Thanks Muskrat,
I'll try one of those pullers next chance, which may be soon. Sounds painful the way you put it though. *lol*
Rex, I do like the idea of using a tap. There would be no radial forces on the bush.
Olev & Muskrat, I think you may both be behind the times.!!

Hi Trevor, I cannot get my head around your modification. Any chance of a sketch.?
Is it like this picture.?

Col,
Remove the cone & leg holder from the shaft
Now screw on a threaded sleeve with a stepped stud in the other end.
Stud was a bolt with the head cut off & shank turned down & threaded  M8 x 1.5.

My kit had the collets for pulling oil seals and basically it was a collet center bolt.

Clever. I imagine putty or modeling clay, (Plasticine) would also work, maybe better as they'd have a denser structure.

I like the bread Idea. Would the oil hole on our cam bushes effect it working do you think?

Hi Trev ( BSA_54A10 ),
How did I do with my sketch of what I think you did.?
And Dutch, it is easier to put on the peanut butter BEFORE removing bush.  *bright idea*
The squishiness would also do the job better, and make the bread chewier afterwards. *lol*

I guess I'm confused, yet again. Unless you're collecting old bushings, why not cut it out with a Dremel grinder?

Hi Richard, My instinct was that I might be too rough with the Dremel, and cut into the base aluminium. I did not want to put any grinding machine near the crankcase. With experience and skill though maybe it is an option. *dunno*
