Engine Valve Lash - Inspect/Adjust
新发动机、重新装配的发动机或再制造的发动机的初次气门间隙调整建议在首次定期换机油时进行。 由于阀系部件的初始磨损和磨合就座，初期调整是必要的。
作为润滑和预防性保养计划的一部分，卡特彼勒推荐这项保养内容，这样有助于延长发动机的使用寿命。
电子单体喷油器的调整
以与气门间隙调整的同样时间间隔，调整电子单体喷油器（预装）。 在电子单体喷油器调整不当的情况下运行卡特彼勒发动机可能降低发动机的效率。 效率的降低可能导致燃料消耗量增加和/或缩短发动机部件寿命。

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。 |
