At present, I am open to suggestions for removing the pulley without
destroying it... The grubscrew has been removed. penetrating oil (actually,
ether, kerosene and a drop of oil) has been applied and the pulley has been
heated as hot as I would want to take zinc (about 150 C).
So far, the pulley hasn't, yet, come free. I might have to turn up a clamp
ring to spread the load so that I can use a puller on it without wrecking the
pulley flanges.
It's older than JS, it's got an excuse to be curmudgeonly :-)

I had a go at a similar job recently and now need a new Picador 5M pulley
(2-3-4-5). My "solution" was to make a puller out of two pieces of
1/4" steel with M8 studding between and and M8 bolt in the top piece.
All that happened was the top piece of 1/4 steel bent. I also tried heat
penetrating oil all to availal. When it came off it was in three pieces!
There was mushrooming on the opposite end of the shaft which I had
to turn down in order to get the bearings off so I guess the clearly
non-original pulley may have been fitted with the aid of the nearest
handy hydraulic press.
As a side effect; if anyone has a spare 5M pulley (Z section belt) I'd
be interested in buying it.

Check down the hole for a second grub screw.
BTDT Broke the part learning it.

Interesting, My one was a B'strd to get off as well. Totally destroyed it in
the process, thinking I could just get one ex stock!!

So I'd better be cautious with this one then?
It looks as if the pulley on the motor may well be identical to the one on the
spindle, so at least that's a second option. I'm going to try to get some
decent penetrating oil down between the pulley and the quill for a few days.
When I've got the lathe unburdened, I'll try to turn up an adaptor to spread
the load onto one or two of the pulley flanges and make a puller for it. I
went as far as I felt safe with levers last night... about 50lbs on each of
two levers with 5-10:1 mechanical advantage.
Can always chisel the drill casting off of the quill I suppose :-)
I'll keep working on it unless I hear that your lad is heading up this way.

I have put an "alert" on this site to see if someone can offer a sensible
delivery price to save the hassle. Never used them, but worth a shot.
