Brompton rear suspension bush

[Ugly]

My brompton needs the rear suspension pivot replacing. Is a replacement kit available? How do I go about the job?

The rear suspension pivot can be obtained; the screws on the existing one must be drilled out. Fitting the new one is no problem and its screws must be Loctited in. Usually the bushes are OK but these must be replaced by the factory. You may have to order the spare pivot through a dealer, or else try http://www.sjscycles.co.uk/product-Brom ...

You should be able to shift the screws with a well-fitting allen key. They sometimes unscrew themselves - the recommended torque isn't that high.

You don't say why you need to replace it. I've had to replace the bushes twice. The Brompton kit for that job comprises the bushes, the shaft, the screws, an allen key and a drill Both times I had no joy with the allen key and had to use the drill!

If the bushes are worn now might be a good time to replace them. Once the bushes are inserted you need to ream them to give a precise fit for the shaft (B recommend that you use a very expensive tool to do this but I just used a standard reamer - perhaps this is why I had to do it twice!). You are supposed to use the high strength Locktite to retain the screws (this stops them unscrewing but means that you'll have to drill them out again next time....).

Just to make everything just that bit more confusing all the components are imperial not metric.

The last time I did it was a few years back but I doubt if anything's changed.
