Tire sensor grommet tool and method
View Patent ↗A tire pressure monitoring system (TPMS) sensor grommet tool has a U-shaped portion adapted to be inserted between a grommet disposed on the stem of a TPMS sensor and a seat at the base of the stem in which the grommet resides to separate the grommet from the seat for removal of the grommet from the TPMS sensor. The tool might also include an installation opening adapted to be disposed about the stem to guide and/or push a new grommet down the stem and into the seat. The leading edge of the tool, and/or and the U-shaped portion, may be beveled, to facilitate insertion of the U-shaped portion between the grommet and the seat. A flat side or ledge of the U-shaped portion may be adapted to separate the grommet from the seat, such as by levering against the seat to lift the grommet from the seat for removal.
1. An integral tire pressure monitoring system sensor grommet tool comprising a U-shaped portion adapted to be inserted between an existing grommet disposed on the stem of a tire pressure monitoring system sensor and a seat at the base of the stem in which the existing grommet resides to separate the existing grommet from the seat for removal of the existing grommet from the tire pressure monitoring system sensor.
2. The tool of claim 1 , further comprising an installation opening defined in the tool adapted to be disposed about the stem to guide a new grommet down the stem and into the seat.
3. The tool of claim 1 , wherein a leading edge of the tool is beveled to facilitate insertion of the U-shaped portion between the existing grommet and the seat.
4. The tool of claim 1 , wherein the U-shaped portion is beveled to facilitate insertion of the U-shaped portion between the existing grommet and the seat.
5. The tool of claim 4 , wherein a leading edge of the tool is beveled to facilitate insertion of the beveled edge of the U-shaped portion of the tool between the existing grommet and the seat.
6. The tool of claim 1 , wherein the U-shaped portion has a beveled edge and an opposite flat ledge, the beveled edge adapted to be inserted between the existing grommet and the seat, the flat ledge adapted to separate the existing grommet from the seat.
7. The tool of claim 6 , wherein the flat ledge is adapted to be levered against the seat to lift the existing grommet from the seat for removal.
8. A method comprising
inserting a U-shaped portion of a tire pressure monitoring system sensor grommet tool between an existing grommet disposed in a seat of tire pressure monitoring system sensor and the seat; and
lifting the existing grommet from the seat with the tool for removal of the grommet from the sensor.
9. The method of claim 8 wherein said lifting comprises levering the tool against the seat to lift the existing grommet from the seat.
10. The method of claim 8 wherein said lifting is carried out without interfering with or damaging the stem.
11. The method of claim 8 wherein said lifting is carried out without damaging threads defined on the stem.
12. The method of claim 8 further comprising:
disposing a new grommet on a stem of the tire pressure monitoring system sensor;
placing an installation opening defined by the tire pressure monitoring system sensor grommet tool about the stem; and
guiding the new grommet along the stem and inserting the new grommet into the seat using the tool, with the installation opening disposed about the stem.
13. A method comprising
inserting a U-shaped portion of a tire pressure monitoring system sensor grommet tool between an existing grommet disposed in a seat at the base of a stem of a tire pressure monitoring system sensor and the seat;
lifting the existing grommet from the seat;
removing the existing grommet from the stem;
disposing a new grommet on the stem;
placing an installation opening defined by the tire pressure monitoring system sensor grommet tool about the stem;
guiding the new grommet along the stem toward the seat using the tool with the installation opening disposed about the stem; and
inserting the new grommet into the seat using the tool, with the installation opening disposed about the stem.
14. The method of claim 13 wherein said lifting comprises levering the tool against the seat to lift the grommet from the seat.
15. The method of claim 13 wherein said lifting, guiding and inserting are carried out without interfering with or damaging the stem.
16. The method of claim 13 wherein said lifting, guiding and inserting are carried out without damaging threads defined on the stem.
