Oh no.....

Yes the plain nut is to lock the bolt tight.

You are referring to the 12mm bolt in the tapped block that's welded to the flywheel wrap ? (19 mm spanner size).

That's why I suggested soaking it in penetrating oil or heating it up..

Unfortunately if it is this then there's no easy solution,  you could try welding a nut to the sheared bolt if you can get in with a welder ? 

The heat alone from welding may be enough to free it off , otherwise the only real option is to cut off the block either with a gas torch or a grinder and weld a new block back on..

Jase.

So the plain nut should have been backed off first? I didn't see it until now unfortunately. I had already soaked it in liberal amounts.

 

It really is the wildest amount of faff

By the way, I really appreciate you taking your time.

Yes , I did make a point of that in my original post but to be fair , the bolt was most likely seized anyway.

Do you think you can get a welder to it , or get someone to get the sheared stud out with a welder ?

Sorry I must have missed that.

I think I can get a welder to it. I will try tomorrow, if I am not too fed up with it.  I will make sure to let you know of the progress. I was thinking of taking off the exhaust, but is that a very bad idea?

You may need to but its fiddly and you'd likely need three new gaskets.

When they build the Arb 19-28 , one of the first parts to be fitted to the bare chassis is the exhaust as its the easiest time to get in there... the tricky part is where the exhaust flexi and silencer join and sandwich the chassis mounting bracket...

Can you live without the pusher bolt ?? 

[Jase hutch]

No it needs to be there , it keeps the shearbar pushed back firmly against the fabrication. Early 220 machines didn't have it and this could result in debris building up behind the shearbar overtime resulting in the blades touching the shearbar ! This was when it was introduced .

Funnily enough it was on a Good Friday many years ago that this was first discovered when I had to go out to a 220 working on the M50 that had started making a tapping noise and that was the reason.

Ok, so I will have to cut out the block. Someone else have been tampering with the whole setup, so it is a bit crooked, that's why I could get the bolt out a little and then it snapped. A few small pieces of metal has been welded on for some reason, and is has bend the whole section.

Wish me luck I guess. I will get back in a few days, when I know more  

 

Thanks again.
