Title: Seized chain guard bolt
Post by: Kentish on 02 March 2014, 08:01:17 pm
I've been doing a fazer up that I purchased. I have come to remove the tax disc holder someone has put on using the rear chain guard mounting bracket. The bolt is seized it's an Allen head and it's been rounded off,heated it,used a snap on bit in it no good,mole grips,even welded a nut on it and when I turn it the bolt just bends it's ready to snap.

I was just going to let it snap then drill it out and use a nut with a bolt behind. Anyone else done this? Don't want to give it anymore stick and end up snapping the bracket off the swing arm

What are those things you can tap on the hole with a thread on?

I think you might be referring to a helicoil or a 'tap and dye' set.

Sounds like a tap and die set to me as well

Think I will just drill it out and use a nut behind it. Seems the easiest way

Tap and die sets are brilliant everyone should have one for cleaning crusty nuts and bolts or cutting new threads. Best fifty quid I've spent!

Try a  screw extractor set.


Drill a hole down the centre of the bolt (smaller than the thread), then insert the screw extractor. It's reverse threaded so as you turn it to undo the bolt, the extractor tightens it's grip on the bolt.


I find the hardest part is getting the extractor to grip the bolt at the start (that's possibly due to a cheap tool), but once it's gripped it works really well.

I use valve grinding paste to clean threads
