Piston: Service and Repair
Fitting Pistons
Piston and cylinder wall must be clean and dry. Specified clearance between the piston and the cylinder wall is 0.013-0.038 mm (0.0005-0.0015 inch) at
21°C (70°F).
Piston diameter should be measured at the top of skirt, 90° to piston pin axis. Cylinder bores should be measured halfway down the cylinder bore and
transverse to the engine crankshaft center line.
Pistons and cylinder bores should be measured at normal room temperature, 21°C (70°F).
Piston Measurements
Check the pistons for taper and elliptical shape before they are fitted into the cylinder bore.
