After taking the Cat MTL training school, it was instructed for us to set track tensions at 1/2". we did this using a 100# weight in the center top of the track, and placing a straight edge on the front roller and drive sprocket, then measuring the distance. We began to get a slight popping in our track, a sign that perhaps the tracks are too loose. I called the service manager of our dealer, who left his office that afternoon to check the machine out. We determined that the tracks should really be set with 1/4" gap instead of 1/2". The popping stopped. Has anyone who has taken MTL school had this similar problem with thier machine? And, if you did, what did you do to correct it?
