The cranks... they go round and round
In other news, when I put my Sunny Day bike together, I was in a bit of a rush. So I didn't overhaul the bottom bracket or headset. Well, yesterday I noticed my cranks were really wobbling and desperately needed adjustment.
So this morning I decided to overhaul it.
The right crank, still bearing the dustcap over the axle nut:
With dustcap removed, you can see the axle nut now:
After removing the nut, the crank removal tool threads into the crank itself. The tool then pushes on the end of the axle to separate the two:
Removing the fix cup, note that it has reversed threading on this side (righty loosy, left tighty), except for old fucking French BBs:
Cup, bearings (in a retainer), cone, axle. Noticed the thin coating of grease (probably white lithium), it's a little brown and crusty, but I've seen far far worse:
The inside of the BB after I've removed everything. I'll grease up all the threads and pop everything back in in the same order.
The whole assembly including the adjustable cup and BB lock ring (after cleaning, before greasing):
I'm not going to go into the full spiel about BB adjustment, other people do it better. Plus any newer bike is going to use a sealed cartridge bearing BB which means you don't have to do any of that stuff. Suffice it to say my BB is running smoothly now without wobbles and was very nice to ride into work.
In other news the bike shop finally heard back from Surly. They want to look at frame, so it's being shipped today or tomorrow out them and then I should get new frame in a week or two (assuming nothing goes wrong).
