try loosing the WOD at the end of the model number, you will have better results looking for parts.

Well, I got the belt and put it on.  It did change the location of the idler pulley in relation to the drum.  I also replaced both rollers, the idler pulley, the front felt bearing and the rear felt seal.

Now it goes kabump kabump....kabump kabump...kabump kabump, as the drum turns.  I looked under there while it was running and notices that the idler pulley is falling into the scallops in the drum as they pass by each revoluton and then bumping the other side of the scallop each time which causes the noise. 

That makes me think that something is still wrong because it causes more noise than I would expect form a dryer.  It can be heard from he next room.

Look along the backside of the drum for an object down in the groove that the rollers run in. Remove that object and the thumping will stop. Also make sure the felt is not running in the track.

The belt number I get is a 337388. That would make the difference.

Thanks JW, I looked in the grove and followed it for a full rotation.  The groove is clear.  Looked again at idler pulley.  It is bobbing up and down as the scallops go by.  It is falling into each scallop and then bumping the other side of the scallop.  This causes a tom tom noise. Two beats per revolution of the drum.
 
Thanks. the oldstoveguy.  I have used two belts.  One 92" long replacement for 341241and one 94 1/8" long 337019.  What is the 337388?

Is it possible to get the wrong idler pulley assy.  The new one I got looks almost like the old one.

Match them length wise, old belt to new. I put in that model # and came up with the other belt part #, different length. That would make the idler run as you said.

Thanks oldstoveguy.

What part number did you get when you put in that model number?

If you go to SEARS site, look under parts. Put in model but leave off the OD on the end of your model number, you can see all of the parts for that dryer and part numbers. That was made by Whirlpool so can go back to any parts site and use the Whirlpool part number which is part number 337388. The 337019 is a different length.
