Abstract

An engine pulley testing device comprising a first support arm pivotally connected to a second support arm; an arc-shaped brace component with a slot disposed therein, wherein the brace component is slidably attached to the back of the first support arm and the back of the second support arm, wherein the brace component can be locked to the first support arm and to the second support arm via a third locking means; a third support arm attached to the support brace and extending upwardly past the pivot component; a pulley pole perpendicularly attached to the third support arm; and a top pulley attached to the pulley pole, a first bottom pulley rotatably attached to the first support arm, and a second bottom pulley rotatably attached to the second support arm; wherein an engine belt can be wrapped around the pulleys and the test pulley being tested in the engine.

Claims

1. An engine pulley testing device for testing a test pulley in an engine, said engine pulley testing device comprising:

(a) an adjustable first support arm and an adjustable second support arm, wherein a first end of the first support arm is pivotally attached to a first end of the second support arm via a pivot component;

(c) an arc-shaped brace component for securing the first support arm and the second support arm a particular distance apart, wherein the brace component has a first end, a second end, and a third slot disposed therein, wherein the third slot extends from near the first end of the brace component to near the second end of the brace component and from a front surface of the brace component through to a back surface of the brace component;

wherein the brace component is slidably attached to a back surface of the first support arm via a third screw disposed on the first support arm and extending through the third slot, wherein the brace component is slidably attached to a back surface of the second support arm via a fourth screw disposed on the second support arm and extending through the third slot, wherein the brace component can be locked to the first support arm and to the second support arm via a third locking means;

(d) a third support arm having a first end and a second end, the first end being attached to the support brace and the second end extending upwardly past the pivot component, wherein a pulley pole is perpendicularly attached to the second end of the third support arm; and

(e) a top pulley attached to the pulley pole, a first bottom pulley rotatably attached to a front surface of the first support arm, and a second bottom pulley rotatably attached to a front surface of the second support arm;

wherein an engine belt can be wrapped around the first bottom pulley, the second bottom pulley, the top pulley, and the test pulley being tested in the engine.

2. The engine pulley testing device of claim 1, wherein the adjustable first support arm comprises a first inner post telescopically received in a first outer post, wherein the first inner post can be locked in the first outer post via a first locking mechanism.

3. The engine pulley testing device of claim 1, wherein the adjustable second support arm comprises a second inner post telescopically received in a second outer post, wherein the second inner post can be locked in the second outer post via a second locking mechanism.

4. The engine pulley testing device of claim 2, wherein the first locking mechanism comprises a first screw disposed on a front surface of the first inner post and extending forwardly through a first slot disposed on a front surface of the first outer post;

and a first lock nut attached to the first screw externally to the first outer post, wherein the first lock nut can be turned to lock the first inner post to the first outer post.

5. The engine pulley testing device of claim 3, wherein the second locking mechanism comprises a second screw disposed on a front surface of the second inner post and extending forwardly through a second slot disposed on a front surface of the second outer post;

and a second lock nut attached to the second screw externally to the first outer post, wherein the second lock nut can be turned to lock the second inner post to the second outer post.

6. The engine pulley testing device of claim 1, wherein the pivot component is a hinge or a pivot screw.

7. The engine pulley testing device of claim 1, wherein a power motor component is disposed on a second end of the third support arm for rotating the pulley pole and top pulley.

8. The engine pulley testing device of claim 7, wherein the power motor component is operatively connected to a power source.

9. The engine pulley testing device of claim 1 further comprising a gripping component disposed on a second end of the first inner post and on a second end of the second inner post to help stabilize the engine pulley testing device when in use.
