Hi, great post! I've got a DE90 with the same setup. Ive got two questions about the middle of the tensioner pulley:
1. Should the rotation happen between the pulley and the OD of the brass sleeve bearing, or between the ID of the brass sleeve bearing and the steel post that's attached to the slide? My machine was making an ear piercing squeak, and the OD of the sleeve bearing (the non flange end) shows wear from rubbing on the ID of the pulley (which also shows some wear and a couple burrs/shavings). A whole bunch of black powder appeared under this during the squeakville era. (super fine metal shavings? graphite?) Which leads to the second question:
2. There's a natural fiber string wound around the brass sleeve bearing. The center of parts of it looks like it was white originally, but externally it is all very black. Mine has been broken into a couple lengths. My best guess... is this string covered in graphite to lubricate the steel post via the slot in the sleeve bearing? Or was the string covered in oil, like the descriptions on this site Ive seen of the felt on the drum support bearing? Mine doesn't seem oily. The steel post however has some seriously dried up black gunk on it - maybe old oil (and possibly graphite?) or just dirt. I looked into getting a new flanged sleeve bearing but can't find one the right size. Im hoping its not too far gone. Thank you for any insight!

Maytag halo of heat, speed, reduction, pulley, and bearing

Hi, you need another pulley and bearing assembly. The bearing was permanently pressed into the pulley your bearing seized up on the steel shaft, and then destroyed the pulley. It might be possible if you have a good machinist to drill out the pulley and to make a custom bearing to make this work.

The black stringy stuff looks like an old belt to me. There was nothing like that used although it might be some of the wicking that was outside the bearing inside the pulley that you’re seeing there was no graphite of any type used with this set up. it was just a bronze bushing that was permeated with oil when it was manufactured. It was meant to be oiled occasionally every 10 or 20 years to keep it turning smoothly on the steel shaft.

I have good use pulley and shaft assembly. If you want I’ll sell you one for 50 bucks plus shipping. I just recycled DE90 a few months ago, but all of Maytag dryers use the same set up from the late 50s till the mid 70s

Oh wow, the bearing was permanently pressed in there...that's why its not on the part list! Then that string must be original. Its definitely a yarn, doesn't seem belt-like, carefully wrapped around the middle 1/3 of the bearing. There is space built in for it since the bearing only contacts the pulley on the ends. The slit in that non-contact-middle-zone of the bearing points toward it being a cotton wicking for oil transfer, the slit is about 1/2" inch long and 1/16" wide running parallel to the flange. I guess you'd have to re-oil through that slit if that bearing is permanently installed. (Only other scenario I could think of is this was someones previous repair because this wear actually happened years ago - maybe as a compression packing to jam the worn bearing back in there? but the way it was carefully wound and the built in space for it makes me lean toward oil)
Either way - thank you for your advice, it confirms what I was thinking, and thanks for your offer of the pulley/shaft. I'll think this over and pm you if I decide I want to follow through!
 
I always use grease on the speed reduction pulley shaft as opposed to oil since oil has a tendency to go MIA in that particular application. So far, never had a problem with that in my 7 going on 8 years experience with the Maytag HOH’s.

Believe the bearings on Maytag HOH’s are Oilite bearings which are sintered bronze bearings.
 
The bearing won't likely have worn to a loose fit, but the pulley will. If not, and if the bearing is shot, it's sometimes possible to press in a new one. Most ball bearings have a standard number on them that can be cross referenced to multiple manufacturers if it's not available OEM.
