2.5 Cylinder Liner Inside Diameter - Measure
Measure the inside diameter of the cylinder liner at three
levels, i.e., upper (position of No.1 compression ring when
piston is at the top dead center), liner middle position, and
O-ring installed position, in both parallel and perpendicular
directions to the piston pin direction.
Replace the cylinder liner if the value exceeds the limit.If
the liner is distorted, pull-out the liner and re-install paying
attention to O-rings.

2.6 Piston and Connecting Rod - Assemble
(1) Apply engine oil to the piston pin, and assemble the
piston and the connecting rod.The orientation of piston
and connecting rod is shown in the illustration.
Note: The piston and piston pin are made for a clearance fit.
However, the piston pin is more easily inserted into the
piston if the piston is warmed up with a heater or with
hot water.
(2) Install the snap ring with ring pliers.Make sure that the
snap ring is fully inserted into the ring groove.
