Initially I took a vacuum hose and tapered tool to the area beneath the rotating drum and removed the lint. I figured that the lint accumulation was caused by some blowby the felts. Also I illuminated the belt and saw multiple splits in it. I found a source online for 4 wheels, an idler wheel , clips and the proper belt for my 27 " wide Kenmore/Whirlpool gas dryer. The video online was very thorough about the felt removal and prep for the replacements. I needed 2 sets of hands to fasten the felting properly. We allowed the curing process to proceed overnite and finished the project the next day. We certainly saved money repairing our old unit over purchasing a new unit. It's running like new.
