Heat Treatment In very simple words I am going to explain the heat treatment process consists of a succession of heating and cooling cycles applied to a metal or alloy in order to obtain the desired properties such as hardness ductility tensile strength toughness grain size etc
For most machine designs this is abnormal because preferred lubrication methods provide a lubricant film between loadbearing surfaces Inadequate lubrication results in boundary lubrication due to one of four reasons no lubricant low viscosity excessive loading or slow speed or a combination of these
Proper selection of bearings will go a long way toward a successful engine build And checking assembled bearing clearances to make sure the bearings are not too tight or too loose should always be done as a final check to make sure oil clearances are within the desired range for the engine
