Upon examination of the dryer, I noticed that the belt was intact, though a little worn and hard. However, I noticed that the belt had came of the idler pulley. So I put it back on and had the owners try it out on their next load of wash. It, once again failed to keep the drum turning. So I ordered a new belt and idler pulley (order # 8676164). I found it necessary to remove the drum, in order to change out the new pulley. However, while trying to reinstall the drum, we damaged some of the insulator mounting plates, which were very brittle, which caused the heater element coils to rub against the drum. I then ordered a heater element kit, 2 bearing slides , dryer drum front support bearing, and lint screen housing seal, and a screw ( order # 8707123). The repair was divided into two different sessions. One to unhook, and remove the heater element assembly, and remove the old heat coils. During that time, we changed out the dryer drum front support bearing, and installed 2 of the 4 needed bearing slides. I realized that there were two more of the bearing slides needed which had a different part number. I strongly feel that the four bearing slides should be included and already installed on the drum front bearing support. Now for the installation of the heat elements and insulators. I was glad that I still had enough serviceable existing insulator mounting plates to go with the new ones included in the element kit, as the kit does not include the full amount needed to replace all of them. It took me a good hour to install the plates, and string the heat element coils, and another 45 minutes to an hour to reassemble the dryer. In hind sight, I feel it would be well worth it, to spend the extra $70.00 to purchase a fully assembled heater element assembly. It will cut the repair time in half, and remove a lot of margin for error, during the installation of the heat element coils onto the element mounting plate. However, at this writing, the repair was a success. The dryer is once again in operation, alleviating the need for a clothesline. I did have to order 2 more bearing slides to complete the amount needed on the drum front support bearing.
