ENGINE Cylinder Honing Cylinder Honing
The cylinder bore must be de-glazed whenever new piston rings are installedA light honing with fine stones removes only very small amount of materialA proper crosshatch panern is important to provide surface that will hold oil, and allow rings to seat properlyIf the crosshatch is too steep, oil retention will be reducedA crosshatch angle which is too shallow will cause ring vibrationpoor sealing, and overheating of the rings due to blow-by and reduced contact with the cylinder wallService life of the pistons and rings will be greatly reduced
Cylinder Hone Selection
Selecting hone which will straighten as well as remove material from the cylinder is very importantHoning cylinder with spring loaded glaze breaker is never advisedPolaris recommends using rigid type hone which also has the capability of oversizingThese hones are manufactured by such companies as Sunnen Products Company of StLouis, Missouri; and Ammco ToolsInc of North Chicago, Illinois
De-glazing
If cylinder wear or damage is minimal, hone the cylinder lightly with finish stones
