Cylinder Block Assembly: Testing and Inspection

Checking





- Measure at three locations diagonally in crosswise direction -A- and lengthwise direction -B-.
Inner bore gauge: 50 - 100 mm (1.96 - 3.94 inch)
Deviation from nominal size: maximum 0.08 mm (0.0031 inch)

Piston and cylinder bore dimensions





Engine codes ACK and AHA

Note: Replacement pistons are only available in the basic dimension.

CAUTION: DO NOT measure cylinder bore dimensions while the cylinder block is mounted on the engine stand. The cylinder block is stressed and deformed by its own weight under these conditions and the measurements will not be accurate.
