• Measure the side clearance between connecting rod and crank-
shaft arm with feeler gauge.
• If the measured value exceeds the limit, replace connecting rod,
and measure again. If it still exceeds the limit, replace crankshaft
also.
PISTON TO PISTON PIN CLEARANCE
Piston Pin Hole Diameter
Measure the inner diameter of piston pin hole with inside microme-
ter.
Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pin hole diameter) – (Piston pin outer diameter)
• If the calculated value is out of the standard, replace piston and piston pin assembly.
• When replacing piston and piston pin assembly. Refer to EM-124, "How to Select Piston and Bearing"
.
NOTE:
• Piston is available together with piston pin as assembly.
• Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no
piston pin grades can be selected. (Only “0” grade is available.)
