Removal Procedure
1. Position the number 1 cylinder to A TDC 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.
NoticeIn 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.
