help finding a multiple freewheel sprocket lockring tool
 

Anyone know where I can locate a sprocket lockring tool for the Shimano MF HG22 and similar freewheels?

I know a hammer and puch is a viable option but am looking to see if there is a more specific tool available.

Also, just to point out I do mean freewheel and not freehub. Also I do not intend to dissassemble the freebody, just remove the HG sprockets so I don't need a reminder on how difficult it is to rebuild a freebody.

Thanks in advance:)

Cog spares for freewheels went out in the 90's. what do you hope to accomplish?

There is a factory tool for production, those engage all the notches,
and I expect is part of an Automated manufacturing tool ... which is why
a part shipped around the world is still selling for less than $20..

Older Freewheels thread the cogs on. Chain Whips grab and unscrew them.
Regina , and Sun Tour and Malliard are all gone, as companies.

Good thought. That led me to this http://bikeforums.net/attachment.php...hmentid=273718

Has anyone been able to remove sprocket lockrings with these pliers?

Good source of hyperglide sprockets that with some modification can be used for building up on better quality freebodies such as the MF 7400. Or so I have read.

The ultimate goal is to achieve modern smooth downshifting on an freebody that will lasts 1000s rather than 100s of miles.

I have been finding some more good information.

Here is a really great thread from a different forum discussing disassembling these MF HG22 freewheels and converting them to a single speed. Nice way to reuse the freebody and also use the sprockets for other conversions.

Found a member here, borland, who has done this.

He also references a write up about the conversion with modified 17 tooth sprocket here http://bellsouthpwp.net/k/a/kaeru41/freewheels.htm

Finally, here is write up from bikepro.com about the conversion with the addition of making it into an 8 speed freewheel.http://www.bikepro.com/products/freewheels/tnt.shtml

Here is borlands picture.

I realize at this point I am basically writing to myself on this thread but after spending a lot time searching all this stuff out there might be some values to others someday to have it referenced all in one place. At least I'll use it.

I found another option.
