z Measurement of cylinder bore Assemble the cylinder liner at the cylinder block and measure inner diameter at upper, middle, lower that 2 is, 3 steps by 45° interval and calculate the average values after eliminating the maximum and minimum values. EAMD067I z Measure the clearance between the cylinder liner bore and the piston outer diameter, if it is more than the use limit value, replace either one that is more severe. 3) Piston ring and ring groove a) Inspection z In case of piston ring’s wear, damage or engine overhaul, replace piston rings. b) Gap clearance z Measure the piston ring cut part. z Insert the piston ring at the cylinder liner’s upper part perpendicularly.
z With a feeler gauge, measure the Feeler gauge gap clearance of piston ring. z If the measured value exceeds the limit value, replace it.
