need weird tool to remove cassette body... HELP !!!!!!!kenny
Dec 26, 2001 4:24 AM
I have a Rigida wheelset and I need to replace the cassette body(it is starting to miss and skip,so before I go over the bars I need to replace it!) The body is connected to the hub not by a large allen key bolt (like normal) but by a large special bolt/nut,that you need a "lockring type tool" to remove it.There are 12 points of contact and they are pointed,not square.The hub itself has a threaded protrusion that the cassette body threads onto ???!!! The hub has no markings or numbers on it,it has an 8 speed shimano cassette on it,it is slotted for the bladed spokes,nice polished hub too! Nobody here in West Palm has a tool,or a clue on what it is or how to get it off,or to find a replacement.Please HELP!!!!!!!!!

It sounds as though you have an 8 speed freewheel, and to remove the freewheel, you'll need Park tool FR4:

But you say that you have a Shimano cassette, in which case, it could not be a freewheel.

My recommendation is to take it to the oldest mechanic you know of, as freewheels went out of style a few years ago (but not so many that most bike shops would have forgotten about them!).

Is the description of the big "allen" key deal. It could be that he's simply describing the axle.

Either way, you either just don't know what you've got or have never seen a cassette removed. I agree, take it to a bike shop.

If it's not a freewheel you need the similar tool to the freewheel tool except it's for the cassette lockring. They look a lot alike. A chainwhip would be helpful removing the lockring or freewheel either way. You can muscle it with a rag over the cassette, but a chainwhip makes it easier.
Thanks for the replies but.....kennyclean

It is a "cassette". I have already taken off the "cogs" now I need to take off the cassette "body" from the hub,it is usually connected to the hub by a #10 allen bolt,the way "this" body connects is you have to use a special tool that "looks" like the cassette lockring tool. Only its a little smaller and the edges are pointed, not squared off.The wheels are less than 6 years old and they are great but the pawls inside the body are goin' south! Thanks again for your time! First time on this site, pretty cool!!!!!

Or I try to read too fast. I completely missed the "body" after "cassette" the first time around...

Have you tried putting an allen wrench down there? Oftentimes, there is a star-shaped nut in there that is designed to let you put in a wrench from a variety of angles. It doesn't look like a wrench will go in there, but they will. Try throwing a few wrenches in there, and see if you can't get one to stick. I'm inclined to believe that this is the solution, as you mentioned 12 points, where a 'normal' nut would have 6- so it's just designed to hold your wrench in 2X as many places...

I will try that...thanks, and if it works, do you know where to find another "body" that connects like that,like I mentioned before, the hub itself has the threading and that cassette bolt/nut threads "onto" it. WEIRD ,I know, but thanks for you time!!! One shop thought dura ace a few years ago had this weird set up. What do ya think?!

I suspect that there is a bolt going through the hub that screws into the freehub body, but let's hope it becomes self-explanatory once you get it apart.

are you SURE it's the freehub body??DAC

You mention that it is starting to "miss and skip", which sounds to me like a WORN CASSETTE. I'll bet that you have just replaced the chain, and this started to happen?
If it were gunked-up and sticking, yeah, you should take it apart for cleaning. If it were jammed, then it would need to be opened up. I'm betting that once you pull the thing apart, you will find nothing wrong with it. you will clean it, reassemble it, ant the chain will still skip. Replace the cassette, and it will work.
