Chain tension bolt - siezed & sheered - Help

[Milky]

Probably gonna get completely slated for this..

The photos explain it all...



Completely siezed..good old Kawasaki and they're resistance to corrosion. The head's sheered off trying to get the thing out! Wheel ain't moving/goin outta line i've been riding like it for a couple months.. luckily it's not on the chain side. Ive got stainless steel replacements to go in. Chainside tensioner is fine but this one's well and truly f*cked..

I know the only way to do this is to either heat the swing arm up and use an extractor tool or drill it out and thread a new hole etc.. But I don't have any of the tools to do it. £50 to anyone that can get it out leaving the thread intact and paint on the swingarm!!

That sounds like a challenge! When you free for me to attack it?


Oh, and....

Soak it well with WD40 or plus gas or such, does the sliding bit come out to give you better access? then take a hammer and punch and give it a few sharp taps then try to turn it with mole grips slowly does it though. if you get it to move a little one way do not force it too far and shear it off again, just wind it back again then forward again , keep adding lubricant and working it back and forth moving it further and further in little stages eventually hopefully it will come out

As Merv said, but once you've soaked it for several hours in WD40 or duck oil then heat the crap out of it with a blow torch till its red hot then try turning it with mole grips. Otherwise if you have access to a welder weld a bolt to the remaining stud and try turning it that way. Took three goes and several soakings with wd beforeI got a stud out of of my old Bandit barrels.

Slow and steady is the answer.....




Oh and like Varcon said......

you might get lucky and get it out, but I will be very surprised

as already mentioned, I would give it liberal soakings in a penetrating oil, leaving it for as long as possible.

heat applied to the bolt will help but its the alloy you want to get warmed up, as it expands faster than the steel

dont go heating the bolt until its cherry red etc, then you are screwed LOL, probably a hardened steel bolt originally, heating it to cherry red then letting it cool, will soften it.

good vice grip or mole grips will be a help, not cheap shitty poundland ones

not a lot of room for movement in there, but good luck with it

if you do get any movement, then as already mentioned, dont be in a hurry to rush it out, work it back and forth, like your tapping a hole, let it work its way out.

Were it mine I would use a Dremel to cut a slot in top of the bolt, then do 2 nuts up against each other ontop of the slot, then stick the biggest flathead screwdriver i could in there(on second thought would probably use a flathead hex bit on a ratchet with an extension) and undo it slowly. all this while soaking it with wd40 etc.
