Hi All,

I bought a set of Tuff II's a few months ago and upon building my Supergoose, I stumbled upon a problem...

In a previous life it appears that the Rear Wheel has had the spindle overtightened causing the metal hubs to pull in toward each other. This has then caused the Freewheel to move inwards, thus causing the Chain to not flow straight.

Has anybody overcome this problem before?

I think I need a Rear Wheel Rebuild kit, but don't know where to find one?

Any/All help would be much appreciated.

Many thanks,

Steveis28

If the wheel still spins freely and the freewheel isn't rubbing on something you could just adjust the alignment of your bottom bracket.

If you have a 3 piece crank that utilizes a "floating axel" this is very easily accomplished by using aluminum spacers to adjust the tracking.

This is assuming that the freewheel CAN be aligned with the bottom bracket to begin with (meaning there is enough clearance).

If that's not possible - yes, I rebuild kit is most likely the answer - however it would need to be a rear rebuild kit.

Steve:

85 Master Mike D has is right as far as I can tell. If you can get the front sprocket to move inboard by adjusting the bottom bracket that is great.

Hopefully the chain will not contact the chain-stay after the adjustment. If it does, try using chain tensioners to maintain the tension at the highest possible level without binding the chain.

I hope I am understanding your question and giving a clear answer. There are many here much more knowledgeable than me on these boards.

One other possibility is that you only need new bearing cups. Uneven wear on bearing cups can also cause the freewheel mechanism to move inboard in relation to the frame.

Sometimes disassembling the axle mechanism can reveal a whole new issue with cone nuts, bearing and the rest of the components.

I think this is what 85 Master Mike D meant about binding in the hub. Even without binding, you might have seroius alighnment problems in the bearing cups, ball bearings, and cone nuts. Take it apart, take pictures, and we will get a verdict.

Or you could just take it to your local bike shop, Emphasize that this is a treasured wheel, and tell them to call me at Skyway for parts.

Do you have any pictures?

Any other ideas from all the real experts here? Honestly, I just make Tuffwheels, I have no idea about repairs.

Good luck! We await more details! DETAILS!

i'm assuming you mean that the hub flanges are crushed/squeezed inward(?). if so, that was pretty common. not sure how much overtightening things play into it, but kick-out/rockwalk/sideloading type tricks will cause that.

anyway, besides everything else mentioned above check to make sure that the freewheel side (especially) is bent "straight"...meaning that when you spin the wheel that freewheel spins straigh - not wobbly. if the flange is bent more in one spot than others the F/W will not track straight. if the flanges are still parallel the wheel may still be rideable.

did any of that make sense?

Dude Mr. CoasterBrake:

I bow to your knowledge mifriend. Thank you!

Hi Chevron Envy, BartWatchitDude and mr coasterbrake,

Thanks for your input.

The crank I have is the original 1-piece mongoose crank, and as for the Frewheel, it does wobble and so what I think I will have to do is see if I can make some sort of tool which will help to straigten the flange out and then refit the freewheel and see how I get on - and yes mr coasterbrake, it all made sense cheers...

As for the axle and bearings, I replaced these at the weekend and although it did help (as the wheel had been left in a poorly aligned state) the freewheel just seemed too close to the flange and seemed to float/wobble.

As for the parts BartWatchitDude, are the flanges still available as a kit?

I'll give it a go with the tool which I will make and see how I get on. I'll keep you updated...!

Thanks again, your words have helped a great deal.

Cheers,

Sorry, not from me. If you find one, good luck installing it!
