Fitting rear wheel
 

Hi,

I have just replaced the rubber spacers in the rear hub of my 4PT with new ones and found that I now can´t get the wheel to slide into the rear sub frame as the hub´s too wide. Any suggestions? I am doing this in a garage and can´t see how I´d ever do it in the desert.

Thanks, Finian

The same way you **** a donkey : just force it in! The rubbers will soon take normal proportions so next time it will be easier.
Why would you want to take the rear wheel out in the desert? Make sure you have Michelin Desert tyres, so you won't have to. I just did a few thousand kms of desert [see ]www.aiofrance.com] and was not sparing the tyres at all, without problems or even a puncture.

OK, thanks, just thought in case of puncture.

"**** a donkey"
"rubbers"
"normal proportions"

Have I landed on the right site????????????

Cush Drive, boys........

Probably worth knowing how to fix,
the only puncture I had so far in 10 000km through Africa was in Sudan in thick sand!

Somewhere along the way, I picked up a nail, which worked it's way through my Pirelli MT21's and through my doubled up extra heavy duty tubes!

great fun fixing it in a sandstorm!

I had my Cush Drive apart when I first got my bike and giving it a general clean. There was no sense of tightness then, but this would have been after much use.

Are new Cush Drive Rubbers so very tight from new? With so much apparent compression, are there Polyurethane alternatives that would retain good shape for much longer?

Finian, I wonder if it is worth checking you have the correct part? If I understand the dynamics correctly, then the compression after use could make them spread and difficult to fit the wheel. Yours are new and are starting 'thin', mine where used and did not appear to have grown in width to make the wheel difficult to fit. Hence it might be worth checking the part (and fitting - are the joiners stopping the veins seating properly?). Just a thought.

Ciao, Geoff

And make sure that the little 'bridges' between the small and large rubbers are on top of the things in the hub and not the other way around.

Well, in the end the only way I could get it in was to cut off the little bridges. There was just no other way that I could see and I didn´t have the patience. Maybe if you were to take it to a mechanic they could do it. Anyway, I don´t think its important, and made it go straight in. As for the theory that they get bigger over time, I don´t buy it. I think they just wear out. Certainly its a much tighter fit than it was with my old ones and which were visibly worn, hence the replacement.

whether fitting a tyre or shagging muffin the mule, lots of lubrication and it should go
