拖拉机、柴油机的技术资料中提供的各种调整数据，通常是适合一般正常情况的。而旧的拖拉机、柴油机，特别是技术状态较差的机车，由于零件磨损较大，相关零件配合关系发生变化，调整数据的选择要有所不同，以便更好地发挥机具效能，延长使用寿命。现根据笔者在多年实践中的经 Tractors, diesel engine technical data provided in the various adjustment data is usually suitable for normal circumstances. However, the old tractors and diesel engines, especially the locomotives with poor technical status, have different wear-and-tear parts because of the wear and tear of the parts.
