Abstract

An engine pulley testing device for detecting damaged engine pulleys featuring a first support arm and a second support arm pivotally connected via a pivot component. Lengths of the support arms are adjustable. A brace component connects the support arms and functions to temporarily secure the support arms a certain distance apart. A pulley pole extends through the pivot component such that the first support arm and second support arm pivot about the pulley pole via the pivot component. A top pulley is disposed on the pulley pole, a first bottom pulley is rotatably attached to the first support arm, and a second bottom pulley is rotatably attached to the second support arm. An engine belt can be wrapped around the first bottom pulley, the second bottom pulley, the top pulley, and a test pulley being tested in an engine.
