[Dave G]

While attempting to change my front sprocket I managed to strip the hex end of one of the allen bolts holding the clutch slave on,not the thread which is intact and as tight as ever.
Any ideas on what to do next?
Its the most innacessable one too!
The allen key just spins now,dont know why it happened as I've never done it before
Anyone else done it?

Had a few Dave. First attempt is with a torx bit. You'll have to play around with a couple of sizes to get on that's snug, and then tap it in place. Then use an impact driver to try and shock it. Don't just try and turn it. It'll strip out again.
If that fails, drill it. Use a 6mm bit. Just go far enough for the head to come off. Once the head is gone, remove the cylinder and then you'll have some of the bolt to get a hold of. It'll probably come out by hand, but if not get some mole grips on it.

Once off if it wont shift with grips, weld a nut onto it. This not only gives you somthing to put a spanner on but nicely heats everything up and gets it moving.
