Mains engine problem Brisbane - FLOGGED
This condition is referred to as fatigue failure. As the name suggests it occurs when the bearing is subjected to abnormal working conditions. Excessive loads can occur directly from driving conditions. More commonly the excessive loads are generated due to incorrect ignition or injector timing, poor fuel or extreme temperatures. Constant full throttle use while these conditions exist will result in bearing fatigue failure or flogged main bearings. Overloading is a term used to describe internally generated forces that destroy the properties of the bearing. Lugging an engine under extreme heavy conditions is a driver-induced cause of main bearing fatigue. If driver lugging is the cause of the main bearing failure usually the lower half of the bearing is more affected. (Lugging describes full throttle, heavy loads with low revs.) Consistent over reeving of the engine above what it was designed to do will result in flogged main bearings. Normally this condition would significantly effect the upper half of the main bearings. (Trucks often display this type of damage by using too low a gear as engine braking down steep inclines, the load weight causes the engine to rev above design specifications.)
