Wheel bearing disassembly question

aparchment · #1 02-15-2014, 02:55 PM

Is there an easy way to take the wheel bearing itself apart? I got some metal shavings on it and want to completely disassemble it for cleaning.

I have the bearings out of the wheel hub now I need to get the race (I think it's called) separated from the metal part that surrounds the axel. There must be some trick to move the cylindrical rollers out of the way so that the part that rides on the axel can slide by.

The tapered roller bearing consists of a 'Cone" and a "Cup".
i.e. inner and outer races. The outer race is a press fit in the wheel.

The inner race or "cone" has the race, roller separator and rollers.
These are not disassembled in the field. Or anywhere else for that matter

So, to clean it just slosh it around in mineral spirits.
Don't spin it with compressed air as you could damage it.

Hope this helps,
Mark

If you have metal shavings in the wheel bearing it is time to buy new bearings and replace them, repack with good wheel bearing grease and reinstall, go flying and enjoy.

Don't forget to get a brass drift pin and drive out the old race and replace it also.You can use the old race as a driver over the new race and a block of wood to bang on.
