First I want to mention the videos on your website were helpful in detailing the order and procedure in which to disassemble and put the dryer back together. I had to replace the motor which was making a lot of noise and then the dryer stopped running altogether. I strongly recommend replaceing the belt tension pully as these tend to wear more than other parts. Also replaced were the drum support rollers and the dryer belt. IMPORTANT, in order to remove the motor I had to remove the blower wheel. Simple enough but, the 7/8 nut holding it on to the motor would not loosen. I used a 6 point socket but it kept slipping off. The blower wheel is made of some kind of nylon compound (?). The nut itself is moulded around a metal sleeve threaded on the inside to screw onto the motor. Apparently this sleeve was siezed to the motor. I contacted AppliancePartsPros.com and it was suggested to chisel the wheel off. I had to remove the entire assembly from the dryer including the motor mount, not a big deal. Using a wood chisel I was able to get the wheel off without much of a problem but had to be careful not to damage the blower housing because it's my understanding they're no longer available. Of course I had to puchase a new blower wheel. I appreciate the advice given by AppliancePartsPros.com and now the dryer is up and running. I gave it a difficulty of 4 only because of the blower wheel. Other than that it's not a complicated fix at all.
