Smaller shimano cassette tool

[one-eyed_jim]

There's a small difference between the spline pattern used on a Shimano freewheel and the standard Shimano cassette lockring. They're very similar, but not quite compatible.

You need a Park FR-1.3 tool, or similar. See the pictures here:

It seems there's also a bit of confusion about terminology. "Uniglide" refers to the tooth profile of the sprockets, so there were threaded Unglide freewheels as well as splined Uniglide cassettes. We're obviously dealing with a freewheel body here.

I'm not worried about the ratchet I just want to get the wheel. I have the correct tool and have put massive weight on it. Not yet a vice. Just wanted to.make sure there is nothing I missed. The only things left seem to be the axle nuts!

The only reliable way to shift a well-used freewheel is to sit the removal tool in a vice and turn the wheel.

If you haven't got a good bench vice, it's the kind of thing a decent bike shop can do in thirty seconds.

Correct. And this tool also fits some of the maillard/sachs splined freewhells too. However, there is an even older shimano freewheel, which is what I referred to, on which the "hole" is much smaller - you have to remove the locknuts to even get the remover in.

It's off!!
Stuck it in a vice and 2 of us turned the wheel!

good. Let the build commence

well done on getting it off! I always thought Uniglide was the cassette type arrangement, not the twisted tooth design of the actual sprocket? Freewheels are a little bit before my time though.

If you go back to the contemporary Shimano catalogues, they use "Uniglide" to refer to the tooth profile of both cassettes and freewheels. Here's a cassette system with "Uniglide Teeth" from 1982:

a cassette system with "New Uniglide Teeth" from 1985:

and a freewheel with "New Uniglide Teeth" from 1986:

Likewise, "Hyperglide" refers to the tooth profiles of later cassettes and freewheels.

It's complicated by the fact that Uniglide and Hyperglide cassettes use different attachment systems, and most of the traffic on this site is probably more interested in the cassette hub era. Strictly speaking though, "Uniglide" refers to the tooth profile, not the cassette system.
