I have replaced the rollers, gliders, and a new belt. When I put the machine back together it seems like it is off centered and has a hard thump on every rotation. When I had the machine apart, I was looking at the idler pulley and it was only solid about half way around. Half of the pulley belt surface area is close to outside diameter of the pulley. The other half drops down inside the pulley close to the center. Is this normal? Should I buy another idler pulley?

After the drum on the dryer stopped turning (motor seemed fine), I assumed the belt broke. After taking apart the dryer, the old belt was not broken, but kind of strenched and worn. I replaced the belt, but it slips off the tension wheel as soon as I start the dryer. The wheel is wobbly, loose on its axle. Is this normal or did I put the new belt on wrong? Any help is appreciated. Thanks,

The belt tension pulley is screeching. Should I try replacing just the pulley itself first and not the whole assembly? Is there a bearing on the pulley wheel that usually causes this noise? I figure the arm, shaft, washers, retaining ring can be reused if a bad pulley bearing is the problem?

Latest Questions

Same problem as before except now the dryer shuts off after 30 minutes. I tried a different timer and that didn't cure it either. Could there be a thermal overload in the motor thats causing this? Does that mean replace the motor?

I Replaced the pulley tensioner assembly and belt on the dryer. Now the dryer seems to start hard - like a power tool without soft start - and there is a 'hard' motor noise. Could this be the bearing on the motor? Any suggestions? Thanks for any help!!

I have ordered this part and also the belt part # AP4049271. The pulley seems to be to wide for the belt. Is it supposed to be this way?
