WebThe crosshatch angle should be consistent throughout the cylinder walls. If the crosshatch angle is too steep the cylinder walls will not retain sufficient oil to aid in the rings seating process. The problem is that the rings will pump oil and rings will rotate too quickly leading to accelerated ring and ring groove wear. WebCylinder Prep - Cross Hatch Pattern Maintaining the proper cross hatch angle is important for two reasons: 1) Oil retention on the cylinder wall 2) The rate of ring rotation. Excessively shallow cross hatch angles can hinder or slow down the necessary ring rotation that allows dissipation of heat.
