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.

Installation Procedure
1. Check the piston ring gap and apply the engine oil to
the piston pin and the connecting rod bushing.
2. Connect the piston and the connecting rod by press-
ing in the piston pin (6) and install the snap ring to the
groove.
3. Clean the cylinder bore, connecting rod bearing jour-
nal, connecting rod bearing shell and the piston and
coat them with engine oil.
4. Install the piston ring.
5. Install the piston so that the arrow on the piston head
faces to the forward of the vehicle.
6. After aligning the connecting rod and the bearing cap
mark (// or a number), tighten the bolts.
