How to Troubleshoot & Replace Whirlpool AP6020747 / WPW10388414 Drive Belt

Your site is amazing. I found the parts and the video I needed. Took less than 30 mins. 

Pull the washer away from the wall. Unplug it. Remove the lower back panel, just the star bolts that attach that panel. Visually inspect the problem. The belt was off and the drive pulley was wobbly. Because the bolt on the drive pully was tight and the pulley wobbled I decided I needed to replace it. The belt had some slight damage and could have been reinstalled but I decided to replace it. While holding the pulley turn the nut in the center. I used another wrench to block the pulley by inserting it into the slots on the machine. it was fairly easy to remove. The pulley replacement was easy and it fit tight to the shaft on the drum. The belt replacement was more difficult because it seemed to short but after comparing it to the old one I installed it. Put it over the small lower motor pulley lining up the notches in the belt and pulley and spin the drum pulley until it is fully around both. Be careful, it is a tight fit and I'm sure fingers could be damaged. I then replaced the back panel, plugged it in and put a large quilt in it as a test. It works well. 

First I went to the internet to get ideas as to what might be the problem then to you tube where I found your video's on changing out the belt and drive pulley which I found to be incredibly helpful. The video's gave me the confidence that I could make the repair myself. I then went to your website entered the model number and was amazed at the drawings of the inside of the washer with everything labeled. I chose my parts and they were delivered within two days. I followed the video's instructions and had the washer running in less than an hour. Thank You 

I replaced the 4 shock absorbers on the drum . I also replaced the drive belt because of its age and the machine was apart. 

Replaced the drive belt. Removed the back of the washer. Turned the drive wheel and forced the drive belt off the drive pulley. Put the new belt on the motor pulley and placed the belt on the drum pulley. It was much tighter then the old belt so it took a little more effort to turn the drum pulley and get the new belt over the drum pulley. Replaced the back and the repair was complete. About a 30 minute repair. All toll from time started to collect tools to finish 

Repl.aced the pulley and the drive belt. Washer had been making a knocking noise for a while. I should have known that it was a signal that something was not right. It looks like the bolt on the pulley worked loose and the pulley was hitting the tank and the belt finally jumped off the pulley. it got wrapped around the pulley and broke. I installed new part and was up and running in about 15 minutes. 

Did web search on changing the drive belt in front loader Whirpool washer. AppliancePartsPros.com had YouTube video showing in detail the belt remove/replace procedure. Ordered part from link on video, parted arrived at house before I could from my trip. 30 minutes later the belt was installed and squeak was gone. The video explained in detail the belt change. Made it easy.... 

Replaced both 

The video and explanations were very helpful. Assisted in diagnosing the problem and determining which part to order. Installation was easy with the video and could be done by most. 

Replaced all 4 shocks and the 2 springs holding the drum up. Also changed the belt while I had the rear of the machine off. Works great again!
