只有有资格的维修人员才能进行该项保养工作。对于整个气门间隙调整步骤,请参考维修手册或与卡特彼勒代理商联系。 气门间隙调整不适当的卡特彼勒发动机工作效率会降低。 这样会使燃油消耗量增加和/或缩短发动机部件寿命。 |
新发动机、重装发动机或再制造发动机的初次气门间隙调整应在首次换机油时进行。 新发动机、重装发动机或再制造发动机的初次气门间隙调整必须在第四次换机油时或之前进行。由于气门系部件的初始磨损和磨合就座,调整是必要的。
作为润滑和预防性保养计划的一部分,这项保养内容有助于延长发动机的使用寿命。

进行该项保养时,确保发动机不会被起动。 不要使用起动马达带动飞轮,以免造成人身伤害。 热的发动机零部件可能造成烫伤。 在测量/调整气门间隙前要等一定时间,让发动机冷下来。 |
为了得到准确的测量结果,在进行该项保养前让气门先冷下来。
检查和调整气门时,应同时检查和调整以下部件。
- 气门旋转器
- 喷油器
- 压缩制动器
