Can someone give me any insight on how to remove the freewheel cassette on an old Shimano 600? I already have a Park FR-2 which is slightly too large to fit the notches in the freewheel. I can grind the teeth down to fit it but I want to know if there is a proper way to remove the freewheel.

There are also two small holes and the word "unscrew" on there. I assume removing this will provide access to the ball bearings.

This is inscribed on the freewheel body:
Shimano 600 Japan VIA MF-6207

Same tool but the legitimate one has notches to fit the freewheel. If you want it you will probably need to special order. If your tool is an extra just grind to match. Small holes are to gain access to the freewheel mechanism. Never had need to open one up. Maybe someone else knows if it is serviceable.

You could remove the freewheel buy destroying it,if you have another one.You must realize that with a short axle it will be hard to remove and strip the freewheel notches.

Removal by Destruction


That hole in the freewheel tool is for the axle to go through and also anchor the tool in the notches of the freewheel with a bolt.Prevents the tool from slipping and damaging the notches.If those notches get damaged you will have to destroy it.

If its worth it take to bike shop.

I had one of those BR tools. It is made with very soft metal and I sheared the notches off on a stubborn freewheel.

Like Adohrn says, modify a two-prong Suntour removal tool and it will work like a champ. I have one that I modified in my toolbox.

thanks will modify. sure beats spending $20 on a one-time use tool.
