CVT NuVinci freewheel removal, How ????

[POPS]

Hi guys

Just like the title says.

Does anyone know how to remove the single
freewheel on the hub?
I have seen on some sights that you have
to have a special tool to take them off, but
I don't understand why because in the install
instructions it says to lightly grease the threads
and screw on finger tight. Can I not take a punch
and lightly tap on the teeth of the freewheel to
remove it ? I bought it used and it was already
assembled and it has a lot of side to side play.

Thanks in advance for the replys...POPS

cut it off

Hey Pops, I had to cut one off. There is no tool. Be very careful & use a disk on a grinder. One slice is all it takes. Once you get close then you can finish it off with a heavy duty flat screwdriver. As tweety bird once said "Be Vewy - VEWY CAWReFUL!! You can do it - I did.

Thanks Zomby

Can I not take off the snap ring and remove the

freewheel adapter and freewheel as an assembly

buy pulling it off...(NuVinci site) ???

Then getter in a vice and tap the bearing off ???. Thanks..POPS

Remember, the pull of the chain tightens the freewheel...

Thanks for the reply but there is as much as a 1/4 in. play

in the freewheel/FW adapter and I think that is too much???

Is the play side to side or front to back like the pawls are working but just old.

I saw where you bought it used just now.


They do get extremely tight . I have never been able to remove one by hand. I always had to cut the old one off .
And then laugh at the ease of reassembly.
This is for the freewheel only not any bearing in the cvt right.

thanks for the reply

I have a new hub and the used one. They look different when you look close up. The new one has a snap ring which is there to take off the freewheel and adaptor at the same time so I've read, and the old one does not have one. I read somewhere that there is a special tool to take it off.

If you are faceing the freewheel and grab on to it, it has at least a 1/4+ play side to side and up and down. The thing that really worries me is half the play is in the freewheel and the other half is in the freewheel adaptor which is somehow mounted to the center of the hub. Thats the part that scares me. It moves all over the place and I do not know how it is mounted on the hub.???

Any help you can give me would be great...Thanks...POPS

You would probably be better served by contacting him if you suspect the nuvinci hub is damaged.

On a free wheel i would replace one with that much play.
It may be just be a loose setscrew ?
Post pictures if possible .
I know that sounds like a lot of fuss as I do not have access to working camera. myself.

I don't know how to post pic's and my putter is getting ready to crash I think. Seems to be haveing problems with Kodak?

I do not know where the set screw is. Can not find one any where.

The freewheel wobbles a bit on the inner part and outter part of itself but what really concerns me is that the inner part of the freewheel screws onto the freewheel adaptor and it is the freewheel adaptor that wobbles a lot on the shaft???...POPS

There is no adapter on that hub. There is a spacer on the inside that may look like one, but it is just a washer. It is a one piece - thread on freewheel. China 22 tooth. I know because I put it on. CUT that off if it is wobbleing.... I had to do it on my other NuVinci, replaced it with another freewheel just like it. No snap ring there either. Lots of torque on that hub. Never get it off without cutting...............Be cawefull!
