Abstract

A bearing remover is configured to cooperate with a puller to remove a bearing from an axle. The bearing remover includes a claw that has an opening to receive a portion of the axle, and a lip that can be inserted between the bearing and the wall. The bearing remover also includes a centering component that fits about the axle. The claw and centering component are mechanically coupled to assist in maintaining the claw about the bearing, and to transmit a force to the claw.

Claims

1. A bearing remover configured to cooperate with a puller to remove a bearing from an axle, where a side of the bearing is positioned within 5 mm of a wall, comprising:

a claw having (a) an opening configured to receive a semi-circle portion of the axle, and (b) a lip sized and dimensioned to be inserted between the bearing and the wall; and

a centering component that fits about the axle, and mechanically couples the claw in a manner that assists in maintaining the claw about the bearing, and transmitting a pulling force to the claw.

2. The bearing remover of claim 1, wherein the claw is configured to receive a semi-circle portion of the axle of at least 20 degrees.

3. The bearing remover of claim 1, wherein the centering component further comprises a catch having sufficient strength to withstand the pulling force where the pulling force is at least 50 pounds.

4. The bearing remover of claim 1, wherein the lip has a horseshoe shape.

5. The bearing remover of claim 1, wherein the lip has a square shape.

6. The bearing remover of claim 1, wherein the lip has a triangular shape.

7. The bearing remover of claim 1, further comprising a mechanical coupling between the puller and the centering component such that the pulling force is transmitted from the puller to the claw.

8. The bearing remover of claim 1, further comprising an insert configured to adapt the lip to the bearing.

9. The bearing remover of claim 1, wherein the lip is sized and dimensioned to remove a steering stem bearing from a motorcycle.

10. The bearing remover of claim 1, wherein the lip is sized and dimensioned to remove a lower steering stem bearing from a Harley Davidson motorcycle built after 1948.
