Piston Ring Gap
1) Horizontally assemble the piston ring into
cylinder liner.(original place).
2) Push inverted the piston ring to be reached (1) & (2)
The cylinder liner diameter is the smallest at
these two points.
Perfectly horizontalize to set up without a
slant.
Cylinder Liner Measuring Point ; 10mm
Cylinder Liner Measuring Point ; 130mm
3) Measure piston ring gap with a feeler gauge.
Replace piston ring if the measured value
escaped from the specified limit.
Piston Pin
<Piston Pin Outside >
Measure the various placed pin outside with
micrometer.
Replace the pin if the measured value escaped
from the specified limit.
Piston Pin and Piston Clearance
Measure diameter of tne pin hole with inside
dial gauge.
