    3000K maintinance question

    I'm going to replace the chain as it has worn 1/16 of an inch over 10 links. I want to clean and relube the bottom bracket. I've done this before with richy and shimano but this one is Campy. Anyone know what size the allen key is to remove the crank? 6 is to small and 8 is to big and who sells a 7mm? The little disk with the 2 holes-does that come of before or after lossening the allen bolt. Do I need a new puller or will the park tool that works on ritchy work? This I can figure out once I have the allen bolt off. The rest is easy to me. Should I just take it to a shop and let them do it?

    They are usually 8mm and sometimes 10mm. a
    The "little disc" is a crank extractor (I am a Shimano guy, so Campy people please correct me if it is different). Leave it in and back the allen bolt out. The allen bolt will push on the cap and push the crank off.

    The real deal though is that nowdays bottom brackets are sealed units. There won't be anything to lube if it is a modern bike.

    The Park tool website is a very good guide to maintenance and tools.

    You must have meant 3K or 3000, 3000K is 3,000,000. Anyhow, I have over 8,000 miles on my drivetrain. No plans of replacing it. Just a good cleaning and lube every weekend.

    No I ment 3000K. K for Kilometers. Just talked to a LBS they say all campy is 8mm or 6 mm and I must be using the wrong allen key. I could have been wrong so I checked again. Definately a 7.mm. Funny no bike store around here has one. Home depot here I come. The sealed unit is probably what I have being a 1996.

    the short is km for kilometers. 3000k means 3,000,000.
