Wd40 or similar penetrant instead of oil. They are so fine on a molecular level that they will squeeze into the tiniest gap if you give it a couple of hours, at least.
Umm, no!
At least, as far as WD-40 is concerned.
It is good only for getting water off surfaces, and to some extent, prevention of surface corrosion. It's a lousy penetrant, and an even worse lubricant.
If one evaporates off the hydrocarbon carrier, the residue is a
very sticky brown gum. This is so even if it's done at fairly low temperature, using vacuum to speed up the evaporation process... So it's not as if it's getting 'cooked' and polymerising during the process. BTDT. Penetrene or CRC 5-56, 6-66 etc are the top two I recommend.
For a press fitting lubricant, a substance that has good Extreme Pressure lubrication properties is best. A very good one, that's dead easy to get, is Anhydrous Lanolin [aka Wool Fat]. 'Lanox' aerosol contains quite a bit, or you can even buy it from the chemist!
I do know liquid nitrogen works well for this sort of thing, so putting it in the freezer in your kitchen inside a plastic shopping might make enough of a difference. That is what I would try.
The point to make here, is that it's the crankshaft only, that should go in the freezer.
And BTW Widget, see if you can find a piece of water pipe that just fits over the crankshaft end. Use that as a bearing inner race driver, and use a heavy hammer - 32oz ball peen at minimum.
But I guess you have to get the old bearing off first? Post up if you're still having trouble with that.
I suspect that the reason that first spacer is 'eccentric', is so that there's a bit sticking out to help with driving/pressing it off the shaft. The workshop manual isn't at all helpful here, but it should be possible to 'nut something out'.
