Never ever pry off the seal from the inner race. Use the pick adjacent to the outer race. The nitrile or neoprene seal will be in contact with the rotating inner race and sealing it. Any imperfection in the seal will destroy the bearing. The outer race is stationary relative to the nitrile or neoprene seal, and hence pry off from the outer edge adjacent to the outer race of the bearing. This advice is for those seals which are in contact with the rotating inner race of the bearing.
With all the non-flammable options that actually do an as good or better job de-greasing anyway, and the fact that they will not degrade most of the typical plastic or elastomeric materials in some bearing (cages, seals, etc..), it seems like a win-win to use other friendlier solvents. But still DO make sure it's in a ventilated space. Thanks for watching, and for your comments!
I'd say that CRC owes you a new can of brake cleaner, since most of what you used, leaked past the spray valve and ran down the side of the can........
The nice thing about greasing your own bearings is that you can decide what grease to put in based on the service requirements. Wheel bearing grease would be fine for some types of service (such as wheels, lol), but you can pick the bearing grease based on the type of perils that your device may be subjected to. Need more heat resistance? Need something that can operate submerged? High RPM? Extremely cold duty? Pick the type that is optimal for your type of use. Good luck, and thanks for watching!
To be honest, I've heard of it, but have no data at my fingertips on what works, doesn't work, or recommended combinations that are proven winners. Like most lubrication scenarios, it will be application-specific as to what combinations are most effective. Google will have to be your friend on this one ;) Thanks for watching!

Good to know, and thanks for watching and commenting!
Spot on, as was said use a paraffin based solvent to dissolve the grease initially . Alcohol's and ketones don't work as well.

Great info on the bearings, Have you ever replaced the bearings on the spindles on your 54" deck ?
Thanks! No, not yet, but when and if I do, I'll make a vid of that process as well. Thanks for watching!

Lol, you saw that, huh? Yeah, but got it done nonetheless... Thanks for the laugh, and for watching!
Great video, thank you
Glad you liked it, and thanks for watching!
Is wheel bearing grease a good option for regreasing these?

Can you add PTFE or Graphite powder to bearing grease?

@@halfmoontechlabs You're welcome. I'm thinking primarily of loose cup and cone bicycle bearings.
