How to Troubleshoot & Replace Whirlpool AP6022517 / WPW10512946 Dryer Drum Support Wheel Retainer

At first I tried lubricating the Idler Pulley which only lasted for about a day or two then I opted for replacing the Idler Pulley, four roller wheels, belt - much better results. Thanks appliancepartspro.com! 

Access to the idler pulley was accomplished by lifting the top deck, removal of the door and front panel. Next I released the drive belt from the idler pulley. Then removed the tension spring with needle nose pliers and the cap screw holding the idler pulley assembly. Re-assemble in reverse order with the new idler pulley. Very simple. About a 25 minute repair. Tip: several examples of this repair can be found on YouTube. Note: Only the idler pulley was used for this repair. I ordered the drum support rollers and tri-ring to have on hand. 

Replaced the roller, shaft, rings and washer. After removing the back, reverse threading the nut off, discarding the old hardware and installing the new hardware back in business in about 20 minutes. 

Followed the video- opened the front of the dryer and removed the drum. It was evident that one of the wheels had worn and wasn't turning freely like the other one. The video showed how to remove the roller. Very simple process and now the dryer works just fine. 

Got my dryer fixed in 2 hours with a Dryer Repair Kit and help from AppliancePartsPros.com's excellent YouTube video. The prices were great, shipping was fast and return of unused parts was hassle-free (I ordered front and rear support shafts in case the originals were scored but didn't need them.). I look forward to doing business with them in the future. 

Replaced idler pulley (which had seized), all 4 drum rollers with clips and replaced the belt- all in 45 minutes, start to finish. Your diagrams and videos were extremely helpful in the troubleshooting and ordering processes. Delivered in 2 days! Thank you! 

Using You Tube How-To Videos. Replaced the drum drive belt and tensioner pulley/arm (including) the spring. 

After shopping for a new Whirlpool Thin Twin Stack, Found appliance parts pros online and decided to take it apart to see if repair was a possibility. APPro's online instructions were easy to follow, in a couple hours it was apart, and I placed the order. Reg ground took a week from NY, so the laundry piled up that week. The parts arrived on Monday morrning, by afternoon the machine was running like new! The cause was the belt tensioner pulley had frozen. Replaced it, drum wheels,snap rings,drum belt. New cogs and seals for the Washing machine agitator were easy to replace and all worked great. $160 with shipping, saved us $1300 for a new machine. Also disabled annoying loud endcycle buzzer. Thanks APPro;s. we'll be back! Orig 1991 model.
