Piston: Service and Repair

All pistons are machined to the same weight in grams, to maintain piston balance.

Piston Size Location:

Cylinder Bore Size Measuring:

Piston and cylinder wall must be clean and dry. Piston diameter should be measured 90 degrees to piston pin axis. Cylinder bores should be measured halfway down the cylinder bore and transverse to the engine crankshaft center line. Refer to Specifications.

NOTE: Pistons and cylinder bores should be measured at normal room temperature, 70°F (21°C).
