Toothed belt installation tool

1. An installation tool for installing a toothed belt, the installation tool comprising:

a main body;

a first arm extending away from the main body, the first arm comprising a first engagement surface;

a second arm extending away from the main body, the second arm comprising a second engagement surface; and

a stop positioned between the first and second arms;

wherein the first arm is configured to be inserted into a first opening of a housing and the second arm is configured to be inserted into a second opening of a housing; and

wherein the stop is configured to contact a surface of the housing to stop advancement of the first arm within the first opening and the second arm within the second opening such that the first engagement surface and second engagement surface are positioned at depths within the first opening and second opening to guide a toothed belt inserted into the housing.

2. The installation tool of claim 1 , wherein the first and second engagement surfaces are curved.

3. The installation tool of claim 1 , wherein the first engagement surface and the second engagement surface face each other.

4. The installation tool of claim 1 , wherein the first and second arms are positioned at depths within the first and second openings to prevent a toothed belt inserted into the housing from extending into the first or second opening.

5. The installation tool of claim 1 , comprising a first contoured portion extending between the first arm and the stop and a second contoured portion extending between the second arm and the stop.

6. The installation tool of claim 5 , wherein the first contoured portion and second contoured portion each comprise two opposing curves.

7. The installation tool of claim 1 , wherein the first arm and second arm are on opposing sides of the main body.

8. The installation tool of claim 1 , wherein the first engagement surface and second engagement surface are shaped to direct the toothed belt toward a sprocket within the housing during installation of the toothed belt.

9. The installation tool of claim 1 , wherein the first engagement surface is disposed on an inside surface of the first arm and the second engagement surface is disposed on an inside surface of the second arm.

10. The installation tool of claim 1 , wherein the first engagement surface is disposed at an end portion of the first arm and the second engagement surface is disposed at an end portion of the second arm.

11. The installation tool of claim 1 , wherein the first arm further comprises a flat end and the second arm further comprises a flat end.

12. The installation tool of claim 1 , wherein the installation tool is made of aluminum.

13. An installation tool for installing a toothed belt, the installation tool comprising:

a grasping portion;

a first arm extending away from the grasping portion, the first arm comprising a first curved surface;

a second arm extending away from the grasping portion, the second arm comprising a second curved surface; and

a stop positioned between the first and second arms;

wherein the first arm is configured to be inserted into a first opening of a housing and the second arm is configured to be inserted into a second opening of the housing; and

wherein the stop is configured to contact the housing to position the first arm into the first opening and the second arm into the second opening at depths such that the first curved surface and second curved surface are radially offset from a sprocket housed within the housing, wherein the first curved surface and/or second curved surface are configured to guide an end of a toothed belt inserted into the housing for installation around the sprocket.

14. The installation tool of claim 13 , wherein the first and second curved surfaces are configured to impede the toothed belt from being inserted into the first opening and second opening.

15. The installation tool of claim 13 , wherein the first arm is in a mirrored configuration relative to the second arm.

16. The installation tool of any of claim 13 , wherein the stop is disposed between the first arm and the second arm.

17. The installation tool of any of claim 13 , wherein the first curved surface is disposed at an end portion of the first arm and the second curved surface is disposed at an end portion of the second arm.

18. A method of installing a toothed belt on a sprocket within a housing, the method comprising:

aligning a first arm of an insertion tool with a first opening of a housing;

aligning a second arm of the insertion tool with a second opening of the housing;

advancing the first arm into the first opening and the second arm into the second opening until a stop of the insertion tool contacts the housing to prevent further advancement such that a first engagement surface of the first arm blocks access to the first opening from within the housing and a second engagement surface of the second arm blocks access to the second opening from within the housing;

advancing an end of a toothed belt into a first channel of the housing; and

rotating a sprocket disposed within the housing until the sprocket engages and drives the toothed belt through the housing and out a second channel of the housing.

19. The method of claim 18 , further comprising deflecting the end of the toothed belt off the first engagement surface and toward the sprocket.

20. The method of claim 18 , wherein aligning the first arm of the insertion tool with the first opening of the housing comprises orienting a center longitudinal axis of the first arm to be coaxial with a center axis of the first opening and aligning the second arm of the insertion tool with the second opening of the housing comprises orienting a center longitudinal axis of the second arm to be coaxial with a center axis of the second opening.
