8 Seal
Removal Procedure
1. Position the number 1 cylinder to ATDC 20°.
Notice
Remove the oil filler cap at adjustment position, and check
whether the intake camshaft cam’s lobe (arrow) stays in the
upper side.
2. Cover the alternator with a clean cloth.
3. Release the tension by unscrewing the screw plug once.
Notice
In case that the tension is reduced by unscrewing the screw
plug, reinstall after completely removing the chain tensioner.
If the chain tensioner is tightened again without completely
reducing its tension, then the snap ring doesn’t return to
the original position and the tension gets excedded.
