The following points must be observed when using and maintaining the engine water pump: Correct installation. During installation, the gears of the gear driven pump should be closely combined with the transmission gear. The belt driven pump should ensure that the concentricity of the pump shaft and the pulley is within the specified range and prevent the pump from swaying due to the increase of the rotational speed or the load, which aggravates Wear and tear Correctly adjust the belt tightness. Fan belt can not be adjusted too tight, otherwise it will increase the pump bearing load. If it is more than two belt drive, to ensure that a few old and new, length, tightness consistent with each other to prevent uneven belt tension, the pump is not balanced and premature damage. Fill lubricant in time According to the instructions in the manual, timely filling of the pump bearing oil, the number of filling oil can not be too much or too little, to prevent premature bearing damage. Do not plug the overflow hole. Some pump shaft overflow hole, through the overflow hole can be observed whether the water pump leaks. If the overflow hole blocked, the water pump leaks into the bearing and affect the lubrication, causing premature bearing damage. Disassembly can not be hit hard knock. Overhaul the pump, remove the pulley and pump bearings and other major components of the application of special tools. If you hit the hard hard knock during installation, easy to cause bending deformation of the pump bearings, pump shaft shaft threaded slider or damage. Another impeller and pump shaft with tighter, unless necessary, generally do not disassemble. Timely remove the scale within the pump. Accumulation of too much scale within the pump, will pump water weakened capacity, while the scale will corrode the pump parts, easy to premature failure of the pump.
