Question about Idler Pulley
I am in the process of replacing a dryer belt on a 29" Whirlpool dryer. The diagram is very helpful, but I do have a question about the idler pulley. Is the idler pulley supposed to lock down into the bottom of the machine, or is the front lip on the bottom just supposed to go into the bottom of the machine and then tension on the belt keeps the pulley in place? The model of dryer I am working on is an LG5811XP, if that makes any difference. Thanks very much for your help.
