as some of you may know, I recently got a rather good bargain in a new rear caliper and torsion bar. Having now fettled the rear caliper I decided to fit it, undid caliper from torsion bar, swopped calipers so far so good. Now about to change torsion bar cause the fitted one is very rusty and new one is well newish. (getting old one powder coated red). The trouble is, the torsion bar bolt securing it to the swinging arm is securly welded into place with rust and corrosion. Now I have tried everthing from gentle heat, cold spray to lump hammer and it aint moved a iota. I have even attached impact wrench to try and vibrate it loose but no joy. Any suggestions would be welcome.

Hi Is yours an 11 or 12 either way if I was i was in the same situ I would try one of to things grind/saw head of bolt off and nut if still attatched ( as on a 12) drill through and use an easy out .
If this is an 11 and uses a threaded lug on the swinger and easy out is no good I would drill through and nut and bolt it instead.
Once had a torsion bar snap on me in Blackpool had to ride home pissin it down after having removed the brake pedal . entertaining to say the least.

its a 12, so has a square head on the bolt, which is located by lug so that it dont move when undoing nut, the nut comes off sweet, but the bolt has corroded itself into the hole.

Their is no thread in said hole to ruin in the lugg . As its an ally lug and steel bolt they have ionised together . If the wheel is out you could if not already welly the bolt from the inside. Not to heavy handed as its an ally lug . If your worried about scratching the wafer thin avodizing on the swinger drill it out from the inside.
When you have suceeded COPPER SLIP the new fastener.

Good advice from Kes. If you hadn't already realised, you'll need the wheel out anyway. With the wheel in place you can't get the bolt out enable removal of the torque arm to begin with. Working from the inside you just might be able to get a grip on the square end with a spanner or something and free it that way. Failing that, lesson one from The Gremlin School of Mechanics says someting about , if at first you don't succeed, use a bigger hammer.

I have just had the same bolt shear, bodged another bolt to fit. Sorry to pop into your post trucker but Im cheeky. Anyone got the bolt measurements or could be arsed to measure it? Thinking of getting one made up that wont hopefully go like this one.

Thinking of getting one made up that wont hopefully go like this one. It's the usual lack of Mr Kawasakis lubrication on assembly that causes this to corrode, coupled with British winters and the fact that that bolt in particular, is located in the very best place to catch all theh crud that gets thrown at it. By the time you've finished arsing about getting a new bolt made up you might just as well have bought the proper replacement from Cradley Kwak. Their mail order only takes a couple of days assuming the part is in stock. 01384 633455 I'm not giving these guys a plug simply because I know them. I only got to know them because of their friendly and efficient manner.

Funnily enough thats an old saying of mine as well (or rather my old seadads), and in fact that is exactly what I did, and new torsion bar fitted, and bolts polished and copperslipped before replacment. all. RESULT.
