There could be a number of answers for this problem. 1- are all of your pulleys in line. 2- has someone tried to turn one or more of he pulleys with a pair of pliers of pipe wrench and left burrs on the pulleys. 3- do you have bad bearing in one of the idler or the tension pulleys which could be making that pulley tip forward.
