How to Troubleshoot & Replace Speedqueen AP6285125 / D510185 Spring Idler

After watching a video and calling appliance parts pros, I replaced the belt. 

Replaced the spring, retaining ring and the pulley itself. 

Put the new spring and belt on. Fit perfectly correct part. Fast shipping got here in three days. We have an Amana dryer and they're not the easiest to take apart and put back together but we managed with lots of videos 

MULTIPLE ITEMS REPLACED DUE TO WEAR. REPLACED, IDLER PULLEY, BELT, TENSION SPRING, FRONT FELT SEAL, REAR DRUM SUPPORT ROLLERS AND DRUM GUIDES. THIS DRYER HAD TO COME APART FROM THE BOTTOM UP, LOWER PANEL, THEN UPPER PANEL, MULTIPLE HEX HEAD SCREWS, ALL THE SAME SIZE, BELT WAS NOT EASY TO GET BACK ON, HAD TO RELIEVE THE TENSION ON THE IDLER BEFORE REINSTALLING THE BELT, MANAGED TO WEDGE A TOOL BETWEEN THE DRUM AND THE IDLER TO RELIEVE THE TENSION, THEN INSTALL THE BELT, NOT AN EASY TASK WHEN YOU CAN'T SEE WHAT YOUR DOING. THEN REVERSE ASSEMBLY THE REST, I WAS ABLE TO REMOVE AND WASH OUT THE DRYER DUCT ASSEMBLY, THREE SCREWS INSIDE THE DRUM AREA WHERE THE LINT FILTER IS, WAS FULL OF LINT, BE AWARE, SHARP EDGES EVERYWHERE, DRYER DRYS CLOTHES A LOT BETTER AND FASTER NOW. EVERYTHING TOOK ABOUT 4 HRS. 

I took the dryer apart, found the problem and ordered parts from appliancepartspros.com and they were the exact parts at a good price. Fixed dryer for my friend. 

Replaced idler pulley assembly and installed a new drum belt while I had the dryer apart. Everything is quiet and heating well.
