Hi,

What seems to be a simple task turns out to be quite a job.

I’m trying to unmount the rear shock on my BMW R100GS. The upper and lower bolts are removed along with the rear frame. I ‘ve pulled it about 4mm our from it’s “mounted position” - but here it seems to be stuck. I ‘ve also removed a rubber o-ring from the front and pulled one out of the lower shock mount towards the wheel. It currently have a lot of wiggle room when I rotate the shock.

Any ideas of how I can get it off?

The shock it a TechnoFlex 640.008.001 from 2000.

Thanks,
Casper

Impossible to answer without knowing what bike you are talking about?

I tried searching for that shock to see if I could match the model number to something but no luck, so yes, we need to know what bike

Oh yeah- sorry about that.

It's a R100GS 1994.

I have had fun trying to remove the rear shock from my GS in the past and have found the only way is to use a piece of wood as a drift coming at it through the spokes and hitting the wood with a hammer, it helps if you have someone else support the shock as you do it. Plenty of copper based grease on reassembly should help prevent it happening again.

Wondering if I should remove the bolt which the shock mounts on – number 25 in the attached diagram. I can't really tell how big an operation that is.

Yeah I've actaully tried that before I unmounted the rear frame. At that point the real wheel was also removed, so I had nice access with a large rubber hammer to beat it.

I later unmounted the rear frame to be able to rotate the shock out of it's upper bracket – to give it more wiggle room.
