Pistons-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, 900 to piston pin axis location A in. 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).
