The bearing mounting device comprises a radially expandable sleeve having radially movable segments along the periphery thereof and a tapered, threaded bore. A bearing with a tapered, threaded outer diameter complementary to the threaded bore of the sleeve threadingly engages the bore of the sleeve, and tightening of the bearing into the bore expands the segments of the sleeve against the housing. With the tapered outer diameter of the bearing, when tightened securely in the bore the bearing and the sleeve are securely fixed in the housing. A spanner wrench is disclosed for rotating the outer race of the bearing into engagement with the sleeve, and a second spanner wrench is disclosed for preventing rotation of the sleeve during insertion of the bearing. | |
