How to change grease on sealed bearings?

<< < (2/3) > >>

awemawson:
Here you go, looks easy enough:

I have done this very frequently over the last thirty years. I discover how little grease there were in bearings with seals when I worked with an auto electrician in Toulouse. My colleague systematically took the seal of alternator bearings and repacked them.

Never had any trouble doing this!

RS sealings come out and are easily pressed back easy too. However I only had good degree of success on low rpm application. Whenever I tried this to low friction type seal it did not work that well. They look the same than RS seal, but often are harder material and they should nor rub. Bit like plastic version of Z (dust seal). Got some one sided RS and Z bearing on last batch, have some time to experiment.

The 2RS seals on my bike bearings come out no probs for a quick flush and a squirt of new grease. I use a scalpel to pop them out but they are only small-ish ones like 6000, 6001.

Have you checked if you can get brand new replacement seals? You might have better luck getting a new one back into place.
