Cylinder Honing
The cylinder bore must be de-glazed whenever new piston
rings are installed.
A light honing with fine stones removes
only a very small amount of material. A proper
crosshatch pattern is important to provide a surface that
will hold oil, and allow the rings to seat properly. If the
crosshatch is too steep, oil retention will be reduced. A
crosshatch angle which is too shallow will cause ring vibration,
poor sealing, and overheating of the rings due to
blow-by and reduced contact with the cylinder wall. Service
life of the pistons and rings will be greatly reduced.
NOTE: A Nicasil cylinder can be lightly honed with a
diamond hone but can NOT be oversized.
