    How To Regrease Sealed Bottom Bracket?

    I'm getting ready to sell my Windsor Cliff 4500, but before I do that I want to fix several things, one of which is a "tick" that appears to be coming from the bottom bracket. I've got the bottom bracket off, but how do you regrease the bearings in a sealed cartrige?

    Also, any tips on how to clean up the bike in general would be appreciated (e.g. getting grime off the chain, etc).

    I'm a newbie too, and I found this guide really useful.

    I don't think sealed BBs can be re-greased. You probably have to buy a new one.
    New rider, MTBing is fun!

    Thanks for your response. On that note, I do have a new one that got sent to me to replace the bottom bracket of a different mail order bike I had, but it was too short. The spindle appears to be the same type, but the one that came off the Windsor is a 113, and the replacement I have is a 108. Does anyone know if these would be compatable? I was able to partially install it to test the fit, but I haven't tried to tighten up anything - below is a photo of the potential replacement bottom bracket partially installed on the Windsor (and yes, I know, the bike needs to be cleaned up a bit!):

    Here are the links to the one that came off my bike and the new one - sorry if the answer is obvious - I'm still learning about all the technicalities:

    The one that came stock on the bike (photo shows 118, but I have the 113):
