...Problem: The conrod still won't come off the crank pin. It looks like the conrod should be able to slide another millimeter, or so on the wrist-pin to allow the rod to move far enough away from the crankshaft to come off the crank-pin but it will not move that extra little teeny bit. I tried lightly prying on the rod from behind to see if I could get the conrod to slide on the wristpin the rest of the way, but no go. I don't want to wreck it, but if at some point I need to replace a bearing or P/L set, I won't be able to get the darn thing apart.
1QwkSport2.5r,
It must come apart like that, if for no other reason apart from the fact; that this is how it was put together in the first place...
Try turning the crankshaft to bring the piston to BDC; putting a medium,tie-wrap around the con-rod's top part and pulling back on it.
This should make the con-rod's top-end slide over/past an obstruction (most likely congealed castor oil) on the wrist-pin.
This, in turn, will allow the con-rod's bottom-end to be unhooked from the crank-pin...
The only other possibility, is that crankshaft is not fully seated in the rear bearing, or the rear bearings is not fully seated in the crankcase...
But since the prop-driver is still on the crank, this is very unlikely to be the case.
I didn't think about using a ziptie on the rod. Though the wristpin is clean and shiny; at least what's visible. I will try that and see what happens. I had the piston at bdc when trying to get it apart. I will try it again.
