ABSTRACT:
A tool for extracting bearings from a long shaft as well as method of doing same is disclosed. This method and tool begins with connecting a split sleeve about a stuck bearing. This sleeve is then placed in a case. One or more extension are then added, thus allowing the puller to reach bearings on long shafts. When a sufficient number of extensions are added, a cap having an extraction bolt, which engages the end of the bearing shaft inside of the puller is attached. The extraction bolt is then rotated in a clockwise manner which forces the puller, and the engaged bearing, in an outward manner from the bearing shaft. When the extraction bolt is rotated to the extent of its working range by being turned all the way in, the puller is disengaged from the bearing and an extension section is then removed. This allows the extraction bolt to be rotated in a counter clockwise manner to a point were it regains its full working range. The present invention is then reengaged to the bearing shaft and bearing and the process is repeated until the bearing is completely removed from the bearing shaft.
