7. Cylinder / Piston
7-6
Measure the outer diameter of piston pin.
Service Limit (LX40A) : 19.960 mm
Service Limit (LX60A) : 21.960 mm
Measure the inner diameter of connecting rod
small end.
Service Limit (LX40A) : 20.064 mm
Service Limit (LX60A) : 22.071 mm
Measure the inner diameter of piston pin hole.
Service Limit (LX40A) : 20.020 mm
Service Limit (LX60A) : 22.020 mm
Calculate clearance between piston pin and its
hole.
Service Limit: 0.020 mm
Measure the piston outer diameter.
Caution
The measurement position is 10 mm distance
from piston bottom side, and 90° to piston pin.
Service limit (LX40A)：82.400 mm
Service limit (LX60A)：91.350 mm
Compare measured value with service limit to
calculate the clearance between piston and
cylinder.
