on camshafts are not pushing down on
the intake and exhaust valves. (Under this condition, all valves remain unlifted.)
^
When the camshafts are rotated to install the timing belts, #2 intake and #4 exhaust cam of camshaft LH are held, pushing their corresponding
valves down. (Under this condition, these valves are held lifted.)
^
Camshaft RH are held so that their cams do not push the valves down. Camshafts LH must be rotated by the smallest possible angle from zero-lift
position to where the timing belt can be installed, in order to prevent mutual interference of intake and exhaust valve heads.
^
Do not allow the camshafts to rotate in the direction shown in the upper figure. Doing this may cause both the intake and exhaust valves to lift
simultaneously, resulting in mutual interference of heads.
8) Install the timing belt.
Align the alignment mark on the timing belt with marks on the sprockets in the alphabetical order shown in the figure. While aligning marks, position
the timing belt properly.
CAUTION:
