26. REMOVE NO. 1 TIMING BELT COVER





(a) Remove the 4 bolts and cover.
27. REMOVE CRANKSHAFT POSITION SENSOR PLATE
(a) Remove the crankshaft position sensor plate from the crankshaft.
28. REMOVE TIMING GEAR COVER SPACER





(a) Remove the cover spacer and gasket.
29. REMOVE TIMING BELT





(a) If planning to reuse the belt, check the installation marks on the timing belt.
(1) Check that there are 3 installation marks on the belt by turning the crankshaft as shown in the illustration.
If the installation marks have disappeared, place new installation marks on the belt before removing each part.
(b) Set the No. 1 cylinder to approximately 50° BTDC/compression.




(1) Using the crankshaft pulley bolt, turn the crankshaft to align the timing marks of the crankshaft timing pulley and oil pump body.




(2) Check that the timing marks of the camshaft timing pulleys and timing belt plates are aligned.
If not, turn the crankshaft 1 revolution (360°).




(3) Using the crankshaft pulley bolt, turn the crankshaft counterclockwise by approximately 45°.
NOTE:
With timing belt disengaged:

The crankshaft pulley must be at the correct angle to avoid damage in later steps. If the crankshaft pulley is at the wrong angle and then the camshaft timing pulley and the camshaft are removed, the piston head and valve head may come in contact and be damaged.
(c) Alternately loosen the 2 bolts. Then remove the 2 bolts, belt tensioner and dust boot.





(d) Using SST, loosen the tension between the camshaft timing pulley (RH bank) and crankshaft timing pulley by slightly turning the camshaft timing pulley (RH bank) counterclockwise.
