Front wheel bearing wadding

I've noticed that one of my front wheel bearings has lost the packing material (soft sort of fabric thing) that sits innermost between the hub and upright. Is it available separately? Bearing itself seems fine, and it's only happened recently so I don't really want to buy a whole new bearing kit just to get that bit. 1997 K-series if it makes any difference.

thanks,

 

Jon

Redline might have some in stock still. Make sure no sharp bits on casting, as it can peel the felt off like a potato peeler !

Felt seals, pre-lubricated and installed correctly are extremely tolerant of dirty environments that would wreck a lip seal in minutes.  They still have a use in all sorts of places.

You might want to buy three though, if you are doing both - then when you wreck the first one learning out to get the damn thing in, still in a usuable condition, you can still replace both hubs - and it you do make it without wrecking one, then you have a spare for next time.

Wherever I've bought them from over the last 20 years (use them on my trials car too), they don't seem to make them like they used to, hence the sometime easy peeling off of the felt.

Just remembering back to when I had these felt seals .... you have to get the metal cup in square. If you try to do it gently, a bit at a time, I remember it getting very bent very easily. I was shown the best way is to lay the hub with the studs face down on a bit of wood. Lay the felt seal on the bore it is going in to, metal side down. Put a flat piece of wood over the seal felt and hit the middle of this bit of wood hard with a big hammer to knock it home in one hit. I have to say I much prefer the new bearings with rubber lip seals.

Thanks. It's only one side that needs doing, and I've ordered two, so hopefully can get a good one in place.

What's the best lubrication - engine oil? Or something lighter? (not sure what I've got in the garage). The other thread suggests not using bearing grease as it's too sticky.
