1、济南二手装载机磨合期磨损速度快，润滑不良
磨合期内容易造成零部件(特别是配合表面)的磨损，磨损速度快。这时，如果超负荷作业，则可能导致零部件的损坏，产生早期故障。另外，由于新装配的零部件的配合间隙较小，并且由于装配等原因，很难保证配合间隙的均匀性，润滑油(脂)不易在摩擦表面形成均匀的油膜以阻止磨损。从而降低润滑效能，造成机件的早期异常磨损。
Likely to cause run-in period parts (especially with the surface) of the wear, wear faster. At this time, if overload operation may result in damage to the components, resulting in premature failure. Further, since the new assembly with the gap of the parts is small, and due to assembly and other reasons, it is difficult to ensure uniformity with the gap, the lubricant (grease) of the friction surface is not easy to form a uniform film to prevent wear. Thereby reducing the effectiveness of lubrication, causing the early parts of abnormal wear.
2、济南二手装载机磨合期易发生松动
新加工装配的零部件，存在几何形状和配合尺寸的偏差，在使用初期，由于受到冲击、振动等交变负荷，以及受热、变形等因素的影响，加上磨损过快等原因，容易使原来紧固的零部件产生松动。
The new processing and assembly of components, there is a deviation geometry and with the size of the initial use, due to shock, vibration, etc. alternating load, and the effects of heat,deformation and other factors, coupled with excessive wear and tear and other reasons, easy to make the original loosening the fastening parts.
3、济南二手装载机磨合期易发生渗漏现象
由于机件的松动、振动合机器受热的影响，机器的密封面以及管接头登出会出现渗漏现象，部分铸造、加工等缺陷在装配调试时难于发现，但由于作业过程中的振动、冲击作用，这种缺陷就被暴露出来，表现为漏(渗)油(水)，因此，磨合期容易出现渗漏现象。
Since the sealing surface and the mechanical loosening of the pipe joint, the effects of vibration heating together the machine, the machine will be logged off leakage, part of the casting,machining and other defects in the assembly debugging difficult to find, but the vibration during operation, the impact role of this flaw is exposed, the performance of the leakage (permeation)(water), and therefore, prone to leakage of the run.
