Cylinder Honing

It is a standard step in an engine rebuild. The cross-hatch pattern holds a thin film of oil. Some coated cylinders cannot be honed in the usual way. Plateau honing removes peaks from the surface after the main hone, which helps the rings bed in faster. The honing angle and finish follow the manufacturer's specification.

Rotating abrasive stones are moved up and down the bore to create the cross-hatch pattern and true the surface.

Cylinders must be thoroughly cleaned afterwards to remove abrasive particles. Bores worn beyond limits need reboring or sleeves rather than honing.
