cap.
2) Detach the connecting rod caps.
(Important)
• Apply engine oil to the connecting rod bolts and tighten
them to 26 to 30 Nm (2.7 to 3.1kgf·m, 20 to 22 ft-Ibs).

Removing Pistons
1) Turn the crankshaft by 3.14 rad (180°) and bring the
piston to top dead center.
2) Draw out the piston upward by lightly tapping it from the
bottom of the crankcase with the grip of a hammer.
3) Draw out the other two pistons in the same method as
above.
(Note for reassembling)
• Before inserting the pistons into the cylinders, apply
enough engine oil to the pistons.
(J

• Install the piston rings with their gaps making an angle
of 2.09 rad (120°) or 3.14 rad (180°) to each other. (Place
the top ring with their gaps on the opposite side of the
combustion chamber.)
• Attach a ring to the pistons securely with a piston ring
compressor, and set them to the cylinder, being careful
about the cylinder number and the position of the con ­
necting rod (Connecting rods must be installed with their
ends bearing the number toward the fuel injection pump).
• Carefully insert the pistons. Otherwise, their chrome ­
plated section may be scratched, causing trouble inside
the liner.
