Core pulling tool

1. A faucet valve cartridge pulling tool comprising:

a tubular housing having a first end and a second end, the first end having a surface adapted to abut a portion of a faucet valve body;

a stem screw having a first end and a second end, the stem screw including a first threaded section and a second threaded section, the first threaded section adapted to engage internal threading of a faucet valve cartridge stem located within the faucet valve body;

a collar having internal threading engaging the second threaded section of the stem screw, wherein rotating the collar relative to the stem screw pulls the first threaded portion axially towards the second end of the housing; and

a flange extending radially outward from the second threaded section of the stem screw, the flange having an outer diameter less than a diameter of an inner surface of the tubular body.

2. The faucet valve cartridge pulling tool of claim 1 wherein the housing further having an annular end plate at the second end, the annular end plate defining a hole, the stem screw located in the hole of the annular end plate.

3. The faucet valve cartridge pulling tool of claim 2 wherein the collar applies a force against the annular end plate of the housing upon rotating the collar relative to the stem screw.

4. The faucet valve cartridge pulling tool of claim 1 wherein the stem screw further having a handle extending radially outward.

5. The faucet valve cartridge pulling tool of claim 1 wherein the stem screw further having a hexagon shaped expansion at the second end.

6. The faucet valve cartridge pulling tool of claim 1 wherein the collar further having a handle extending radially outward.

7. The faucet valve cartridge pulling tool of claim 1 wherein the collar having a hexagon shaped outer surface.

8. The faucet valve cartridge pulling tool of claim 1 wherein the tubular body includes a window.

9. The faucet valve cartridge pulling tool of claim 1 wherein the housing further having a sleeve radially inward of the tubular body, the sleeve defining a bore extending axially through the sleeve, the stem screw located in the bore of the sleeve.

10. The faucet valve cartridge pulling tool of claim 1 wherein the stem screw defines a groove, the flange situated radially outward of the groove.

11. The faucet valve cartridge pulling tool of claim 10 wherein the flange is an E-clip.

12. The faucet valve cartridge pulling tool of claim 1 wherein the housing further having a cap attached to the tubular body.

13. The faucet valve cartridge pulling tool of claim 12 wherein the cap includes internal threading for attaching the cap to the tubular body.

14. The faucet valve cartridge pulling tool of claim 1 further comprising a washer axially between the housing and the collar.

15. The faucet valve cartridge pulling tool of claim 1 wherein the stem screw further includes a conical section between the first threaded section and the second threaded section.

16. A method for pulling a faucet valve cartridge comprising the steps of:

providing a housing having a first end and a second end, the first end having a surface;

providing a stem screw having a first end a second end, the stem screw includes a first threaded section and a second threaded section;

providing a collar having internal threading engaging the second threaded section of the stem screw;

positioning the first end of stem screw in an opening of a cartridge stem located within a faucet valve body tube having a surface;

rotating the stem screw to insert the first threaded section of the stem screw within the cartridge stem;

positioning the surface of the housing in abutting relationship with the surface of the faucet valve body tube; and

rotating the collarrelative to the stems crew to pull the cartridge stem towards the second end of the housing;

wherein the housing further having an annular plate at the second end, the step of rotating the collar relative to the stem causes the collar to apply a force against the annular plate and the stem screw further having a conical section between the first threaded section and the second threaded section, the step of rotating the stem screw to insert the first threaded section of the stem screw within the cartridge stem continues until the cartridge stem contacts the conical section of the stem screw.
