Removal Procedure
1. Position the No.1 cylinder to TDC (OT).
Notice:Remove the oil filler cap at adjustment position,
and check whether the intake camshaft cam’s lobe (ar-
row) stays in the upper side.
2. Cover the generator with a clean cloth.
3. Release the tension by unscrewing the screw plug
once.
Notice:In case that the tension is reduced by unscrew-
ing the screw plug, reinstall after completely removing
the chain tensioner. If the chain tensioner is tightened
again without completely reducing its tension, then the
detent spring doesn’t return to the original position and
the tension gets exceeded.
