Abstract
A faucet valve cartridge pulling tool comprising a housing, a stem screw, and a collar. The housing has a first end and a second end. The first end has a surface adapted to abut a portion of a faucet valve body. The stem screw has a first end and a second end. The stem screw includes a first threaded section and a second threaded section. The first threaded section is adapted to engage internal threading of a faucet valve cartridge stem located within the faucet valve body. The collar has 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.
Claims16
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.
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.
