Back to the known...

 I  know computers about as well as Russian Braille. Bike issues on the other left hand...

  When cartridge bearings get nice and gritty (as they all do with use in the dirt). Just like ball and cup style, you can prolong their life with a bit of cleaning and fresh grease.
I don't carry a bottom bracket tool and after searching a few shops with no luck... I went rogue. Street side. You can leave the cups in the frame and tap out the cartridge carefully from the inside.

Pick the seals off both sides and behold the nasty traffic yer bearings have been commuting in.

Scrub 'em out with gasoline in an old ford hub cap with yer favorite toothbrush

Mash in some fresh grease and replace the driving blinders

The important part- yes, as always, it involves a hammer. I found this ancient crown race that is the exact outer diameter of the cartridge. Its best to reseat the press-fit pushing on the outer race of the bearing. Tap that whirly duder back in...

and go have a coffee!


  1. For a smooth ride it is mandatory that greasing and servicing of the bike is performed at a regular basis.

  2. Wish I had your confidence in technical matters. I have endless trouble with my BBs - and I just don't have the wherewithal to resolve it so neatly, roadside.

  3. Well If I happen to bump into you down the road. I will gladly help you with some tips and lessons.

  4. Bruce, Thanx for the reminder. Its pretty easy to let things go and before long they are destroyed. Fairly regular matinance can really get alot more life out of things.
