Most people say that the disadvantage of sealed bearing is that it is disposable. And so I thought until I read an article or YT re sealed bearings. Unless there is a wobble or looseness in the hub or concerned bearing, I think this operation is possible to save the bearing.
It happened that two bikes both rb developed whining and other sounds at the rear hub. Naturally the bearings are suspect. One had two 6802 bearings and I was able to buy only one (the last remaining unit) at P200.00 . However this were available at Lazada for only P200.00 for ten. Sayang.
The other bike hub had grating sound when free wheeling. Naturally the bearing is suspect
I did not have to have the bearing removed nor replaced. This post simply followed the advice.
1. Pry off the red or blue seal cover (with the bearing installed)with a sharp pointed cutter.
2. When the bearing becomes visible inspect for grit or rust. Spray WD 40 or other solvent to remove rust and grit.
3. Put low density grease or even oil for chain to have lube inside the bearing.
4. Reinstall the seals.
For me the grating sound and rough rotation were solved by this operation.
