Re: Premature Bearing Failure
It’s only the 30mm WMA seal that does that, the 35mm is a standard all be it very deep seal. I always grease the gap in the back and the seal lip. A smear on the shaft as well.
Re: Premature Bearing Failure
The old Hotpoint drum supports on the Wm series etc used to use a phosphor bronze collar which helped lubricate the bearing seal, but they found with the new detergents drew the the lubricationg oils out the collar and allowed a path for water to get past the seal, they then changed to to stainless and then brass, down side was that sometimes caused them to squeak especialy on the washer dryers i always put a smear of grease on the collar when i changed bearings and support as there was a good chance you would get a recall for squeaking.

@madangler1
On the 35mm seal the outer metal ring does revolve in relation to the rest of the seal and there is a layer of grease between them. You can pop the central part out of the metal outer quite easily (and back in again!) and you’ll see it has a system of lips which engage it over the metal outer. Why would they put grease in there if it wasn’t intended to move? And why would it have a similar inner surface to the 30mm seal which you agree does what I said?
I agree it seems too stiff to turn but who knows what happens when it’s installed and things are warmed up and travelling at speed?
I think it may be that it is held firmly between the inner race of the front bearing and the back of the spider when you tighten up the pulley bolt. And, if I’m right, this makes it more critical than ever that you get the outer ring exactly squarely in the housing.
