Piston Selection

NOTE: To determine the piston to cylinder bore clearance perform the following measurements:

1. Measure the cylinder bore. If the bore is serviceable, note the lowest bore diameter measurement. Then compare this measurement to the piston measurement.
2. Measure the piston. Compare the piston measurement to the piston-to-cylinder-bore specifications found at the end of this section. Subtract the piston diameter from the lowest bore diameter to determine piston-to-bore-clearance.
3. If the used piston is not acceptable, determine if a new piston will fit the cylinder bore using the above measurement procedures.
