Removing freewheel MF-Z012 without tools I'm trying to just add some grease to an old MF-Z012.

some pages online says i can remove it just by spining the first gear agains the last one.(e.g. http://www.cyclebanter.com/showthread.php?s=e4a1c90962d5cdf765e2fd15d37c96cd&amp;t=75231 )

i can easily fabricate some chain whips with an old chain and vise-grip and try it... but the question is: is this true? or will i just waste time?

the freewheel does have a connector for a TL-FW30... but I do not have said tool and am more concerned about time to get one than price.

So, did anyone ever removed/installed a MF-Z012 by just spinning the smallest sprocket?
The answer is in the question - freewheel, not freehub or cassette. You will be needing the tool and a vice (or huge adjustable spanner).

Remember to put the skewer or wheel nuts loosely on to hold the removal tool in place whilst you give it the initial heave-ho. Thereafter take the skewer/nut off.

If you don't want to do it/fork out for the tool then ask your friendly local bike shop - it is a given that they will have the tool. Go with your big adjustable spanner and borrow the tool for five minutes (remembering to buy something) if they insist on charging you £10 for the job.
