I like the Park Tool site too. If you have Shimano components, they have all their factory service documents on their website - don't know if the other component manufacturers do the same thing.

For an older manual ... my first ten-speed I took apart and reassembled nearly everything on it - including the freewheel, after I found the pawls and springs when they went everywhere - with the Clear Creek Bike Book. Who else remembers that?!


But, I don't do seals. I let the LBS take care of sealed bearings.
