Piston Fitting

Piston Fitting






The pistons are machined to two different weight specifications and matched to the rods based on weight. All piston and rod assemblies weigh the same to maintain engine balance.

The piston and cylinder wall must be clean and dry. The piston diameter should be measured 90 degrees to the piston pin at the location shown. Refer to => [ Piston, Pin and Ring Specifications ] [1][2]Piston, Engine. The cylinder bores should be measured halfway down the cylinder bore and transverse to the engine crankshaft center line. The pistons and cylinder bores should be measured at normal room temperature, 70 °F (21 °C).
