    • A sealing element which forms a seal between a groove and an outer end of a crankshaft is installed by the use of a guide plate, an adapter and a press. The sealing element can be stretched over a frustoconical wall of the guide plate and slid along the cylindrical wall thereof on the outer end of the crankshaft. An adapter is then secured to the outer end of the crankshaft so that the press may be engaged over the adapter in sliding contact therewith to move the sealing element along the outer end of the crankshaft and into the groove. The sealing element may be removed from the groove by a puller. A rim of the puller is aligned with the sealing element as a drill is extended through passages in the rim of the puller to form holes in the sealing element. Screws are extended through the passages and self-tap into the holes formed in the sealing element. The puller is then withdrawn to withdraw the seal from the groove.
    • 通过使用导向板,适配器和压力机安装在曲轴的槽和外端之间形成密封的密封元件。 密封元件可以在引导板的截头圆锥形壁上被拉伸,并且沿曲轴外端的圆柱形壁滑动。 然后将适配器固定到曲轴的外端,使得压力机可以与适配器接合以与其滑动接触,以使密封元件沿着曲轴的外端移动到凹槽中。 密封元件可以通过拉拔器从凹槽移除。 当钻头通过拉拔器的边缘中的通道延伸时,拉出器的边缘与密封元件对准,以在密封元件中形成孔。 螺丝通过通道延伸并自攻入形成在密封元件中的孔中。 然后拉出拉出器以从凹槽中取出密封件。
