Well after a lot of huffing and puffing I have got the bearing in place.
I started with cooling it down to minus 18 in the freezer to shrink it although only succeeded in a small reduction. I then used an improvised puller to insert it having spread a liberal amount of Vaseline on it.
That got it about two-thirds inserted and so I resorted to the old approach – hit it with a big hammer- and if that doesn’t work use a bigger one.
I use a 14 pound (6kg) sledge hammer and with the help of someone else and using a big piece of wood as a dolly, I got it in.
