4.2.7. Check the clearance between the
piston and the cylinder wall The
positions for measuring the inner
diameter of the cylinder and the
piston skirt are as shown in the right
figure. Replace and repair the piston
or the cylinder body, or bore the
cylinder if the measured results
exceed the limits

[Reference]
The clearance between the
piston and the cylinder hole is subject to
the innermost diameter of cylinder in
vertical direction minus the maximum outer
diameter of the piston.

4.3. Crankshaft
4.3.1. Check the coaxiality of the main
shaft diameter
4.3.1.1. Use the centimeter to measure the
coaxiality.
Replace the crankshaft if the measurement
result exceeds t he limit.

Attention
: The bending value should be
1/2 of the fluctuation for one circle of
turning the crankshaft.
4.3.2. Check the tears and wears of the
crankshaft
4.3.2.1. Use a caliper to measure the shaft
diameter, and work out the
circularity and cylindricity.
