Please forgive my newbiness.
The freewheel on my ooooold trek 1000 sounds horrible. I'd like to take it apart, lube it, see how it works, overhaul it, and put it back together. How do I get into the actual freewheel? Baring that, how do I lubricate it?
The freewheel is a Shimano MF-Z012, circa 1988
Thanks for your help.
