## Abstract

A puller tool and method for pulling a component from another component are provided. The puller tool can include a cross bar, a pair of puller legs that are movable along the length of the cross bar and a forcing screw. The puller legs can be quickly positioned anywhere along the length of the cross bar through a quick release mechanism. The cross bar can include notches on its outer surface to ensure that the puller legs are equidistant from each other during use.

## Claims

### Claim 1

A puller, comprising:
a cross bar;
a pair of puller legs that receives the cross bar and includes a foot at a lower end to engage a component being serviced;
a screw received in a middle portion of the cross bar, the screw having a first end and second end;
a quick release mechanism coupled to the puller legs to position the puller legs along a length of the cross bar, the quick release mechanism is configured to couple the puller legs at an infinite amount of positions along the cross bar; and
wherein the quick release mechanism includes a tab opening that receives the cross bar and at least one of either a top portion or a bottom portion of the tab opening engages the cross bar.

### Claim 2 (depends on 1)

The puller of claim 1, wherein the cross bar further comprises alignment notches that are used to align the puller legs so that they are evenly placed from each other on the cross bar.

### Claim 3 (depends on 1)

The puller of claim 1, wherein the puller legs include retaining tabs on an outside surface.

### Claim 4 (depends on 1)

The puller of claim 1, wherein the second end includes a tapered pointed end to engage the component being serviced.

### Claim 5 (depends on 1)

The puller of claim 1, where in the foot includes a curved engagement portion.

### Claim 6

A puller, comprising:
a cross bar;
a pair of puller legs that receives the cross bar and includes a foot at a lower end to engage a component being services;
a screw received in a middle portion of the cross bar, the screw having a first end and second end;
a quick release mechanism coupled to the puller legs to position the puller legs along a length of the cross bar, the quick release mechanism is configured to couple the puller legs at an infinite amount of positions along the cross bar;
wherein the quick release mechanism further comprises:
a tab portion;
a pin portion that extends from the puller legs and engages the thumb tab portion;
a spring means that biases the tab in an engaged position with the cross bar;
a middle portion that includes a tab opening portion that receives the cross bar; and
a lower portion coupled to the puller legs.

### Claim 7

A puller tool for servicing a component, comprising:
a means for supporting;
a means for engaging a component being serviced that receives the means for supporting and is supported by the means for supporting and includes a foot at a lower end to engage the component being serviced;
a means for engaging a force received in a middle portion of the means for supporting, the means for generating a force having a rotational end and an engagement end;
a means for releasing the means for engaging from the means for supporting coupled to the means for engaging to position the means for engaging along a length of the means for supporting the means for releasing configured to engage the means for engaging at an infinite amount of positions along the means for supporting; and
wherein the means for releasing includes a tab opening that receives the means for supporting and at least one of either a top portion or a bottom portion of the tab opening engages the means for supporting.

### Claim 8 (depends on 7)

The puller tool of claim 7, wherein the means for supporting further comprises alignment notches that are used to align the means for engaging so that they are evenly placed from each other means for supporting.

### Claim 9 (depends on 7)

The puller tool of claim 7, wherein the means for engaging include retaining tabs on an outside surface to retain a means for restraining.

### Claim 10 (depends on 7)

The puller tool of claim 7, wherein the engagement end includes a tapered pointed end to engage the component being serviced.

### Claim 11 (depends on 7)

The puller tool of claim 7, where in the foot includes a curved engagement portion.

### Claim 12

The puller tool for servicing a component, comprising:
a means for supporting;
a means for engaging a component being serviced that receives the means for supporting and is supported by the means for supporting and includes a foot at a lower end to engage the component being serviced;
a means for generating a force received in a middle portion of the means for supporting, the means for generating a force having a rotational end and an engagement end; and
a means for releasing the means for engaging from the means for supporting coupled to the means for engaging to position the means for engaging along a length of the means for supporting the means for releasing configured to engage the means for engaging at an infinite amount of positions along the means for supporting; and
wherein the means for releasing further comprises:
a tab portion;
a pin portion that extends from the means for engaging and engages the tab portion;
a spring means that biases the tab in an engaged position;
a middle portion that includes a tab opening portion that receives the means for supporting; and
a lower portion coupled to the means for engaging.

### Claim 13

A puller, comprising:
a cross bar;
a pair of puller legs where each leg receives the cross bar and includes a foot at a lower end of the leg to engage a component being serviced;
a screw received in a middle portion of the cross bar, the screw having a first end and second end; and
securing mechanism associated with each puller leg configured to selectively secure the puller leg from moving along a length of the cross bar away from the screw wherein the securing mechanism includes a hole in a tab that is at an angle with respect to the cross bar and the tab is configured to flex thereby changing the angle to either lock or unlock the crossbar with the puller legs.

### Claim 14 (depends on 13)

The puller of claim 13, wherein the puller legs include an opening dimensioned to be slightly larger than the cross-sectional area of the cross-bar.

### Claim 15 (depends on 14)

The puller of claim 14, wherein the securing mechanism has an opening dimensioned to be slightly larger than the cross-sectional area of the cross-bar and receives the cross-bar in the opening.

### Claim 16 (depends on 13)

The puller of claim 13, further comprising a hex head on one end of the screw configured to permit the screw to be turned by a tool.

### Claim 17 (depends on 13)

The puller of claim 13, wherein the securing mechanism contacts a side of the puller leg.

### Claim 18 (depends on 17)

The puller of claim 17, wherein the securing mechanism is located on a side opposite of the puller leg than a side facing the screw.

### Claim 19 (depends on 13)

The puller of claim 13, wherein the puller legs each have a shank section extending away from the cross bar and the foot includes a flat surface extending away from the shank section.

### Claim 20 (depends on 19)

The puller of claim 19, wherein the flat section extends away from the shank section at approximately a right angle.

### Claim 21 (depends on 19)

The puller of claim 19, wherein each foot is curved such that a round object if engaged by the feet and having the screw located at approximately a center of the round object, will have an outer circumference that is approximately curved about the same radius about which each foot is curved.

### Claim 22 (depends on 13)

The puller of claim 13, further including markings on the crossbar at regular spaced intervals.

### Claim 23 (depends on 13)

The puller of claim 13, wherein the securing mechanism includes a movable fastener part that selectively engages and disengages with the cross bar to selectively prevent and not prevent the puller legs to move along the crossbar away from the screw.
