I'm having real trouble opening the bottom screw (8mm allen head) in the K1100rs fork to dismantle it for new seals.

I'm guessing it's oxidized aluminium holding it in and so far I've tried heating the slider around the bolt gentle and sticking a welding rod to the bolt to heat it, In the hope of a bit of thermal shock breaking the grip...nothing. I've just wrung off an extension bar on the hex socket trying to open it and still no budge. Penetrating oil can't get past the O ring I guess so I'm deviod of ideas....any suggestions please forum Gurus?

Some physical shock, use a good size punch and a solid hit with a BFH then use an impact gun and if that doesn't do the trick drill the head off it.

I wonder if some knucklehead used red loctite on it.  That would call for a good heating and a new o ring.

Will, I never approach a set of forks without an impact driver and a BFH in hand. You've got one, seems like you need to buy the other?

Went to the Auto shop yesterday afternoon and splashed some cash for an impact driver and a long enough set of Hex keys. It' still took a breaker bar after hitting it a couple of good cracks of the "Gentle Persuader". It's probably because I'm an amateur that I get so nervous of these techniques, especially when working on Aluminium!

Thanks Guys. The new seal is already in!
