Old layabout
Mentioned doing this one a while back, so here goes.
Bottom bracket bearing replacement, inspired by RJ the Bike Guy over on the tube.
This particular BB was running as rough as, well, don't no what really.
The non drive side cup pops off easy enough, but the drive side need a few taps with the rubber persuader
The spindle is held firmly, and a lot of tapping needed to get the first bearing off. The spacer pushes out of the way enough for access.
Second bearing like so. Again, lots of tapping and it eventually gives way.
So here we are, all disassembled.
Here's the second bearing going on (sorry, forgot to photo the first one). A socket is used so as all the hammering is to the inner race.
I've not put the cups back on as you can see. On most BB's, one side of the spindle sticks out more than the other. This gives you two choices when deciding which side to have each cup, and so two different chain lines.
These are just unbranded bearings, so no idea of quality or longevity.
Most of my builds are done on the cheap, and often recycled into other projects, so nothing fancy needed.
That's it for this one, it'll go back in the BB tub, ready for a future project.
