Dimension	Cylinder Bore Diameter
Standard dimension	82.51 mm

NOTE:

A shadow or a shiny spot on the wall of the cylinder does not mean the cylinder bore is damaged as long as the cross-lapping is still visible.

The cylinder bore must not be measured when the cylinder block is mounted on the :VAS6095A because the measurements may be incorrect.
