Quickie Query

With apologies to purists......

The Nut is already marked so

Penetrating oil and leave overnight then try drifting with a heavy engineer’s screwdriver (flat blade with exposed tang at handle). Get the best tangential angle to give enough bite at the holes in the Nut - you are now going to tap it with a lump hammer!

Alternatively wrap the Nut with a few turns of duct tape and try a Stilson (pipe wrench). You may get teeth marks.

 

If you have an angle grinder - check to see if the disc spanner tool will go near. They are a sturdy pin spanner.

 

You could leave it soaking in penetrating fluid for a day and try one of these :-

It looks a bit stronger than the flat plate type pin wrenches?

 

That’s a toy!

I meant one of these



It tightens with pressure.

 

Yep, I realise that's what you were recommending - and it's looking like the best option, but it WILL require a lot of careful covering of the yoke itself and everything in the near vicinity in case it slips. There's very little shoulder on that nut for even the stilsons to hang onto and those handlebar risers look mighty close!

The angle of the yoke will also mean that the stilson is perilously close to the tank and there'll be little movement range available. A bit of foam pipe lagging on the handle might be a good idea. I'm thinking your idea of driving it out slowly with a lump hammer and either 'drive through' screw driver or a large pin punch will be the safest way to go.

 

Agreed. I would probably strip the bars down and remove the tank IF I could not slacken with my 4lb lump!
I might even try a nut splitter.

 

try a pin punch at an angle in one of the 6 holes, also a bit of heat wont do any harm (just remember the ignition wires are close by) or a small cold chisel and dig it deep into the nut.
That should at least get it moving.

That should at least get it moving. Oh nearly forgot a good lump hammer
but you knew that anyway

 

I had the same problem on my Daytona, it had been tightened by a gorilla.
I got it off with a hammer and punch, then bought a new nut and a proper six pinned socket to torque it up with.

 

Well done Daniel. Pour yourself a large one and relax with a self satisfied smile!
