So I'm planning to overhaul the rest of my bike in the next weeks, but for now, I've got my number one priority.
You can fix a bottom bracket in two ways: you can overhaul it and put in new bearings manually or you can put a sealed bottom bracket in it. Sealed bottom brackets cost a little more, but they last a lot longer because it's harder for junk to get inside and start to wear them down. At Bike Kitchen, they've got a whole bin of sealed ones so I decided to put one of them in.
To get the old one out, you have to use the aptly named crank-puller which basically pushed the cranks out from the bottom bracket.
afterwards you can see just the end caps and the spindle of the bottom bracket are left.
After removing the end caps, a fairly destroyed set of bearing came tumbling out afterwards. And inside you can see that the interior looks pretty roughed up.
After I cleaned up the inside, the sealed bottom bracket definitely looked a lot healthier sliding in there.
Now the wobble and the friction are both gone! On to the next fix.
