- 应清洁所有的滚珠轴承。 轴承架空腔应填充 2S-3230 润滑脂 。 填充轴承(空腔容积的三分之一至二分之一)。
- 使用进气加热器以加热滚珠轴承至 107 °C (224.6 °F) 持续 10 分钟,以便安装以下任一轴承:新滚珠轴承 和 已检查的滚珠轴承。 将轴承安装在轴上。 为了重新安装轴毂,将轴毂加热至 400 °C (752.0 °F) 3 个小时。 把毂环安装到轴上。
- 确保黄油枪的注油管充满润滑脂。
- 拆去轴承架排放塞并运转发电机 1 个小时。 该步骤将使润滑脂膨胀。 膨胀的润滑脂将多余的润滑脂从空腔中挤出。 多余的润滑脂从空腔中挤出时,使内部压力降低。 继续运转发电机,直至润滑脂停止排出为止。
- 停止发动机。 安装轴承架排放塞。 擦去过量的润滑脂。
- 关于加注润滑脂的周期,应遵照润滑铭牌(如有配备)上的建议,或参考 保养周期, "发电机轴承 - 润滑"。 只要轴承需要加注润滑脂时,就要重复步骤1。 不得混用润滑脂。
