● Measure the piston pin O.D.
Service Limit: ψ17.06mm replace if below
● Measure the piston O.D.
NOTE:
Take measurement at 10mm from the bottom and 90 to the
piston pin hole.
Service Limit: ψ72.60mm replace if below
● Measure the piston-to-piston pin clearance.
Service Limit: 0.025mm replace if over
CYLINDER INSPECTION
● Inspect the cylinder bore for wear or damage.
● Measure the cylinder I.D. at three levels of top, middle and
bottom at 90° to the piston pin (in both X and Y directions).
Cylinder I.D.:
Service Limit: ψ72.8mm replace if over
● Measure the cylinder-to-piston clearance.
Service Limit: 0.10mm repair or replace if over
The true roundness is the difference between the values
measured in X and Y directions. The cylindricity (difference
between the values measured at the three levels) is subject to the
maximum value calculated.
Service Limits:
True Roundness: 0.012mm repair or replace if over
Cylindricity: 0.012mm repair or replace if over
