26. REMOVE CRANKSHAFT POSITION SENSOR PLATE
27. REMOVE TIMING BELT
(a) Set the No. 1 cylinder to approximately 45° BTDC/compression.
(1) Using the crankshaft damper 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 damper bolt, turn the crankshaft counterclockwise by approximately 45°.
NOTICE:
If the timing belt is disengaged, having the crankshaft pulley at a wrong angle can cause the piston head and valve head to come into contact with each other when removing the camshaft timing pulley and camshaft, causing damage. So always set the crankshaft pulley at the correct angle.
|
|
|
(b) 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.
|
|
|
(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) and crankshaft timing pulley by slightly turning the camshaft timing pulley (RH) counterclockwise.
SST: 09960-10010
