Timing Component Alignment Marks: Locations

CAUTION:  Incorrect removal or installation of the timing belt can result in damage to internal engine components.

For complete Timing Belt Removal and Installation information, please refer to Timing Belt; Service and Repair.  See: Timing Belt/Service and
Repair

IF RE-USING TIMING BELT, CHECK INSTALLATION MARKS ON TIMING BELT

Check that there are 3 installation marks on the timing belt by turning the crankshaft pulley as shown in the illustration.

HINT:  If the installation marks have disappeared, place a new installation mark on the timing belt before removing each part.

SET NO.1 CYLINDER TO APPROX. 50° ATDC/COMPRESSION

a. Turn the crankshaft pulley and align its groove with timing mark "0" of the No.1 timing belt cover.

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

c. Turn the crankshaft pulley approx. 50° clockwise, and put the timing mark of the crankshaft pulley in line with the centers of the crankshaft

pulley bolt and the idler pulley bolt.

NOTICE:  If the timing belt is disengaged, having the crankshaft pulley at the wrong angle can cause the piston head and valve head to come
into contact with each other when you remove the camshaft timing pulley (step 19), causing damage. So always set the crankshaft pulley at the
correct angle.
