(1) 衬垫组件
(2) 垫片

注: 卡车应当停放在水平面上。 应当安装举倾油缸。

注: 应当安装车斗枢轴销。 请参阅拆解和组装, "销(车斗固定)- 拆卸和安装"。

  1. 以卡车车斗上的中央安装块为参考,标出机架导轨上衬垫组件 (1) 的位置。

  2. 升起卡车车斗并安装适当的安全装置,以将卡车车斗固定到上升位置。 在机架导轨上每个衬垫组件 (1) 的位置,叠装一个衬垫组件 (1) 和一个垫片 (2)。

  3. 拆下安全装置,然后降下卡车车斗。 查找存在的间隙,并通过加装垫片 (2) 消除间隙。

  4. 升起卡车车斗,然后安装适当的安全装置,以便将卡车车斗固定到上升位置。 通过螺栓将衬垫组件 (1) 和垫片组固定到卡车车斗上。 拆下安全装置后降下卡车车斗。
