1. WARNING: Cover the end of the pin bore with a hand or shop rag when removing the retainer ring, since it has a tendency to spring
out. Wear eye protection.
NOTE: Piston and piston pins are a matched set and should not be interchanged.
Measure the piston pin bore diameter in two directions on each side. Verify the diameter is within specification.
^
If out of specification, install new components as necessary.
Piston-Diameter
1. Measure the piston diameter 90 degrees from the piston pin and 42 mm down from the top of the piston at the point indicated.
^
If out of specification, install new components as necessary.
Piston-to Cylinder Bore Clearance
Subtract the piston diameter from the cylinder bore diameter to find the piston-to-cylinder bore clearance.
Piston-Selection
NOTE: The cylinder bore must be within the specifications for taper and out-of-round before fitting a piston.
1. Select a piston size based on the cylinder bore.
