Hi,

On the SB6 there are 8 x hex screws that fix the rear bodywork to the frame (4 each side) and mine are all stuck solid! I’ve rounded the hex off on most trying to remove them. Does anyone know of any tricks to get them out, or am I going to have to resort to drilling them out?

Thanks.

Hello,
What I would normally do is as follows:
a) get a dremmel
b) fit one of the little cutting disks thingies on
c) use the disk to cut a flat deepish cut into the head of the hex screw
d) You've just made a flathead screw.
e) Spray some easing fluid all over the screw esp the back if you can get at it.
f) Get an impact driver with the right bit on the end of it.
g) Gently whack it until the screw comes out

Might be hard to find a replacement for the screws, but maybe can cover them up by smearing black silicon seal over them once you're done
Hope this helps!!
Louis

Thanks for your reply. I've used the "Dremmel method" before, but these screws are v. small and flush with the bodywork, so I'm worried about damaging it. May have to risk it if all else fails, though.
Thanks again.

Have now managed 1 of the 8!! The lowest screw on each side protrudes through the frame, so I thought I'd get the hugger off and try mole grips on the thread end of the screw. Guess what, the hugger hex screws were impossible to remove and 1 of the 2 cross heads too. What is it with these fasteners?

Finally dremmelled the hugger screws off and the mole grips worked on the left hand lowest bodywork screw. Won't be able to use them for the rest of the b*******, though Sad

Two days work and one screw removed!

For anyone else who has the same problem, try this:

Get a Trend Pro Grabit Screw and Bolt Remover, available here: http://www.screwfix.com/prods/21391/Drill-Bits/Specialist-Drill-Bits/Trend-Pro-Grabit-Screw-and-Bolt-Remover-2-Pieces?cm_mmc=GoogleBase-_-Datafeed-_-Drill%20Bits-_-Trend%20Pro%20Grabit%20Screw%20and%20Bolt%20Remover%202%20Pieces#

Drill a 3mm hole in to the end of the fastener. Use the smaller extractor from the remover kit in a low speed drill (cordless is good) and wind in the remover until it bites. Remove the drill leaving the remover in the fastener. Wind the remover in using a socket set or similar (drills spin too fast and you lose the bite). It's vital to keep pressure on the remover and wind it slowly.

Managed to remove all the screws using this method Smile

Also Screwfix had identical replacement stainless countersunk screws (M6x1.0x20) to use to put the bodywork back on again. Result.

Use copper grease on the threads. Stainless and ally aint a good mix especially if it gets wet Wink

You could also try gently hammering in a hex key of the approx size, the extra edges will hopefully bite into the screw and enable you to unscrew them, I did this with a seized fastener on my Bim.

I just did a track day on my SB6, when i came back to the pits after the first session, i did a quick walk around the bike, to my horror i discovered that all 4 screws on the right hand side had fallen out Shocked

I had previously replaced the originals with stainless fittings and used loctite to keep them there. Using grease would only make matters worse, wouldn't it? I assume the loctite would form a barrier to stop corrosion?

Cheers

Yep, your right, I'm wrong Laughing
But... it's worked for me on two SB6's and a SB6r. When I loose my first bolt, I'm gonna use your method Wink
