29. ROTATE CRANKSHAFT AND CAMSHAFT
(a) Turn the crankshaft approximately 200° clockwise, and align the alignment mark as shown in the illustration.
NOTICE:
Do not turn the crankshaft counterclockwise except for a slight adjustment to correctly align the alignment mark. If not, the valves may come into contact with the piston.
(b) Using SST, turn the camshaft timing intake gear assembly LH approximately 180°clockwise, and align the alignment mark on the camshaft timing intake gear assembly LH to the position (zero-lift position) shown in the illustration.
SST : 09960-10010
09962-01000
09963-00700
NOTICE:
After this work, when the intake valve and exhaust valve lift at the same time, the valve heads contact each other, causing the valve stems to bend. To avoid this, do not turn the intake camshaft LH and the exhaust camshaft LH more than the zero-lift range (the range where the camshafts can be turned lightly by hand).
(c) Remove the pulley bolt.
