|My no nonsense, quiet, and easy to remove bottom bracket install. Why? With all the complaints of loose bottom brackets, damaged threads and squeeks I hear about, this is my answer. And even after a couple of years in place, removal remains as smooth as butter. It's not a lot of extra hassle.|
First things first: Drill a drain hole in that bottom bracket shell. I know this is often debated, but even living in mostly dry northern California I'm constantly amazed how much sludge spills out of my undrilled shells.
Use a center punch to mark the drain point and to prevent the drill bit from walking all over the nice paint.
|With a 1/8" drill bit, do the deed.|
|Check for a lip inside. If it's there, take it down. I use a Dremel 9903 carbide-tipped bit, the same one I use for drilling out cable stops.|
|Use a hooked tool, scribe or razor blade to clean any gunk out of the shell's threads left behind from a previous installation.|
|I always like to do a test fit, to ensure the threads are in good shape. Just a couple drops of oil on the cartridge...|
|...and install both sides hand tight to verify there is no cross-threading. If the threads are buggered and this step meets excessive resistance, have a shop chase them.|
|Wipe the threads down and apply a finger full of Permatex Anti-Sieze lubricant. You'll be able to find this, or something similar, at most hardware and automotive stores.|
|Wrap two turns of teflon pipe thread tape to each cartridge adapter or cup. Pay attention to the direction so that the "tail" of the tape is facing away from the direction of rotation.|
|It's going to turn in with more resistance than during the test fit, so take your time, make sure it's straight, and start it by hand until you're positive you haven't cross-threaded anything.|
|Here's a handy trick: If you have a hollow spindle, you can use a rear wheel QR skewer to hold the adapter in place for final tightening (this work even better for sticky removals). You'll need an appropriately sized socket to drive the adapter because the square hole your ratchet normally engages is taken up by the skewer.|
|Torque appropriately (50 foot-pounds for Shimano cartridges, check your installation sheet for others).|
