1、濟南二手裝載機磨合期磨損速度快，潤滑不良
磨合期內容易造成零部件(特別是配合表面)的磨損，磨損速度快。這時，如果超負荷作業，則可能導致零部件的損壞，產生早期故障。另外，由于新裝配的零部件的配合間隙較小，并且由于裝配等原因，很難保證配合間隙的均勻性，潤滑油(脂)不易在摩擦表面形成均勻的油膜以阻止磨損。從而降低潤滑效能，造成機件的早期異常磨損。
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、濟南二手裝載機磨合期易發生松動
新加工裝配的零部件，存在幾何形狀和配合尺寸的偏差，在使用初期，由于受到沖擊、振動等交變負荷，以及受熱、變形等因素的影響，加上磨損過快等原因，容易使原來緊固的零部件產生松動。
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、濟南二手裝載機磨合期易發生滲漏現象
由于機件的松動、振動合機器受熱的影響，機器的密封面以及管接頭登出會出現滲漏現象，部分鑄造、加工等缺陷在裝配調試時難于發現，但由于作業過程中的振動、沖擊作用，這種缺陷就被暴露出來，表現為漏(滲)油(水)，因此，磨合期容易出現滲漏現象。
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.
