Piston: Procedures
STANDARD PROCEDURE - PISTON FITTING
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). Check the pistons for taper and elliptical shape before they
are fitted into the cylinder bore (Fig. 39).
