Common faults Square Drive Hydraulic Torque Wrenches include abnormal wear and tear, abnormal noise of camshaft and fracture

Common faults Square Drive Hydraulic Torque Wrenches include abnormal wear and tear, abnormal noise of camshaft and fracture, abnormal sound and are often the first symptoms of abnormal wear before a fracture occurs.
(1) the end of the camshaft is located in the engine lubrication system, therefore lubrication is not so optimistic.If the oil pump for long time and other reasons for the oil pressure is low, road blockage caused by lubricating oil or lubricating oil cannot reach the camshaft, or bearing cap bolts tightening torque caused by excessive oil from entering the camshaft clearance will result in abnormal wear of the cam shaft.
(2) abnormal wear will cause the camshaft and camshaft bearings increase the space between, axial displacement occurs when the camshaft movement, resulting in abnormal noise.Abnormal wear or cause-driven cam gap increases with hydraulic tappets, 
HighReach torque tools will impact when combined with hydraulic tappet, resulting in abnormal noise.
(3) the camshaft will sometimes appear to break a serious fault, common causes of hydraulic tappet broken or badly worn, severe lubrication, poor quality of camshaft and camshaft timing gear breakdowns.
(4) in some cases, camshaft failures is human-caused, especially maintenance disassembly of the engine the camshaft without properly.For example, when removing the camshaft bearing cap with a hammer strength tap or use a screwdriver to pry, or install a bearing cap to misplace the bearing cover and housing do not match, or bearing cap bolts tightening torque is too large.
