The common problem encountered when inspecting a Rubber V Belt is to wear a lid on the back of the belt. It is belts rubbing on the guard, the belt is prying, the wrong thing to relax or the back idler. You can track the belt by winding the pulley around the belt to determine if the belt is rubbing against the belt guard. For the belt was forced open, look at the belt installation. If the tension is too large, it may cause the belt to hit the belt guard, usually not encountered. One of the most overlooked reasons is the back idling pulley. Normally, the bearings in the pulley will become frozen and cause the belt to slide on the pulley. This can cause additional pressure on the belt and may cause the belt to fail or prematurely wear.

When checking their V belts, another common problem people encounter is the belt flipping. The belt can be turned in the pulley, there are many different reasons. This may be caused by problems in the machine or improperly installed by the operator. When trying to determine what causes the belt to rotate, start from the belt. Most of the reasons can be confirmed by replacing the belt with the manufacturer's belt number and confirming that the belt is installed correctly. The belt does not need to be pryed, the correct belt type and cross section, and the belt need to be tightened by the manufacturer's specifications. If the belt is still loose, then you may have changed the wrong belt.

If you change the belt and find that the belt is still flipping, move to the machine to see if there is a problem with the pulley. To see if the pulley is aligned, you can place the belt in the groove to see if there is a bend, or place a flat edge along the side wall of the pulley and make sure they are straight. The last step is to make sure that the bearings on each pulley are still good. If the bearing is not good, the pulley can not be aligned.
