Fitting Pistons

FITTING PISTONS
All pistons are machined to the same weight in grams, to maintain piston balance.
Piston and cylinder wall must be clean and dry. Piston diameter should be measured 90 degrees to piston pin axis at size location shown in the illustration. Cylinder bores should be measured halfway down the cylinder bore and transverse to the engine crankshaft center line shown in the illustration.

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