      A 0.2 kg will have no effect on this shaft and pulley,it will just bounce,also too many pieces of wood will also absorb a lot of the shock of the hammer blow,one good clout with a 4 lb club hammer with the angle iron mounted on concrete blocks should move it. The marks t 60 degreeson the end of the shaft may be from a very light means of rotating the shaft for balancing the rotor between centres.

        Lines left on the end of the shaft are from the 'Face Driver' used when the shaft was manufactured.

        Your two lengths of angle in conjunction with the clamps (I suggest you move them much closer to the spindle so less flexing) already form the part of a 'puller' that will be a far better job of dismantling than any press would do.

        If you cut a couple of notches in the webs of the angle either side of the pulley then the heads of two long bolts can be trapped under the webs. A stout plate with two holes and a bit of packing (a few washers even) on the end of shaft should be enough to place substantial pressure to get the pulley moving.

        One tip. No need to tighten the two bolts to the point of straining or bending anything, once you have loaded up the end pressure use a hammer to shock the shaft/pulley.

        No need for a club hammer just to apply the extra jolt

          Forget WD40 and get some Plusgas or diesel on it

            Heat the pulley to expand it while it is under tension from the puller.

            Concur with Ian P on the face driver marks – that was how Brook Crompton Parkinson made their shafts.

              Hi, I agree with Nigel B. about heating it while you've got your puller tight, even if you use a good hot air gun. Been there and done it a few times.

              Regards Nick.

                Victory! I bought a puller. The cheapest one. Toya turned out to be some kind of Yato brand. I tried to pull the pulley but of course it's claws were too thick. So I thought why not grind them a little. It turned out that just 1mm was enough. In the end was very simple.

                The pulley is made from steel. No markings. WD40 didn't reached all the contact surface.

                Thank you for all suggestion!

                  I have a couple of pullers similar to the ones shown above and they work well with an impact driver.
