Used heavy body abnormal sound of gears uneven sound: the engine idling issue "rattled" when running a rhythmic sound, chaff, when the throttle to "ga - ga" sound, serious feel gearbox vibration. This is due to the gear teeth raised bumps or missing teeth, a second shaft or intermediate shaft bending and gear center offset due. Guadang repeatedly suspended wheels can change the speed, if the sound more crisp, compared with teeth or tooth bumps, replace gear; if the sound dull and cluttered, medium chaff cutter, then mostly offset or second gear center shaft, intermediate shaft bending, chaff Which is good, you should correct gear shaft. Chaff Shaft Repair Method three: recovery journal size by welding method. When the chaff journal serious wear and tear, you can use welding method welding metal in the journal, and then processed to the original size, large chaff, which repair process is as follows: how are ready to talk about today before welding. In order to ensure a solid combination of surfacing and the original journal, it must be carefully removed before welding grease and dirt, accurate measurement of worn journal size to ensure that the weld metal thickness of not less than the end of the journal processed 1.5-2.0 mm Otherwise, it should first journal turning, then surfacing.
