开始:

  1. 拆下齿轮马达。 请参阅拆解和组装, "风扇和齿轮马达(液压风扇)- 拆卸"。

注: 清洁度是一项重要的因素。 拆解步骤开始之前,应彻底清洁部件外部。 这有助于防止尘土进入内部结构。 污染物或污垢可能会损坏精密部件。 拆解步骤应在清洁的工作面上进行。 务必盖上部件并采取适当保护措施。

注: 在泵和马达上作识别标记以便装配。


注意

保持所有零件清洁无杂质。

液压系统被异物污染会缩短液压系统部件的使用寿命。

为了避免污染物进入液压系统,总要在断开后塞住或盖住管路、管接头或软管。 罩住已解体的部件,然后在组装前正确清洁它们。

在更换任何主部件后,或特别是在部件故障后,正确清洁液压系统,以便去除全部污染物。
